Maybe you don't want to go to the trouble of making your own styles, and you just want some ready-made styles that allow you more flexibility than what's available in the Rich Content Editor.

You can find some ideas in the Canvas Style Guide: yourdomain.instructure.com/styleguide

Here's a fun list style, the horizontal definition list, available in the style guide (this example is taken directly from the style guide):

Acid: A substance that produces H+(aq) ions in aqueous solution
Acid Anhydride: The oxide of a nonmetal that reacts with water to form an acid
Acid Anhydride: Compound produced by dehydration of a carbonic acid

<dl class="dl-horizontal">
  <dt>Acid</dt>
    <dd>A substance that produces H+(aq) ions in aqueous solution</dd>
  <dt>Acid Anhydride</dt>
    <dd>The oxide of a nonmetal that reacts with water to form an acid</dd>
  <dt>Acid Anhydride</dt>
    <dd>Compound produced by dehydration of a carbonic acid</dd>
</dl>
