Have you checked your blog lately?
I opened my blog and was so surprised with their new feature! LAYOUT Tab is no more - it was replaced by DESIGN! And design it is.
The new Blogger Template Designer has five templates in varying colors and themes, in different body and footer layouts and - adjustable widths!
If you're not satisfied, they have the advance option for customization, and if it's not still as good as you want it to be, they still have the EDIT HTML link for you to change anything on your blog layout.
I am just FLOORED with this evolution. It's a good thing for most of the bloggers who doesn't know how to change templates because Blogger made it easy for them. It's still good for most advanced bloggers since the possibilities became endless now.
I'm not a professional HTML/CSS editor, but I do know the basics of editing layouts. But in times when I just want to change something or everything in my blog's look without too much fuss, this changes in the Blogger options made it much easier! For that, A LOT OF THANKS Blogger - FINALLY!
