I was looking for something in my style and made an error in tagichat pro..the message box where you type in your message is no longer white and black so you can see what you type. Have tried to find what controls this and going crazy doing so ??
Point being... since it is an add-on, and the styling question you are asking pertains to that add-on, the discussion area that you were pointed to would be the appropriate place to ask the question - since not everybody uses that add-on.
In addition, you need to specify whether you were messing with Style Properties, or in your EXTRA.css.
The code that controls that (for full screen) should be
Been in that all morning..it's one specific edit. It's in box's/ forms like the search box and in message box's. Just don't see what is controlling it. Only happens when you click to write in the box ???
As you found... that controls all the text control related CSS. The code I gave you is the preferred way of changing specific ones in EXTRA.css. You need to use something like Chrome Developer Tools or FireFox's FireBug (or whatever it's called now) to find the appropriate CSS and use it to make your changes. That way it is not applied globally.
