How to remove border bottom for h1 and h2?

[pythoninja]

I want to remove the underline after the h1 and h2 headers. Is that possible with, maybe, custom CSS?

Hi, good idea, that line is not to everyone's taste. I have added a setting for it: Settings > Markdown > Heading underline. It is on by default, and turning it off removes the line under the level 1 and level 2 headings of Markdown notes, in the preview as well as in the editor's live rendering. It is a per-account setting and it will be available in the next release.

In the meantime, custom CSS does work if you are an administrator of your instance. Save the rule below in a .css file, upload it in Settings > Admin Tools > Custom CSS path, select it and save. Note that this applies to every user of the instance.

.markdown-preview h1, .markdown-preview h2, .markdown-editor .cm-live-preview .cm-line { border-bottom: none !important; }
