Blog carousel posts in home

I would like to have differents posts caroussel and show some extracts, not all the text, as you can see I have some problems in my home some posts show all text and it is not very nice… what I have to do ?
Thanks a lot for your help.

Hey Sandra,

I see that you already have equal heights enabled which makes each block line up nicely even if the length of the contents are different, however, if you want more control over the length you can use this:

function my_excerpt_length($length) {
  return 20; // Change to your desired length
add_filter('excerpt_length', 'my_excerpt_length');

Put it in your functions.php file found in Appearance > Editor > Theme Functions.
