XML - Creating and Customizing 'Frames'

[Gillymead]

Hi,

I'm completely new to creating anything with LUA and XML. I have some JavaScript/CSS/HTML experience but that's about it. Apologies if this post is in the wrong place or I've missed similar threads.

I followed the MyFirstAddon tutorial, which was quite useful, and decided I'd start trying to 'skin up' the frame for the content a bit more. Presumably the inherits="ZO_ThinBackdrop" attribute is controlling the current look/style of the frame the counter appears in, as well as mouse actions against it?

Anyway, I've been trying to do something really simple, change the colour and alpha of the background of the frame, but failing pretty miserably.

Think I tried using an attribute of centerColor="990000" or something similar to add a dark red background, but didn't seem to get anywhere. I played around with a couple of other things too.

Can anyone give me a starter for ten here?

Cheers,
Gillymead
