Applying changes to ALL pages

It’s not always working for all elements across different pages, because template developers are using different tag names and classes for same elements but on different pages. Post page can be built differently than home page so if you’ve picked an element on home page the CSS rule automatically created for it might not be applied to this element in different template. So it all depends on how the template was built.

You’ll have to go to the page where the customization is not working, select the preset which was set up for this element and use a button to add another element to current preset and click on this element. Then save changes.
