Adding white background on top of an image

[brian4021]

I'm trying to add a white background to the entire areas that are highlighted in red and still keep the image in the background. I've seen it on another website but can't quite figure out how to do it. Also if someone could tell me how I can remove the text "Categories" that comes default with the Persona theme I'd really appreciate it. Thanks!

Go to http://westsiderpg.com//admin/appearance/customise and place this in the field and hit save.

.categories>li, .category>ul>li {
      background-color: #ff0101;
}

Sweet thanks @MJ

Is it possible I can create another white background behind a user's post as well? cause I'm using a custom background and now the text of the post is not visible anymore.

What you want is actually:

#content {
  background: white;
}

@PitaJ I used what you posted but now the spacing between each header disappeared. I tried margin-top and margin-bottom but nothing. Also could you tell me how I can remove the text "Categories".
