By default, the Simple block, Columns, and Section components create <div> elements in the published page.
Users can select a different HTML element to use instead of <div>, to use as a page landmark. Page landmarks allow screen readers to more easily navigate a website, improving accessibility.
For example, users can add a Simple block, configure it as a <nav> element, then add a Table of contents component inside.
The HTML Tag dropdown menu is available under the Settings menu of the components.
The semantic HTML elements to choose from are:
<header><nav><main><section><aside><form><footer>
