TL;DR:
This update consists of two improvements, the first will provide the option to mark images as decorative (ignored by assistive technology), the second has changed the heading level 1 to be reserved for the page title in the title area only (easier for users of screen readers to understand how your page is structured).  Due early to late September 2023.

Details:
Decorative images are ignored by assistive technology, including screen readers. The new mark as decorative option will be added to the following image types: background image of the Title Region, images added inline with the Text Web Part, Image Web Part, Image Gallery, Hero, Call to Action, and Quick Links.

MS: “To mark an image as decorative, open the property pane details of the web part and scroll to the Accessibility section. Under the alternative text box, a new toggle is available for you to select if the image should be marked as decorative”.

Heading 1 is to be reserved for the page title in the title area, leaving you with heading levels 2-4 for the rest of the page. This makes it easier for users of screen readers to understand how your page is structured.

Tip from Microsoft:  to communicate the heading level of the text correctly to screen reader users, choose a heading style from the text style dropdown menu, instead of just using visual styling such as increasing the font size and applying bold formatting to the text.

  1. Highlight the text you wish to style as a heading.
  2. Open the text style dropdown menu.

 

Availability: 
Due early to late September 2023.
