Excerpt options control how post excerpt is displayed. Usually news websites don't show excerpts on pages, but there's an option to do it, so it's on you.
- Show excerpt - If checked, this option will make a heading in one row and hide the overflow. Three dots will appear at the end of line.
- Excerpt length - This number defines the excerpt length. Excerpt is actually the post content that appears below the heading. This figure sets the words length of it.
