I want to remove the whole banner from the bottom of the HTML5 output (desktop-size view) that contains the "Go to top" button. I've tried looking around in the CSS file of my layout, but couldn't find how to change it (I can remove the image, but then I'm still left with a blank white bar along the bottom of the screen).
Is there a way to set the size of this using CSS somehow?
You can remove this. But you'll want to go to the SCSS source files to make it easier on yourself.
Search for a.to_top. You'll need the second occurrence in the Desktop layout. If you remove the code completely, it will be gone. Then amend the height of the topic to take in the available space freed up by removing the button.
Thanks William. I'd figured out how to remove the button, but I hadn't changed the topic height.
If I edit the height of body.media-desktop div.topic iframe.topic it now works fine.
