Styling Quick Launch with CSS breaks my top navigation.

[Deleted]

Hi!  In SharePoint 2013 we have react components for our top menu.  The problem is when I use CSS to style the quick launch the react components disappear. What could be the problem?

Could you provide a bit more information? Have you opened up dev tools in the browser (F12) to see if there are any errors being thrown by the React Menu?

I believe your branding css overwriting top navigation, opened up dev tools in the browser (F12) and try to see which CSS class have an issue, try to debug one by one. you can remove CSS class from browser and see which CSS class or property giving issue
