In RH 2020 I have created a new skin based on Azure_Blue. I want to be able to change the size of the title style contained in the Header section (i.e. not in a topic). I can see how to change the background colour, font colour, but not the font size. How can I do this in the project please? I can only find the style rule in the layout.css file in the output folder (body.media-desktop div.header div.title), but I'm assuming that there must be some way to set the size in the project itself?
There's nowhere in the user interface to change that, as far as I'm aware. You could change it in the layout.css, but I'm not sure if that file gets overwritten by Adobe during updates, or not.
If you're concerned about losing changes in the layout.css, you'll need to add that style into a custom css file and add the css file into Layout > User Assets in the skin.
Frameless skins have more customisation options, but do be aware that if you use context sensitive help calls in your application, your developers will need to make a couple of changes to how they call the help.
