Post Excerpt Block
The Post Excerpt Block allows you to display a Post’s excerpt. The excerpt is a small paragraph or two that provides an introduction to your content. It’s typically the first paragraph or two of your blog Post, but you can also create custom excerpts using the Excerpt panel in the Settings Sidebar, under the Post tab, when editing your individual posts. Although you can add this block into your normal Post content, it will be more useful once you can edit your Theme’s templates.
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.
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 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.
