I am using Twenty twelve theme.My website http://www.llewellynlee.com hosted on FatCow
I was trying to learn how to increase size of font on my blog.
In WordPress editor I selected appearance and then css.
I found myself on css editor page
at top of page it gave me Beginner tutorial
I selected it and went in and out of the tutorial several times
But did not make any entries or put anything in the editor page.
Finally with so much to learn I decided to leave it to next day.
Just for the joy of it I went to look at my site early next morning.
All pages had no left margin (the edge of the paper was right by the text). I logged in to check my site and found that somehow I had created 6 css revisions on the 25 April.
I assume that is why cut off my page edge.
where do I look to find and delete those css entries.
They are all listed in right side of css editor page so I hope there is a way to select and delete them
Thanks for help
