color-mix() (#13972)
* ensure opacity modifier variables work as expected
We use `color-mix()` in v4 which means that we can use this for the
opacity modifier. One thing we do already is convert values such as
`0.5` to `50%` because that's what the `color-mix()` function expects.
However, if you use a variable like this:
```html
<div class="[--opacity:0.5] bg-red-500/[var(--opacity)]"></div>
```
This currently generates:
```css
.bg-red-500\/\[var\(--opacity\)\] {
background-color: color-mix(
in srgb,
var(--color-red-500, #ef4444) var(--opacity),
transparent
);
}
.\[--opacity\:0\.5\] {
--opacity: 0.5;
}
```
Which won't work because the opacity variable resolves to `0.5` instead
of the expected`50%`.
This commit fixes that by always ensuring that we use `* 100%`.
- If you already had a percentage, we would have `calc(50% * 100%)`
which is `50%`.
- If we have `0.5` then we would have `calc(0.5 * 100%)` which is also
`50%`.
* wrap everything but percentages in `calc(… * 100%)`
* use `else if`
* update changelog
