The Complete Beginner’s Guide to CSS

**Feature queries** are used in CSS for precise feature detection and are now supported by all modern browsers!

We use the `@supports` keyword for feature queries, as shown in the example below:

```css
@supports (height: 100vh) {
  .container {
    height: 100vh;
  }
}
```

Here, we check if the `vh` unit is supported. If so, the `height` value is set accordingly.

Feature queries are structured much like media queries.

Let’s expand upon this example:

```css
.element {
  height: 100%;
}

@supports (height: 100vh) {
  .element {
    height: 100vh;
  }
}
```

We’ve provided a fallback by default, giving the element a `height` of `100%`. If the browser supports `vh`, then `100vh` applies instead.

The `@supports` keyword can be used for any available property in CSS.The logical operators, `and`, `or` and `not`, can also be used in feature queries. Let’s use `and` to check if CSS Grid and Flexbox are supported by the user’s browser:

```css
@supports (display: grid) and (display: flex) {
  /* ... */
}
```

The example given below checks if CSS Grid is supported:

```css
.element {
  float: left;
  ...
}

@supports (display: grid) {
  .element {
    float: none;
    display: grid;
    ...
   }
}
```
