But it would be awesome if the developers could implement this small feature in forum update.

Thanks again 🙂 

you can add the Post ID

example Post ID 14

#wpforo #wpforo-wrap #post-14 .wpf-spoiler-wrap .wpf-spoiler-title {
color: #ff0000;
}
#wpforo #wpforo-wrap #post-14 .wpf-spoiler-wrap:nth-of-type(2n) .wpf-spoiler-title {
color: #ff9900;
}
#wpforo #wpforo-wrap #post-14 .wpf-spoiler-wrap:nth-of-type(3n) .wpf-spoiler-title {
color: #17a2b8;
}

That's a nice workaround. But there's a problem, Suppose I create an another topic in forums and need different colour on second spoiler and if I change it in custom css, then all the spoilers in other topics will also change.

#wpforo #wpforo-wrap .wpf-spoiler-wrap .wpf-spoiler-title {
 color: #ff0000;
}
#wpforo #wpforo-wrap .wpf-spoiler-wrap:nth-of-type(2n) .wpf-spoiler-title {
 color: #ff9900;
}
#wpforo #wpforo-wrap .wpf-spoiler-wrap:nth-of-type(3n) .wpf-spoiler-title {
 color: #17a2b8;
}

It worked flawlessly, But what if we want to change the colour of 3 spoilers in a post with different different colours ?

Example 😉 

#wpforo #wpforo-wrap .wpf-spoiler-wrap .wpf-spoiler-title {
  color: #ff0000;
}

As the topic says, How can we change the colour of a Spoiler Title ? 

For Example :

This is an example

How to change the colour of Spoiler Title Hello, Because If we change it with the formatting buttons, the whole Spoiler section gets hidden.

Thank You.
