You've probably seen people with backgrounds in their backstory (not detailed backgrounds. Just solid color backgrounds). You may be wondering how to do it. Here's the code

<*blockquote style="background-color: color;"*>

Click Tools. Then click Source Code. Paste this code in Source Code. Replace color with your choice of color. Then remove the *. This is what you should get...

<blockquote style="background-color: green;">

click save at the bottom right hand corner, and you'll see your backstory now has a background.
