Scaling CSS to fit both height and width (Stretch)

Question

Scaling CSS to fit both height and width (Stretch)

My content is contained within an 800x480 pixel box. When the window size changes, I want to achieve the following:

Expand/Stretch the container to fill the entire screen
Include all elements inside the container and maintain their relative positions
I am not concerned about preserving the aspect ratio

For example, if the window dimensions are 1600x960, I would:

zoom: 2

This action will stretch the canvas, but if the new aspect ratio differs from 800x480, it may not fully expand in both height and width.

Is there a way to independently set the stretching factor for both width and height?

zoom: (2, 2.5)

Answer №1

To achieve a zoom effect where width and height are adjusted independently, you can utilize the CSS scale property. By applying transformations to the X and Y axis separately, you can simulate a zooming effect:

transform: scaleX(2) scaleY(1.5);

body,html{margin:0;}
.wrap{
    width:400px;
    height: 240px;
    background:gold;
    text-align:center;
    overflow:hidden;
    transform-origin: 0 0;
    transform: scaleX(2) scaleY(1.5);
}

<div class="wrap">
    <h1>Title</h1>
    <img src="https://loremflickr.com/640/360" />
    <p>Some text</p>
</div>

Remember to specify a transform origin of 0 0 to prevent cropping of the top/left part of your element by the viewport.

Consider using viewport width-height for your layout

div#content{
    width: 100vw; // This element's width is equal to 100% of the viewport's width
    height: 100vh; // This element's height is equal to 100% of the viewport's height

     font-size: 1vmax; // Adjust this to control the font size as needed
}

To maintain relative positions of elements, apply the same rule for top and left CSS properties

Although not universally supported, polyfills are available here to enable functionality in older browsers like IE8
