How do I add padding so that there is more space between Categories & Name? The categories is in the rich text widget and the “name” is within the blog comment form widget, but they’re too close to one another. 
Heather,
You can put a root class around the two widgets, the Rich Text and the Blog Comment form, and then use one, or both, classes to add margin through CSS. Say you put a root class of “blog-comments” around the blog comment widget, you could then define some CSS as follows:
.blog-comments { margin-top: 20px; }
In addition, you can inspect, or view source on the Blog Comment form and see the built-in classes, and HTML elements used for you to style the form itself.
