Simple property check

Check for support specific technologies browser with using JavaScript is rightfully considered the best practice for client-side development ( Another method is often used, which is to check from which browser the user is viewing the page - Note. lane), but unfortunately such a check could not be done using CSS alone. Firefox, Chrome and Opera recently announced support for the @supports and CSS.supports (JavaScript) CSS directives, which will help developers determine whether the user's browser can handle CSS property or not. Let's see them in action!

Check your browser
(If the inscription is green, then your browser supports @supports, if it is red, then it does not. You can also look at the message in the browser console.)

CSS @supports

The syntax of the @supports directive is the same as the @ media queries:
@supports(prop:value) ( /* styles */ )
The @supports directive provides developers with various options its use.

Simple property check

@supports (display: flex) ( div ( display: flex; ) )
This is the easiest way to use.

Keyword not

@supports paired with the word not checks to see if a property is not supported:
@supports not (display: flex) ( div ( float: left; ) /* alternate style set */ )

Multiple checks and conditions

Multiple checks can be done using a chain of words or and and:
/* or */ @supports (display: -webkit-flex) or (display: -moz-flex) or (display: flex) ( /* add your cool styles here */ ) /* and */ @supports (display : flex) and (-webkit-appearance: caret) ( /* and we’ll add here too */ )
If you need to perform several multiple checks, then, as in many programming languages, you can use parentheses:
/* and and or */ @supports ((display: -webkit-flex) or (display: -moz-flex) or (display: flex)) and (-webkit-appearance: caret) ( /* styles here */ )
The syntax of @supports conditions is the same as that of @media queries.

JavaScript CSS.supports

The JavaScript counterpart to @supports is the window.CSS.supports method. There are two options for using it. The first involves passing two arguments - a property and its value:
var supportsFlex = CSS.supports("display", "flex");
The second option requires passing the entire string as an argument:
var supportsFlexAndAppearance = CSS.supports("(display: flex) and (-webkit-appearance: caret)");
Before using JavaScript analogue, it is important to first check the browser’s support for this technology. Opera uses a different method name, which makes the code slightly longer:
var supportsCSS = !!((window.CSS && window.CSS.supports) || window.supportsCSS || false);

Using @supports

In most cases, The best way using @supports is to set a specific fallback set of styles and then replace them with others in case required property supported. A great reason to use @supports is to describe the layout of elements. Some latest browsers support flexbox while the rest are lagging behind. In this case, you can write the following code:
section ( float: left; ) @supports (display: -webkit-flex) or (display: -moz-flex) or (display: flex) ( section ( display: -webkit-flex; display: -moz-flex; display : flex; float: none;
Examples of other successful use cases for @supports will emerge as developers spend more time experimenting with this new technology.

@supports connection

If you're eager to try new technologies like @supports , you should spend some time installing the latest edge version Canary browser, Firefox Nightly, or Opera Next. Opera 12.1, WebKit Nightly and Firefox Nightly all support @supports. Old Firefox versions provide appropriate support after the rule is enabled.

@supports is a welcome addition to the CSS and JavaScript specifications. Determining whether a browser supports specific technologies - best practice, and @supports is more convenient and in a suitable way for this than various hacks. I suspect we'll see a surge in use of the @supports directive over the next couple of years, as flexbox increases in popularity and convenience.
