How to add a custom background to my Q&A?

You can upload your own background for your Q&A session.

This requires that you modify the theme CSS. To do so, follow the below instructions:

1. Upload the desired background image in your workspace, via Content > Files > Live Resources. The image should have a 16:9 ratio, ideally with a 1920x1080 pixel resolution, and in JPG format.
2. Go to Live > Q&A > Preferences > Themes, click on the + sign at the bottom of the left side bar to add a new theme.
3. This will display the CSS code. To ensure your uploaded background image is used, replace the following part of the code:

html {
    min-height: 100%;
    background-image: url(../../live-resource.background2/file.jpg);
    background-size: cover;
    background-repeat: no-repeat;
} 
body {
    background: transparent;
}
div.live-comment-list {
  position: absolute;
  left: 0;
  top: 0;
  padding: 0 1.25rem 0 1.25rem;
  width: 100%;
  overflow: hidden;
/*  background: url(../../live-resource.background2/file.jpg);*/
  /*background: -webkit-linear-gradient(left, #CF532E, #E87330, #CF532E);*/
}

Important: In the code you added, make sure that in the line:
background-image: url(../../live-resource. background2/file.jpg) AND
/*   background: url(../../live-resource. background2/file.jpg);*/,
"background2" equals the name of the background image you have uploaded in the live resources:
