@Aizada_M I’m not sure if this helps, but you can use this…
https://github.com/merefield/discourse-tc-coloured-text
It gives you a button in the Composer to decorate selected text with different colors and background colors… the code it generates in the composer looks like this…
[wrap=yellow color=green bgcolor=red]
[quote="system, post:1, topic:3, full:true"]Create topics here that don’t fit into any other existing category.[/quote]
[/wrap]
[wrap=yellow color=green bgcolor=red]Create topics here that don’t fit into any other existing category.[/wrap]
(Not sure what the “wrap=color” does though)
If you want to set the background color for all quote blocks on your site you can use this CSS…
aside.quote .title,
blockquote {
background-color: yellow;
}
