Blogger Free Template

For color and the font size, some Blogger templates offer an option to change it from the Dashboard (Dashboard → Layout → Fonts and Colors). Here you can see the result directly in the template.

Major changes in the templates needed to know at least a little CSS and HTML. A quick way to modify a template is change the images in the CSS code, for others with the same dimensions. That is the process to change the header of a design, for example.

Additionally, some templates have their own settings instructions and customization, refer to the same download page of your template.
