5 sourcesEQCSS: A CSS Extension for Element Queries and More
2 points · Open discussionThanks, it is ambitious and introduces new features, but at the same time getting element queries working in IE8 requires a lot of polyfilling - keep in mind IE8 doesn't even natively support @media queries.
I think of it can be considered a polyfill and plugin at the same time, though it's quickly turning into a language extension for CSS with things unrelated to element queries that take advantage of the CSS scoping that the element queries plugin makes possible.
Check out some of the features possibly coming soon: https://github.com/eqcss/eqcss/issues/3
In Show HN: EQCSS, the Element Query polyfill hits v1.0.0> JavaScript has shown us the value of designing new features in a way that they can be polyfilled or emulated via a preprocessor, so that features can gain adoption without developers having to wait for older browsers to die.
Funny you should mention that, I have such a polyfill to introduce Element Query syntax to all browsers IE8 and up, and one of the features we just added was the ability to use variables in your CSS supplied from JavaScript running on the page.
Demo: http://codepen.io/tomhodgins/pen/MKWOWW
Oh, and we also added a $parent selector to CSS, just for giggles :)
http://github.com/eqcss/eqcss < it's under MIT so feel free to use it and build on it
In Why I'm Excited About Native CSS VariablesIf you're looking for a way to use JavaScript variables directly in CSS styles there is an Element Query polyfill that includes that feature: http://codepen.io/tomhodgins/pen/MKWOWW
You can reference one line of JS in your CSS style, and the returned value is what is output in your CSS at the time the (responsive) style applies. This value can be a Js variable set elsewhere on the page, the output of a function, or a string or single line of JavaScript that is evaluated in-place.
The var() feature is new and only in the v1.0.0 branch right now, but to read about the other features of this plugin check out https://github.com/eqcss/eqcss and http://elementqueries.com
