Fylgja component - Aspect Ratio

The aspect ratio component is used to set videos to a certain responsive aspect ratio,

but can also be used for images and other content.

Installation

npm install @fylgja/aspect-ratio

Then include the component in to your code via;

@use "@fylgja/aspect-ratio";
// Or via PostCSS import
@import "@fylgja/aspect-ratio";

How to use

To use the aspect-ratio, create element with the class .aspect-ratio, any child of the aspect-ratio will now always be show in the ratio set by the class.

16/9 is the default ratio.

To edit the ratio use the css variable with the same name.

<div class="aspect-ratio" style="--aspect-ratio: 21/9;">..</div>

Config

As with almost all of our components, CSS variables can be configured to add your own look/style.

Want direct control on the base styles, here are the following SCSS variables can you modify.

$aspect-ratio: "16/9" !default;

PostCSS Calc & CSSNano issue

At the moment PostCSS Calc, which is also part of CSSNano, has an open issue where is removes the parentheses around a nested calc, this breaks the CSS aspect ratio calc.

You can at the moment work around this issue by;

• Wrapping the value from the CSS variable in parentheses.
• Using a multiplier instead
• CSSNano: disabling the calc minification

cssnano: {
    preset: ['default', {
        calc: false
    }]
}
