For V2 Headline elements, there’s currently no option to inherit the font size from the theme stylesheet. Instead, each H1, H2, etc… needs to be set manually. This is extremely frustrating and I don’t understand why you designed it this way. I’ve never seen this approach used in any other theme and it makes no sense. The whole point of applying CSS to headline tags is to be able to globally adjust the headline sizes. With the V2 Headline elements, if you later decide you want to change the font size for H1, you’d have to manually update every single H1 on the site. This is crazy!
I’ve seen tons of other users complaining about this issue on the forum and it seems your standard reply is to advise people to use presets. Well, presets are great, but they don’t update the applied elements globally, so if you apply the same preset to all your H1 elements and then later want to change the font size, you’d still have to go through and update every H1 manually.
I know how to write CSS and of course I could create a custom stylesheet, but then I’d have to create a separate class for each headline element, like .h1-custom, because if you use the built-in classes, your CSS will be overridden by the element-level CSS, which means you’d have to use !important tags, which would then make it impossible to set the font size at the element level. Again, this is nuts! I don’t want to have to manually apply a custom CSS class every time I create a headline element. The page builder is supposed to make your life easier, not harder.
There’s an extremely simple solution, which I’m sure your development team could implement in about 15 minutes. In the Text Format section, where you specify your font size, simply add an “Inherit” option to the units selector. So the user would click on the PX or EM button and in the popup list, there would be an option for “Inherit”. This would work exactly the same way that the margin settings work, where you can select Auto instead of entering a unit for your margins. The Inherit option should be the default and once it’s selected, the font size would automatically be inherited from the theme style sheet.
