How to adjust post preview on home page

Hi everyone,

I was trying to arrange the display of post content at home page which is in grid view but its not coming properly. The two-three line from each posts displayed properly but last line at the bottom is half hidden. I tried editing its css but can’t find a way to handle it.

Please look at the category posts at the home page for more details.
