Excerpts on Home Page - how to get them to appear like the example

This may be a very ABC question but I would like to know how to get my home page to appear like the example with the excerpts “Continue Reading” and the posts below to show an excerpt. https://colorlib.com/wp/themes/blaskan/.

I also imagine there must be a cut-off point to how many post show on the home page?

My site is not launched as I would like to figure this out 1st.

Thank you in advance for any help in fixing this issue.

PS I know this is not a theme issue, but rather my lack of understanding how this works:)

Hello,

I hope you are doing well today.

You need to edit the post or page then on the upper right hand side there would be “Screen Options”, so go there and enable the checkbox for “Excerpts”. This will add an excerpts field to be used for excerpts.

Best Regards,
