Package Exports

cq-prolyfill
cq-prolyfill/postcss-plugin

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cq-prolyfill) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Container Queries Prolyfill

MIT

This is a prolyfill for a special version of container queries (aka element queries). You can read more about the idea and how they work internally in this article.

Demo

A quick demo of the container queries in action can be found here: https://ausi.github.io/cq-prolyfill/demo/

Usage

With this prolyfill you can use container queries in your CSS in the following form:

.element:container(min-width: 100px) {
    /* Styles for .element if its container is at least 100px wide */
}
.element[data-cq~="min-width:100px"] {
    /* Alternative syntax, same as the container query above */
}
.element:container(text-align = right) {
    /* Styles for .element if its container has a right text-align */
}

For more information take a look at the usage documentation.
