UI fixes afer homepage updates (#289)

This PR fixes a few issues across docs from recent home page updates:

- restores margin above the `.content` element and `h1` to preserve
whitespace between breadcrumbs and page content
- restores margins for all headers
- removes `height` property from labels to center-align text vertically
- comments out properties in labels that have no effect
- updates border-radius for pseudo-class labels to match other labels
