Site Title Block
The Site Title Block allows you to add or update the title for your site. Although you can add this block into your normal Page or Post content, it will be more useful once you can edit your Theme’s templates. The Site Title will link to your site’s homepage but you can remove this link using the Make title link to home switch.
The site title is typically the name of your site. The title is quite often displayed in the site header if you haven’t uploaded a site logo, but that depends entirely on your theme. The title will also be used for SEO purposes and can be displayed in search results or on the browsers tab. The Site Title can also be changed on the Settings > General page.
Once you've added your Block, there are further options available in the Settings Sidebar. You can change the Text and Background colours, and you can also change various Typography settings like Font size, Appearance, Line height, Letter case & Letter spacing.
