I'm working on my admin area theme and I wanted to make some modifications on the way the thickbox and tinyMCE looks. I could make most of the changes through adding custom stylesheets and JS to my admin area using
wp_enqueue_style() but I have had a hard time making some others changes. This is because the iframes containing the elements are either not reachable by my own styles or have in their head some other stylesheet and JS that override mine.
!important declaration but I was wondering if there was any hooks that would allow me to call
wp_enqueue_style() to put my scripts inside those iframes headers? Some hook similar to
admin_init but for the thickbox or iframes?
