List Formatting

I have been trying to list a bunch contributing writers on my site with their photo next to them. The formatting has been crashing/jumbling into one another and it’s looked really messy.

My I.T friend fixed the issue by adding a bit of additional html. Due to the text editor in WordPress it’s easy to miss/close tags as it all just looks the same apparently. Basically he wrapped each of my writer blocks within a div, with a style that clears it’s element above (in normal language, so they don’t crash into each other / jumble up). Then added p tags with a text align left on the text.

He’s recommended downloading a free text editor if I am to continue to use this theme but I was wondering if this is really necessary given that I have purchased the pro.

Is there an easier way to format lists in this theme to make it more user friendly?

Thanks
