Edit CSS filters
filter property in CSS lets you change the way a particular element gets rendered.
Firefox provides a visual editor to play with CSS filters. You can add or remove filter functions from the list, re-order them, edit individual functions and even create presets that you can reuse later.
- In the Rules panel, find an existing
filterproperty, or add a new one.
- Click on the filter swatch icon next to the filter value.
