Issue #147  (CSS.supports, Git/GitHub/CLI, Productivity, JS Utils)


(Skip to the tools section below)


You've probably heard of using @supports in your CSS to perform feature queries, similar to what we do with Modernizr or other feature detection scripts. Well, maybe you didn't know you can also do the same tests in your JavaScript using the CSS.supports() method. All browsers with the exception of IE11 and earlier have implemented @supports as well as CSS.supports().

It's simple to use:
 
// I ran these tests in Chrome
console.log(CSS.supports('display', 'flex')); // true
console.log(CSS.supports('object-fit', 'none')); // true
console.log(CSS.supports('color', 'currentColor')); // true
console.log(CSS.supports('hyphens', 'auto')); // false

As noted, I ran that code in Chrome, so three of the four tests returned true. Chrome doesn't support CSS hyphenation, so it returned false for the last one.

Instead of passing in two strings as a property/value pair (as I did in the examples above) you also have the option to use a supportCondition argument, which would look like this inside the log method:
 
CSS.supports('( animation: none ) or ( -webkit-animation: none )');

(JS Bin demo)

So it's basically the same idea as using @supports in CSS, so if you already know the syntax for @supports, then you know this too.
