The Aside Post Format is designed to be used as a “Side Note” or a short paragraph. Although the Aside Post Format is designed to be used when writing a single paragraph, it could also be used for a couple short paragraphs. As you can see here, the Aside Post Format for the HavaWebsite Theme is designed to look like a sheet of notebook paper.
 
When this post format is used, depending on the font styles, the line height might need to be adjusted. Change the font size and line height in order to make this post type work for you. If you don’t want to see a break in the paper, use a space instead of a return in the WordPress text editor.
