Isn't important meant to be a last resort?
Some work with important. The only problem with this is (for example: I set a{size:16px !important} now this applies to all links including readmore, view online, headings e.t.c. and it becomes harder to correct those. Secondly it now becomes impossible to set the size of links in a paragraph since (I noticed) this can only be done in the <span> added to the content in paragraphs that are styled different from the template's default.
Another major issue is that my edits in CSS don't show in the preview window beside the drag and drop editor unless I click the apply button which takes me to the window with "Edit Template" at the top of the template view. So its hard to know what works and what doesn't.
Thirdly, I tried make my css modifications in the "Advanced Options > Add custom style sheet" since the "Edit Template" page doesn't preview lots of the custom css but I am having this issue where when I input custom css it behaves erratically. Sometimes it clears the whole content of the code i entered, other times it doesn't save what I typed, other times it reverts to an older code.
