CSS / Performance
While auditing a site's global CSS, every anchor tag was set to transition eleven properties including `filter` and `backdrop-filter`. On hover, only `color` and `opacity` changed. The two filter properties were dead weight — composite-layer hints the browser never needed.
Listing `filter` and `backdrop-filter` in a global `transition-property` rule tells the browser to watch every covered element for changes to those properties — even when nothing ever transitions them. Scope `transition-property` to only the properties that actually change.
Task
Remove `filter` and `backdrop-filter` from the `transition-property` list. The hover state only changes `color` and `opacity` — those are the only properties worth watching.
