Adding a background

I got a background from http://blogspottemplates.blogspot.com/.

I downloaded the template as a zip file that contained two text files. The one text file was a readme and the other contained the coding.

I logged into my account and clicked on Design > Edit html

I then clicked the link that said choose file and chose the text file containing code.

Then I clicked Upload and blogger uploaded the code into the text box for me.

Clicked Save Template and Voila! Background appplied.
