Archive Title Block
The Archive Title Block will display the name of the Category, Tag or other Taxonomy, on your theme’s archive pages. Although you can add this block into your normal Page or Post content, it will be more useful adding it to your theme’s templates using the Full Site Editor.
Once you've added the block, there are further options available in the Settings Sidebar. You can change the Text and Background colours, and various Typography settings like Font size, Appearance, Letter case, Line height & Letter spacing. You can also select the heading level (H1-H6) for the title using the Block Toolbar.
The various options for this block are located within separate Settings () and Styles () tabs, in the Settings Sidebar.
