DeveloperAdd custom HTML attributes to any block, with optional dynamic variables on the front end.
HTML Attributes Customizer for Blocks adds an HTML attributes panel in the block sidebar. Enter one attribute per line as name="value" (double quotes), or a boolean attribute as a single name (for example inert).
Attributes are stored on the block as JSON objects: htmlbacAttributes and htmlbacInnerAttributes (for example {"fetchpriority":"high","data-nolazy":"0"}). Boolean flags use true.
Merging: Duplicate names on multiple lines are combined. Values merge with spaces (semicolons for style). class merges with the block’s existing classes instead of replacing them.
Variables: Use tokens such as {{post.title}} or {{user.auth_status}} inside quoted values. They are replaced when the block renders on the front end.
