Hello snackablesocialmedi,
Thank you for your question on displaying only excerpts for your posts. To do this, you need to add a very small bit of code to your posts. This is known as the ‘more’ tag. This sets a specific point in your post so that anything above it is displayed as the excerpt.
There is a button to add the code in the top of the editor toolbar. It looks like two solid lines with a dotted line in between. After clicking that button an area will appear on the post that is a dotted line with the word ‘More’ in the center.
This is so you can control how much or little you want to display for the excerpt.
Kindest Regards,
Scott M
