userChrome.css to disable blue highlight marker on active tab

more options

I am using tab-on-bottom code in userChrome.css that I got from the web.

1. There is a highlight feature of the tabs. A mouse-over will do a subtle enhancement of the top portion of the line delineating of the tab. 2. The active tab has a blue bar at the top portion of the line delineating the tab.

I want both to go away. I have code to highlight the background color of the active tab and need no other highlight function.

The userChrome.css is below.

Thanks, Gert

Hi Gert, you can put <pre> before and </pre> after blocks of CSS here to avoid interpretation as wiki markup.

The selector for the line at the top of each tab is very sensibly named: .tab-line

To suppress that you could try either:

.tab-line { opacity: 0 !important; } .tab-line { background-color: transparent !important; }

Was that it?

Yes, both work.

Just wondering, is there a comprehensive list of UI objects with tutorial how to control them?

Cheers, Gert

There's definitely nothing official, and things change often, so any list would age rapidly. You could do what many people do and become comfortable poking around using the Browser Toolbox. https://developer.mozilla.org/docs/Tools/Browser_Toolbox
