118: Aaron Gustafson - Semantic HTML: The Hard Parts

Full Stack Radio

In this episode, Adam talks to Aaron Gustafson about authoring semantic HTML in the context of web applications, where choosing the right element can be a lot more complicated than it seems.

Topics include:

  • Can you have more than one "h2" on page?
  • How important is heading order?
  • Why not everything that looks like a heading should necessarily be a heading
  • Why you may want to include invisible headings in some situations
  • What the document outline is and how your use of headings impacts it
  • How to make your heading levels dynamic to make your components more flexible
  • What a "sectioning context" is
  • Can you have multiple "article" elements on one page?
  • What even is an "article" anyways?
  • How to use elements like "section" and "aside" properly
  • Should navigation items be in lists?
  • Why Aaron can't remember the last time he used a "span"
