Adding any HTML code in Extra bio field adds long horizontal scroll bar at bottom of my pet's page.

I am trying to dress up my kitty's page by adding some HTML using guides I have found on Catster. The problem I am running into is that everything I add in the Extra bio field that has HTML code in it adds a long horizontal scroll bar at the bottom of my kitty's page.

At first I thought it might have been something erroneous in my CSS coding, but if I delete everything and just put the word 'test' in SPAN tags, I am able to reproduce the issue. Looking at other pet pages which have been customized, I am seeing it on those too.

Examples:
www.catster.com
www.dogster.com
www.catster.com
www.dogster.com
www.catster.com
www.dogster.com

I am seeing this in both Internet Explorer and Firefox on my pc, as well as on Safari on my tablet.

Is this a bug with Catster/Dogster pages? Any idea on how to go about getting this fixed?

Thanks!
