Are you a theme, plugin or framework developer for WordPress? Take note: the heading structure in the Admin screens will change in WordPress 4.3.
From H2 to H1
Currently, in WordPress 4.2 and before, the main heading in admin screens is an
<h2>. However, if you want to have a correct, semantic heading structure, a page should an
<h1>, but only one, which describes what the page is about.
People using assistive technology use the
<h1> to identify a page and quickly know where they are. Further, proper HTML5 dictates that an
<h1> should be the initial heading.
Therefore, in WordPress 4.3 the headings of all admin screens have been changed from
<h1> (see #31650).
Related CSS changes
If your theme or plugin still uses
<h2> for admin screens, don’t worry; styles for
<h2> are still supported in the admin CSS so that, visually, nothing changes during the update to 4.3. However, a new class was introduced to properly style
page-title-action. Here’s an example of the new class in use:
<h1>Posts <a href="[..]/wp-admin/post-new.php" class="page-title-action">Add New</a></h1>
The old class
.wrap .add-new-h2 is still supported but has been labeled deprecated. It has been replaced by:
More changes ahead
After the release of WordPress 4.3, the accessibility team will continue making changes to heading so that they are semantically correct. Current
<h3>s will become
<h4>s will become
<h3>s, and so on.
Check your code
Does your plugin, theme, or framework have admin screens? Check the heading structure. Change the main heading from an
<h2> into an
<h1>. If you’re feeling generous, check the rest of your heading structure to ensure it’s semantic.
Making these semantic changes will ensure your plugin or theme is in sync with WordPress and that people using a screen reader can understand your admin screens better.
