Adding CSS <meta> tag with viewport is an efficient way to improve the web pages to look on smaller screens. The ViewPort is not the same size as the original Webpage If you use viewport length units in your CSS within the iframe document, 1vh will be 1% of the height of the iframe, and 1vw will be 1% of the width of the document. iframe { width : 50vw ; } If the iframe is set to 50vw, it will be 50% of the width of the 1200px parent document in our example above, or 600px , with 1vw being 6px The @viewport CSS at-rule lets you configure the viewport through which the document is viewed.

Une zone d'affichage (aussi appelée viewport en anglais) représente la zone actuellement visible sur l'appareil. Pour un navigateur web, la zone d'affichage correspond généralement à la fenêtre du navigateur sans les éléments d'interface du navigateur (barre de menu, etc.) * Viewport = the browser window size. If the viewport is 50cm wide, 1vw = 0.5cm Even if calc() worked in that context, it would be the wrong thing to use, because the viewport width could be between 40rem and 40rem + 1px (e.g. 640.5px on a 2× display with 16px base font size). In the custom properties and calc() section, for --spacing-L: var(--spacing) * 2; , I think it would be worthwhile noting that this is the place where nesting calc() is convenient The CSS viewport refers to the part of the website, which is visible in the browser window. Therefore, the viewport is usually not the same size as the actual page.

The default container for absolutely positioned elements is the viewport. (In case of a browser, that means the browser window). So centering an element in the viewport is very simple. Here is a complete example. (This example uses HTML5 syntax. The viewport is not an HTML construct, so you cannot influence it by CSS.

We've got viewport units (e.g. vw, vh, vmin, vmax ), and they are mostly pretty great. It's cool to always have a unit available that is relative to the entire screen. But when you ask people what they want fixed up in CSS, viewport units are always on the list However, CSS percentage measures are not always the best solution for all problems. The measure vh is equal to 1/100 of the height of the viewport. So, for example, if the height of the browser is 800px, 1vh equals 8px and, similarly, if the width of the viewport is 650px, 1vw is equivalent to 6.5px The viewport meta element is what turns a regular website page into a responsive page, and it's also one of the number one reason for StackOverflow questions on why their media queries are not working In the first SVG we see the entire 100px by 100px circle, but in the second SVG when we set our viewport size to 50px by 50px we only see a quarter of the circle..
