Image poster block align text to top

Site URL: https://www.theemailschool.com/community

Is it possible to align to the top text in the image poster block? Right now it's centred. I used shift + enter to move text up but it doesn't work always.  Ideally if I could change the padding and first line is at the same height in every image block. I have multiple pages of the same image blocks. 

Image in the attachment. It's Squarespace 7.0 Brine.

Perfect. Thank you.
