spacing issue with two archives

I want to run both ELA and Timeline archives on my website https://www.rebeccawright.com as seen here https://www.asceticmonk.com/blog/?page_id=340 but not being very good at html or css I’m not sure what to add so I have the correct spacing between the two archives, so that the timeline archives sits nicely below ELA in all browsers. Can anyone help out? Thanks much!
