Unlock Hidden Gems: Insider Secrets in WordPress 6.8 for Developers
Style Book sections and more

One of the biggest improvements in 6.8 is the interface update to the Style Book, which separates your style settings into sections. Shown in the screenshot above, you can see how selecting a typeset makes it easier to test and preview your site’s typography.
There are also a couple of other notable upgrades to the Style Book. It now has its own route, which lets you link directly to it. The new URL path is /wp-admin/site-editor.php?p=%2Fstyles&preview=stylebook
. Additionally, Style Book support was added for classic themes.
