Reduce size of hidden content in a Summary Block

Hi there,

I used some CSS to remove the Categories and reduce the Excerpt length in my Blog Summary blocks, but it seems to have increased the white space underneath the posts. When I used "Inspect" to try see what I could target, the unwanted white space is showing as blue (content), rather than orange or green (white space).

Does anyone know how I can remove the unwanted white space in both my Blog Summaries (the "Sidebar" and the "Related Articles" section)?

See image attached.

Thanks so much!
