Upfront, before anyone asks: yes, I've googled this and I've read every single article on every dodgy blog site instructing me to:
- Create a CSS file and drop in the Style Library.
- Write some CSS with .ms-rteStyle-whatever and/or .ms-rteElement-whatever.
- Reference it in my master page.
- Check in and publish all the things.
Also, I've already seen this question and subsequent comment, and I'm not using a custom new or edit form. Just a custom list with an enhanced rich text site column.
The advertised method for adding custom styles works great... for wiki content on pages. Unfortunately, that's not what I need. I need to be able to offer these custom style options in an enhanced rich text column on a custom list. Anyone know what I'm doing wrong, or what I need to do?
