Tabs Style

Here's a tab style I created for a recent project. There's a basic IX2.0 hover color change on the tab menu items, however I can't (without custom code) style the prefix text when a tab is active. I know it's a simple CSS line in some custom code, but was wondering if anyone knew of a Webflow way to do it! The lack of .parent .child { css:rues; } in Webflow is a bit of a pain!
