Contents Definition Usage Importance Viewport FAQ What is a viewport? What is the viewport meta tag? How is the viewport meta tag used? Why is the viewport meta tag important? Are there any default values for the viewport that I should know about? Is the viewport meta tag the only element to consider when it comes to device compatibility? Is it necessary to include the viewport meta tag in the web page? ReferencesDefinitionA viewport is a user interface feature of a web browser that determines how a website's content is displayed on a device's screen[1]. The viewport is the area of the screen that a website is rendered in, and it can be controlled by the web developer through the use of the viewport meta tag in the website's HTML code.UsageThe viewport meta tag is used to set the width and initial scale of the viewport, and it can be used to optimize the website's layout for different device screen sizes. For example, a website that is designed for desktop computers may not display correctly on a mobile device with a smaller screen. By using the viewport meta tag, a web developer can ensure that the website is properly scaled and laid out for the specific device being used to view it.The most common usage of the viewport meta tag is:This tells the browser to set the width of the viewport to the width of the device and set an initial scale of 1.0, which means that the website will be displayed at its original size.ImportanceThe viewport meta tag is particularly important for mobile web development, as it allows web developers to ensure that a website's layout and navigation are optimized for small screens and touch-based input. It is also used in responsive web design.Keep in mind that different devices may have different default values for the viewport, and you may have to adjust the settings accordingly to better fit the expected layout on that device. Additionally, while this meta tag is important, it is not the only element to consider, other CSS and javascript can also impact how the website is displayed on different devices.Viewport FAQWhat is a viewport?A viewport is a user interface feature of a web browser that determines how a website's content is displayed on a device's screen.What is the viewport meta tag?The viewport meta tag is used in the HTML code of a website to

Viewport Units Buggyfill™This is a buggyfill (fixing bad behavior), not a polyfill (adding missing behavior). That said, it provides hacks for you to get viewport units working in old IE and Android Stock Browser as well. If the browser doesn't know how to deal with the viewport units - vw, vh, vmin and vmax - this library will not improve the situation unless you're using the hacks detailed below. The buggyfill uses the CSSOM to access the defined styles rather than ship its own CSS parser, that'S why the hacks abuse the CSS property content to get the values across.Amongst other things, the buggyfill helps with the following problems:viewport units (vh|vw|vmin|vmax) in Mobile Safariviewport units inside calc() expressions in Mobile Safari and IE9+ (hack)vmin, vmax in IE9+ (hack)viewport units in old Android Stock Browser (hack)The buggyfill iterates through all defined styles the document knows and extracts those that uses a viewport unit. After resolving the relative units against the viewport's dimensions, CSS is put back together and injected into the document in a element. Listening to the orientationchange event allows the buggyfill to update the calculated dimensions accordingly.The hacks use the content property to transport viewport-unit styles that need to be calculated by script, this is done because unsupporting browsers do not expose original declarations such as height: calc(100vh - 10px):content: 'viewport-units-buggyfill; width: 50vmin; height: 50vmax; top: calc(50vh - 100px); left: calc(50vw - 100px);';Note: The content hack may not work well on and other replaced elements, even though it should

Our HTML & CSS tutorial provides an in-depth guide on controlling how a webpage is displayed on mobile devices, including exercises on disabling mobile browser text size adjustment and understanding the viewport meta tag. This exercise is excerpted from Noble Desktop’s past front-end web development training materials and is compatible with updates through 2022. To learn current skills in web development, check out our coding bootcamps in NYC and live online. Topics covered in this HTML & CSS tutorial: Disabling mobile browser text size adjustment, The viewport meta tag, device-width, initial-scale, maximum-scaleExercise PreviewExercise OverviewThe viewport meta tag controls how a webpage is displayed on a mobile device. Without the viewport set, mobile devices will render the page at a typical desktop screen width, scaled to fit the screen. Setting a viewport gives control over the page’s width and scaling on different devices. If you completed the previous exercise, you can skip the following sidebar.

The Browser Viewport : HTML and CSS - BrainBell

Throughout this document. This section explains a few of the key terms used.The ICBThe Initial Containing Block (ICB) is the containing block of the root element. For continuous media it has the dimensions of the viewport and is anchored at the canvas origin.The ICB forms the basis of sizing and positioning for the root element’s box. Put differently: if you set the element’s size to 100% on both axes, it'll match the size of the ICB.In the visualizations below, the ICB is given a red dashed border.Figure: Visualization of the ICB in Safari on iOS (left), Chrome on Android (center), and Firefox on Android (right)The size of the ICB is not affected by any dynamic toolbars the browser interface might have. These “dynamic toolbars” are User Agent Interface Elements that expand and retract as you interact with the page.Figure: Visualization of the ICB with contracted UA UI in various browsers. Note that the ICB does not get resized with the dynamic UA UI Elements contracted.ℹ️ Note: The ICB does get resized on one occasion: when classic scrollbars are present. This is because the presence of those scrollbars resizes the Viewport. Since the ICB takes its size from that Viewport, it also gets resized. Overlay Scrollbars do not affect the Viewport nor ICB size.Viewport-Relative LengthsThe values for Viewport-relative lengths are derived from the size of the ICB. All browsers on all platforms agree on how this is done for the height:The Small Viewport Height (100svh) is equal to the ICB’s height.The Large Viewport Height (100lvh) is equal to the ICB’s height + height of any dynamic toolbars the browser has.In the visualizations below, both the Small and Large Viewport Heights are visualized, along with the ICB.Figure: Visualization of the svh and lvh units, with expanded UA UI in various browsers.Figure: Visualization of the svh and lvh units, with contracted UA UI in various browsers.Not visualized is the Dynamic Viewport, which adapts itself as UA UI Elements expand and/or contract.
