Custom Columns | Cannyon Premium

Hello,

We’re are using the Cannyon premium theme. We have a few video pages and we are trying to figure out the best way to align the body text on the page next to the video, without using a plugin for columns. Here’s one of our webpages: https://dalaigroup.com/maryland-seo/

We have used some basic code on the WordPress page to apply columns, but the margins between the video and the text are too small. I’m very new to code and I am unsure how much I am able to customize on the page itself. What code options might be available to adjust the size of our current columns and their existing margins? Thank you!
