Unfortunately, I’m a bit of a CSS novice. I understand what it is, and what it does, but I’m not good at implementing it.
If you head over to http://thomasrbarron.wordpress.com – you’ll see that I’m using the Columnist theme. You’ll also see my name (Tom Barron), listed on the right hand side as the Site Title. If you were to click on a Post, you’ll find that similarly to the Site Title, titles are collapsed or ‘stacked’ word by word in that invisible column. Is there a way to widen the column to an extent with CSS?
Yes, it’s possible, but I don’t think it’s the best option (if by widening you mean move the main column to the right). If the left column included widgets, it would be fine; but since there’s only a small image and a title, the empty space will become too wide in my opinion. What I would suggest is remove the excessive padding, so that the titles can take up more horizontal space, and decrease the size of the post titles. Try adding this in the CSS editor and see if you like the result:
