Space for text on Profile

I did some customization on our camera club site (naplescameraclub.com) 6-8 years ago, but have not made changes in recent years. With the conversion to the new SmugMug, I've been working on the site for the past week, and am just beginning to come out of the fog. The old Bio box and the home page was apparently converted to a Profile. The Description on the page is a full paragraph. The first few days I worded on the site, the full description displayed in the profile block each time the home page was displayed. I must have changed something, as the Profile now only displays two lines of text, near the bottom of the Profile box, and provides a tiny scroll bar to access the rest of the text. What do I need to do to always display the entire description text without scrolling? I've tried adding a block containing Nicholas Shurlock's customization CSS to the page, but it didn't change anything.

Thanks!
