Hope that everything is all right with you and your family.
I'm trying to make it so the members of my site can choose a background colour for their topics.
I thought the easiest way is to use BBcode
I tried this
Code
[bground={COLOR}] Topic text [/bground]
Html
<style="background-color: {COLOR}">
You will know by looking at it that it does not work.

What html code would I need to get it to work?
Thanks
Graham
