Post Excerpt Block
The Post Excerpt Block allows you to display a Post’s excerpt.
Once you've added your Block, there are further options available in the Settings Sidebar. You can change the size of the text using the Font size dropdown or the Custom number field next to it. You can also change the text and background colors.
To add a “read more” link, click the Add “read more” link text placeholder and then type in the text you want to display. You can use the Show link on a new line switch to either show the “read more” link to the right of the excerpt content, or on a new line. If you don’t add any text to the “read more” link field, then no “read more” link will be shown.
