You could also set max-height, max-width, and/or min-height, min-width if you don't want it to grow ridiculously big or small, since it's based on the browser's width now and not the container and will grow/shrink indefinitely. include responsive-type ('') include responsive-type ('1.051900px', line-height) But Sass is giving me an error when I compile: index out of bounds for nth (list, n). * width within the parent (could use vw instead of course) */ Now, bumming off of Isaac's idea, it's easier in modern browsers to simply use vw units to force aspect ratio (although I wouldn't also use vh as he does or the aspect ratio will change based on window height). new ResizeObserver ( () > console.log ('resizing')). 100% means theĭiv will remain 100% as tall as it is wide, or That would scale font-size from a minimum of 16px (at a 320px viewport) to a maximum of 22px (at a 1000px viewport). But in order to get the iframe to show up inside the zero-height container, you need to make the container relative and the iframe absolute, positioned inside the div.Bumming off Chris's idea, another option is to use pseudo elements so you don't need to use an absolutely positioned internal element. Getting right to the code, here’s a working implementation: It’s worth looking at our more recent post Simplified Fluid Typography for practical, clamped, viewport-based type sizing.

How this works: The container element is given a zero height and a percentage bottom padding. container for a responsive fixed width container. Responsive Grids Layout Div with CSS and HTML The responsive grid design adjusts to screen size and direction, guaranteeing consistency crosswise over formats.

On screens smaller than 601 pixels it resizes to 100.

The w3-half Class The width of the w3-half class is 1/2 of the parent element (style'width:50'). It would be nice if we could just give it a 100% width, but it won't work as the height remains fixed. The responsive classes above must be placed inside a w3-row class (or w3-row-padding class) to be fully responsive. Here is what a typical YouTube embed code looks like, with fixed width and height: You can also use this technique with most other iframe-based embeds, such as slideshows.
