Hi there,
There are two ways to remove unused styles from your Webflow site:
The first method is to remove styles individually by clicking the “wrench” icon next to any unused class (those without a “list” icon) in the Style selectors panel, then clicking the “trash” icon to delete it.
For a quicker solution, you can remove all unused styles at once by clicking the “broom” icon in the top right of the Style selectors panel.
Hopefully this helps! If you still need assistance, please reply here so somebody from the community can help.
