I have a “banner” I’d like to include in the OP of a topic, and I’d like it to just take up the full width of the text box rather than shrinking down to the size of a onebox and leaving blank space on either side - what’s the best way to accomplish this?
Bonus points if it can’t be clicked on to pull up a full image like a onebox can, it’s a banner and should ideally not be able to be interacted with.
