That probably won’t work for Group Headers.
Extra spaces don’t work because web browsers collapse all whitespace down to a single character. If you’re writing HTML directly, you can add a non-blocking space entity (
), but that won’t work in groov. To protect from cross-site scripting attacks, we escape any user-entered input, so you can’t add HTML entities.
Your best bet here is probably to layer a few Line Headers on top of your Group Header; just turn off the underline. That’ll let you match spacing with your gadgets easily, and they’ll scale properly as you resize your browser window. Normal spaces wouldn’t do that.
