# PostCSS Overflow Clip

[PostCSS] plugin that adds [`overflow: clip`](https://developer.chrome.com/blog/new-in-chrome-90/#overflow-clip) whenever `overflow: hidden` is used.

If you want fallbacks for `overflow: clip`, please use https://www.npmjs.com/package/postcss-overflow-fallbacks

[PostCSS]: https://github.com/postcss/postcss

```css
.foo {
    overflow-x: clip;
}

.bar {
    overflow: auto hidden;
    overflow-block: hidden;
}
```

becomes

```css
.foo {
    overflow-x: clip;
}

.bar {
    overflow: auto hidden;
    overflow: auto clip;
    overflow-block: hidden;
    overflow-block: clip;
}
```

With `preserve: false`:

```css
.foo {
    overflow-x: clip;
}

.bar {
    overflow: auto hidden;
    overflow-block: hidden;
}
```

becomes

```css
.foo {
    overflow-x: clip;
}

.bar {
    overflow: auto clip;
    overflow-block: clip;
}
```
