How to Verify CSS Property and Value Support in a Browser

When implementing CSS, it's crucial to ensure that your styles are supported by the user's browser. Let's investigate how to determine whether both CSS properties and values are supported.

Checking CSS Property Support

In CSS:

<code class="css">@supports (display: flex) {
  /* Code to be executed if flexbox is supported */
}</code>
Copy after login

In JavaScript:

<code class="javascript">if ('display' in document.body.style) {
  // Flexbox is supported
}</code>
Copy after login

Checking CSS Value Support

In JavaScript:

<code class="javascript">const element = document.createElement('div');
element.style.setProperty('text-decoration-style', 'blink');
const style = window.getComputedStyle(element);
if (style.getPropertyValue('text-decoration-style') === 'blink') {
  // Blink effect is supported
}</code>
Copy after login

However, there is a newer and more efficient method available:

CSS.supports()

The CSS.supports() API offers a more robust solution:

<code class="javascript">console.log(CSS.supports('text-decoration-style', 'blink'));
// True or false

console.log(CSS.supports('display', 'flex'));
// True or false

console.log(CSS.supports('--foo', 'red'));
// True or false</code>
Copy after login

This method supports both property and value validation.

By utilizing these techniques, you can confidently ensure that your CSS styles will be rendered as intended, regardless of the user's browser.
