css3 vw unit, объяснение vh unit и совместимость vw vh

Viewport units—VW (viewport width) and VH (viewport height)—have become popular tools in modern web design. These units provide an easy way to create responsive layouts by sizing elements relative to the size of the browser’s viewport. They offer a flexible alternative to fixed units like pixels or percentages, which can sometimes struggle to adapt across different devices and screen sizes. However, while viewport units seem straightforward, they can introduce a range of issues if not used carefully. From unexpected scroll behavior to performance hiccups, VW and VH can cause trouble if their limitations aren’t fully understood.In this article, we’ll explore the common pitfalls of viewport units, why they happen, and how to avoid them. We’ll cover everything from responsive design quirks to the intricacies of mobile browsers, and by the end, you’ll have actionable strategies to ensure your use of VW and VH is effective and problem-free.Understanding VW and VH: A Quick OverviewBefore diving into the pitfalls, let’s quickly define how viewport units work:VW: 1 VW unit equals 1% of the viewport’s width. If the viewport is 1000 pixels wide, then 1 VW equals 10 pixels.VH: 1 VH unit equals 1% of the viewport’s height. If the viewport height is 800 pixels, then 1 VH equals 8 pixels.These units allow you to size elements relative to the browser window, making it easier to create designs that scale with the screen size. For example, you might use width: 50vw to ensure an element always takes up 50% of the viewport’s width, regardless of the device size.But while VW and VH are flexible and convenient, they don’t always behave as expected—particularly when dealing with mobile devices, dynamic content, or more complex layouts.Pitfall #1: Mobile Viewport Height InconsistenciesOne of the most frustrating issues with VH units is how mobile browsers handle the viewport height. Mobile devices, unlike desktop browsers, often include dynamic UI elements like address bars and toolbars that appear and disappear as the user scrolls. These elements change the height of the viewport, causing VH-based elements to resize unexpectedly.The Problem:When you use VH on a mobile device, the viewport height can change depending on whether the browser’s address bar is visible. For instance, if you set an element to height: 100vh, it may look fine initially, but as the user scrolls and the browser’s UI collapses, the viewport height increases, causing the element to resize and potentially creating a layout shift.Example:.hero

In the dynamic realm of web design, the ability to create adaptive layouts hinges on a profound understanding of viewport dimensions. This in-depth exploration focuses on viewport-based measurement units in CSS, namely viewport height (vh), viewport width (vw), viewport minimum (vmin), and viewport maximum (vmax). These units are inherently responsive, altering in real-time as the browser window changes size, thereby providing designers with unparalleled adaptability and precision in crafting web interfaces.Vital Role of the Viewport in Web DesignThe viewport, essentially the gateway through which digital content is consumed, plays a critical role in shaping user experience in web design. Accurate measurements and strategic use of this visual interface area are essential as they profoundly influence how users interact with a website. Customizing web components to align with the viewport’s dimensions has been transformative, enabling designers to create more fluid and user-centric designs, such as tailoring the height of elements to seamlessly match the browser’s window height.Deciphering Viewport-Related MeasurementsViewport Height (vh):Description: ‘vh’ signifies the height of the viewport;Computation: 1vh equals 1% of the viewport’s total height, thus 100vh represents the full height of the viewport.Viewport Width (vw):Description: ‘vw’ indicates the width of the viewport;Computation: 1vw is equivalent to 1% of the viewport’s overall width, with 100vw encompassing the viewport’s complete width.Viewport Minimum (vmin):Description: ‘vmin’ is calculated from the smaller dimension of the viewport;Usage: When the viewport’s height is less than its width, 1vmin is 1% of the height. If the width is the lesser dimension, 1vmin is 1% of the width.Viewport. vh and vw defined. vw and vh are length units representing 1% of the viewport size for viewport width (vw) and height (vh), respectively. Wondering what browsers support vh and vw? Browser support for vh and vw units is Vh and vw units are ideal for responsive design because they are completely independent of the base font size. vh and vw defined. vw and vh are length units representing 1% of the viewport size for viewport width (vw) and height (vh), respectively.

What is VW and VH in CSS?

Combining VW and VH with other fluid units like percentages or rems can sometimes lead to conflicting behavior, where elements scale too aggressively or fail to align properly.The Problem:When combining fluid units like VW with percentages or em-based layouts, the elements may not scale proportionally, leading to awkward spacing or misaligned content.Example:.container { width: 80vw;}.text { font-size: 2rem; margin: 5%; /* Percentages and viewport units might conflict */}In this case, the text size and margin may not align well with the container, especially as the viewport resizes.The Fix:To create a more consistent fluid layout, use consistent units across your design. If you’re using viewport units for width or height, consider using them for spacing and font sizes as well to ensure a harmonious scaling experience. Alternatively, use a combination of fluid typography and CSS Grid or Flexbox to maintain a balanced layout.Example of a fluid layout with consistent units:.container { width: 80vw; padding: 5vw; /* Consistent spacing with VW */}.text { font-size: 3vw; /* Scales with viewport */}By keeping the units consistent, you avoid conflicts and ensure that all elements scale proportionally, creating a smoother, more balanced fluid layout.Conclusion: Mastering VW and VH with Best PracticesViewport units are incredibly powerful for creating responsive designs that scale effortlessly across devices. However, as we’ve seen, they can introduce a range of issues—from mobile viewport height inconsistencies to unexpected scrollbars and layout shifts. To master VW and VH, it’s important to understand their limitations and use them strategically.Here’s a summary of best practices for avoiding the pitfalls of viewport units:Use CSS custom properties and JavaScript to manage viewport height (VH) on mobile devices where the UI can change dynamically.Avoid using 100vw for full-width elements to prevent horizontal scrollbars—use 100% or adjust for the scrollbar width.Let Flexbox or Grid control layout sizes and avoid mixing viewport units with these layout techniques.Adjust for large screens using media queries to prevent elements from scaling too large.Predefine sizes for dynamic content like images or videos to prevent layout shifts during loading.By following these strategies, you can take full advantage of viewport units without falling into the common traps that can harm the user experience. At PixelFree Studio, we believe that the best designs are not only responsive but also stable and performant. By mastering VW and VH and understanding their intricacies, you can create layouts that look polished and behave predictably, no matter the device or screen

Довжина перегляду відсотка відсотків, або одиниці вигляду оскільки вони частіше згадуються, є реагують CSS одиниці, які дозволяють визначати розміри у відсотках від ширини або довжини вікна перегляду. Одиниці перегляду можуть бути дуже корисними у випадках, коли інші відповідні CSS-одиниці, такі як відсотки, є Важко працювати. Хоча Документація W3C на оглядових одиницях є все, що можна ввести в теорію, це не дуже багато. Отже, у цій статті ми розглянемо, як ці CSS-одиниці на практиці. Висота вікна перегляду (vh) & ширина вікна перегляду (vw) W3C визначає вікно перегляду як “розмір початкового містить блок”. Іншими словами, область перегляду - це область у вікні браузера або будь-яку іншу область перегляду на екрані. The vw і vh одиниць позначають відсоток ширини і висоти фактичного вікна перегляду. Вони можуть приймати значення від 0 до 100 відповідно до таких правил: 100vw = 100% від ширини вікна перегляду 1vw = 1% від ширини вікна перегляду 100vh = 100% від висоти вікна перегляду 1vh = 1% від висоти вікна перегляду Відмінності у відсоткових одиницях Отже, яким чином одиниці видового екрану відрізняються від відсотків? Відсоткові одиниці успадковує розмір батьківського елемента а одиниці перегляду не. Одиниці перегляду завжди розраховуються як відсоток від розміру вікна перегляду. В результаті, елемент, визначений блоками вікна перегляду, може перевищувати розмір його батьківського. Приклад: Повноекранні розділи Повноекранні розділи мабуть, найбільш широко відомі випадки використання одиниць видового вікна. The HTML досить простий; ми просто маємо три секції один під одним і ми хочемо, щоб кожен з них накрийте весь екран (але не більше). У CSS ми використовуємо 100vh як висота значення і 100% як ширина. Ми не використовуємо vw тут, як за замовчуванням, також додаються смуги прокручування до розміру вікна перегляду. Отже, якщо ми використали ширина: 100vw; правило a горизонтальна смуга прокрутки з'явиться на внизу вікна браузера. * margin: 0; заповнення: 0; розділ розмір фону: обкладинка; фонове положення: центр; ширина: 100%; висота: 100вч; .section-1 background-image: url (' .section-2 background-image: url (' .section-3 background-image: url (' На нижченаведеному показі gif ви можете побачити це vh є дійсно чуйний блок. Згідно з документами W3C, вищезазначене горизонтальної смуги прокрутки можна вирішити, додавши переповнення: авто; правило до кореневого елемента. Це рішення працює лише частково, хоча. Горизонтальна смуга прокрутки, дійсно, зникає, але ширина є все ще обчислюється на основі ширини вікна перегляду (бічна панель включена), тому елементи будуть трохи більшими, ніж вони повинні бути. Я б сказав, що не смію використовувати vw блок визначення розміру повноекранних елементів з цієї причини. Нам навіть не потрібно, як ширина: 100%; правило працює відмінно. З повноекранними макетами справжнім завданням завжди було те, як це зробити встановити правильне значення висоти і vh блок дає блискуче рішення для цього.

vh and vw units - DEV Community

{ height: 100vh; /* Takes the full height of the viewport */}This approach works well on desktop but can cause jarring behavior on mobile as the viewport height changes dynamically.The Fix:A common solution to this problem is using CSS custom properties and JavaScript to calculate and update the correct height dynamically. This ensures the height remains stable even when the viewport changes on mobile devices.// Calculate the real viewport height and set it as a custom propertyfunction updateVH() { let vh = window.innerHeight * 0.01; document.documentElement.style.setProperty('--vh', `${vh}px`);}window.addEventListener('resize', updateVH);updateVH(); // Call on initial loadThen, in your CSS, you can use this custom property:.hero { height: calc(var(--vh, 1vh) * 100); /* Uses the calculated viewport height */}This method ensures that your design remains consistent, even on mobile browsers with dynamic UI elements.Pitfall #2: Scrollbars and Viewport Width (VW)When working with VW units, another common issue is the presence of scrollbars. On some devices or browsers, vertical scrollbars take up space on the screen but are not accounted for in the viewport width. This can cause elements sized with VW to be slightly too wide, leading to unintended horizontal scrolling.The Problem:If you set an element’s width to 100vw, it will take up the entire width of the viewport, including the area occupied by a vertical scrollbar. This can push content slightly beyond the viewport, causing a horizontal scrollbar to appear.Example:.container { width: 100vw; /* Includes scrollbar width, causing overflow */}On browsers where scrollbars overlap the content (such as macOS browsers with hidden scrollbars), this may not be a problem. But on Windows or other platforms where scrollbars take up space, the container will be wider than the visible area, leading to horizontal scrolling.The Fix:To avoid this issue, use a combination of CSS and JavaScript to calculate the correct width, excluding the scrollbar. You can use 100% width instead of 100vw, or dynamically adjust the width to account for the scrollbar:.container { width: 100%; max-width: 100vw; /* Ensures no overflow even with scrollbars */}Alternatively, use JavaScript to calculate the difference between the viewport width and the scrollbar:function updateContainerWidth() { let vw = window.innerWidth - document.documentElement.clientWidth; document.documentElement.style.setProperty('--container-width', `${vw}px`);}window.addEventListener('resize', updateContainerWidth);updateContainerWidth();This approach gives you more precise control over the element’s width and prevents the appearance of unexpected scrollbars.Pitfall #3: Issues with Nested Flexbox and Viewport UnitsViewport units can also cause issues when combined with Flexbox layouts, particularly when flex containers are nested. In some cases, using VW. vh and vw defined. vw and vh are length units representing 1% of the viewport size for viewport width (vw) and height (vh), respectively.

VH and VW units explained - YouTube

What are CSS Units?CSS units are measurements used to specify the size of elements, fonts, and spacing in a web page. They determine how content is rendered on different devices and screen sizes. Common units include px (pixels), rem (root em), em, vw (viewport width), vh (viewport height), and percentages ( % ).What is the difference between absolute and relative units?CSS units are categorized into absolute and relative units. Absolute units (e.g., px, cm, mm) represent fixed sizes, irrespective of the context. Relative units (e.g., rem, em, %, vw, vh) depend on other factors like the root font size, parent element size, or viewport dimensions, making them more flexible for responsive designs.What are pixels (px) in CSS?Pixels are the most commonly used CSS unit. They represent a fixed size and are not affected by parent or root elements. One pixel corresponds to one dot on the screen. While they offer precision, they can hinder responsiveness.What is the difference between rem and em?rem (root em) is relative to the root element’s font size, while em is relative to the font size of the parent element. For example, if the root font size is 16px, 1rem equals 16px, and if a parent element's font size is 20px, 1em within it equals 20px.When should you use rem instead of em?rem is ideal for consistent scaling across elements, as it is always relative to the root font size. em is better for scaling elements relative to their parent, useful for nesting layouts where each element’s size adapts proportionally to its container.What are viewport units (vw and vh)?Viewport units are relative to the browser window dimensions. 1vw equals 1% of the viewport width, and 1vh equals 1% of the viewport height. They are often used for responsive typography, margins, or dynamic layouts.How does the root font size affect rem and em?The root font size defines the base size for rem. By default, browsers set it to 16px, but you can modify it using the element’s CSS property. For example, setting html { font-size: 10px; } makes 1rem equal to 10px.What does percentage (%) represent in CSS?Percentages are relative to the parent element. For example, if an element’s width is set to 50%, it will occupy half of its parent’s width. Percentages adapt to changes in the parent element's dimensions, making them ideal for responsive designs.How do CSS units impact responsive design?Responsive design benefits from relative units like rem, %, vw, and vh, which adapt to screen sizes, resolutions, and user preferences. Avoid absolute units like px for layouts intended to scale across devices.What are the best units for font sizes in CSS?rem is preferred for font sizes because it scales consistently with the root font size. em is used when you want font sizes to adapt to the parent element’s size, and px is ideal for fixed typography when responsiveness is not a priority.How are vw and vh used for layouts?Viewport units vw and vh are excellent for fluid layouts. For instance, setting width: 100vw;

CSS tests - The vw and vh units

Or VH for sizing in combination with Flexbox can lead to unexpected overflow or misalignment.The Problem:When a flex container or its children use VH or VW for height or width, the browser may calculate the dimensions in ways that don’t align with the expected flex behavior. This can cause overflow, unexpected scrolling, or incorrect alignment.For example, a child element using 100vh inside a flex container may expand beyond the intended space, especially if the flex parent is designed to scroll or shrink based on content.Example:.flex-container { display: flex; height: 100vh; /* Full height of the viewport */}.flex-item { height: 100vh; /* Can cause overflow or incorrect sizing */}The Fix:To prevent conflicts between Flexbox and viewport units, avoid mixing these two layout techniques for critical sizing. Instead of using VH or VW, allow Flexbox to manage the layout, and only use viewport units for elements that are truly independent of the flex container’s sizing.Example:.flex-item { flex-grow: 1; /* Let Flexbox manage the size */ min-height: 0; /* Prevent overflow */}By letting Flexbox control the size, you avoid the common pitfalls of combining it with viewport units.Pitfall #4: Oversized Elements on Large ScreensOne of the core benefits of VW and VH is their responsiveness. However, this flexibility can backfire on large screens. If you size elements purely based on viewport units, they can grow excessively large on large monitors or TVs, leading to awkwardly scaled content and poor usability.The Problem:When using large viewport units like width: 80vw or height: 90vh, elements can scale up dramatically on devices with larger screens, making text and other UI components disproportionately large.Example:.hero-title { font-size: 10vw; /* Looks great on mobile, but too large on large screens */}On a mobile device, 10 VW might translate to 32 pixels, but on a 4K display, it could become unmanageably large.The Fix:To handle large screens more effectively, use media queries to adjust viewport-based units based on screen size. This way, you can cap the scaling effect and prevent elements from becoming too large.Example with media queries:.hero-title { font-size: 10vw; /* Works for smaller screens */}@media (min-width: 1200px) { .hero-title { font-size: 6vw; /* Scales down on larger screens */ }}This method ensures that your design remains responsive without becoming overwhelming on large displays.Pitfall #5: Layout Shifts with Dynamic ContentAnother issue with viewport units is their interaction with dynamic content. If your page includes elements that load after the initial page. vh and vw defined. vw and vh are length units representing 1% of the viewport size for viewport width (vw) and height (vh), respectively. Wondering what browsers support vh and vw? Browser support for vh and vw units is Vh and vw units are ideal for responsive design because they are completely independent of the base font size. vh and vw defined. vw and vh are length units representing 1% of the viewport size for viewport width (vw) and height (vh), respectively. Wondering what browsers support vh and vw? Browser support for vh and vw units is generally good

em, rem, vw, vh in CSS

Render (such as images, videos, or iframes), these elements can cause unexpected layout shifts, particularly if their size is defined using VW or VH.The Problem:Dynamic content can cause elements sized with VW and VH to resize or shift as the viewport adjusts. This can lead to content jumping or reflowing unexpectedly, especially when combined with lazy-loading techniques.Example:.image-container { width: 50vw; height: 50vh; /* Sized to viewport, but shifts when content loads */}If the image takes longer to load or if additional content is inserted after the page render, the element’s size might shift, leading to layout instability.The Fix:To avoid layout shifts, always provide fallback dimensions for elements that rely on dynamic content. Predefine the dimensions for images, videos, and other media to ensure that the layout remains stable as the content loads..image-container { width: 50vw; height: 50vh; background-color: #e0e0e0; /* Placeholder color to prevent shifts */}Alternatively, use the CSS property aspect-ratio to maintain a consistent size for media elements, even before they load:img { aspect-ratio: 16/9; width: 100%; height: auto;}This approach ensures that the layout remains stable and prevents unexpected shifts when dynamic content is introduced.Advanced Techniques for Handling Viewport Units in Complex LayoutsNow that we’ve covered the basic pitfalls and solutions for viewport units (VW and VH), let’s explore some advanced techniques for dealing with more complex layouts. Whether you’re working with intricate grid systems, integrating third-party widgets, or ensuring accessibility, understanding how to handle viewport units in these scenarios can make or break the success of your design.1. Combining Viewport Units with CSS Grid for Complex LayoutsCSS Grid is one of the most powerful layout tools in modern web design, and it can work harmoniously with viewport units when used correctly. Grid allows you to create intricate layouts without the need for complicated positioning or flex hacks. However, viewport units can introduce issues in grid-based layouts, especially when grid items are sized using VW or VH.The Problem:When grid items use VW or VH for their width or height, they may not respond well to changes in content size or dynamic resizing, leading to overflow issues, misalignment, or excessive white space. This can be particularly problematic in responsive designs where grid layouts need to adjust seamlessly across devices.Example:.grid-container { display: grid; grid-template-columns: 1fr 1fr; grid-gap: 20px; height: 100vh; /* Full viewport height */}.grid-item { width: 50vw; /* May cause misalignment or overflow in the grid */}The Fix:When using CSS
