Blogger custom layout get post initial text

Question

I was creating a blogger theme and I intend to have a card layout with the first image and a text-only summary (fixed characters followed by ...) in the post list.

I could get the first image of the post using data:post.firstImageUrl attribute. But couldn't find how I can get only a short text out of the post body.

Could somebody help?

Found the answer from a related question How to increase character lengh in blogger snippet instead of using limited length, 'data:post.snippet'?.

The issue was solved using data:post.snippet/ and data:post.longSnippet/.

Thanks.
