HTML <aside> tag

Updated: 02/04/2024 by Computer Hope

When writing in HTML (hypertext markup language), the <aside> tag is a block element describing a section of content that only partially relates to the content near it. Additionally, anything inside the <aside> tag could be considered separate from said content. Examples are sidebars, related advertisements, and links to similar articles. The following sections contain information about this tag, including an example of it in use and related attributes and browser compatibility.

Example code

<p>Computer Hope is a website that offers free help and support.</p>

  <b>Fun Fact:</b><br>
