Write CSS rules for specific browsers

There are cases where we want styles to target a particular browser. We can use CSS feature queries with a declaration that is only available on the target browser.
For example, Firefox is only browser supporting
`-moz-appearance: none`, the following snippet can be used to target Firefox only:css
@support (-moz-appearance: none) {
/* Styles for Firefox only */
}The
`not` operator is useful to exclude the target browser:css
@support not (-moz-appearance: none) {
/* Styles for browser except Firefox */
}There is another, less popular hack for targeting Firefox only:
css
@-moz-document url-prefix() {
/* Styles for Firefox only */
}#Target Safari
css
@supports (background: -webkit-named-image(i)) {
/* Styles for Safari only */
}#Target Chromium
Since only Chromium based and Firefox browsers support the
`contain: paint` declaration, we can combine `and` and `not` operators to exclude Firefox from the target browsers:css
@support (contain: paint) and (not (-moz-appearance: none)) {
/* Styles for Chromium only */
}Be aware that targeting given browsers with feature queries is still a hack, because the browsers improve their engines continuously, and these properties can be supported or not in the future.
