my question is very general. Since past Monday, every page on my site if I "edit" the page (regardless of if it is front page or subsite page), the top navigation fonts would change after I press "check in".
I can "edit" a page and dont make any modification but simply press edit page then check in and publish and the font would change.
Is this caused by CSS?
How does the process works? So after I check in the page, a java script or what runs in the background?
Thanks and sorry if I wasn't clear enough.
