Template background colour

Q: How do I add a solid background to the blog title and description?
A: Remove your header image and choose a light colour background:

design>template designer>backgrounds

The permutations are unlimited. No one has been to every corner of the template designer yet. Also, not every choice of template has the same features offered.

You can even decide to change the whole template, just to get some special feature:

design>template designer>templates 

I would suggest starting a test blog and use that for finding your way around your blog:

On your dashboard, click [create a blog]. One Google account is good for 100 blogs

Here are my own test blogs:

Blogging is really a personal journey of discovery. If we only have the help forum, the learning process will become too slow. We will be spending too much time asking questions and waiting for answers on the help forum. This is a slow way of learning. A quicker method is by using a test blog to try out ideas for ourselves. This is especially useful when we go into the the design tab to change the template in 1001 ways and we do not wish to screw up our main blog permanently. A test blog is very expendable. Please try using one or two test blogs.
