HR Height not matching the markdown preview

Question

Apologies if this is a dupe, I couldn't find it.

The <hr> styling for the preview and the actual posts doesn't quite match up, there's an extra style affecting the preview:

form hr{border:1px solid #ccc;width:100%;text-align:left;}

This makes the preview look like this:

And the actual look like this:

The actual is a nice clean 1px line, but due to the form hr rule overriding the border: 0 hr rule in the preview, it doesn't look quite right.

Answer 1

Good catch -- this was some old useless CSS rule. Removed.
