Blogger is a free web-based service that allows people to easily create and maintain their own blogs as well as interact with other people on their blogs. In the past, at least a basic knowledge of HTML was required if you wanted to edit your blog. However, Blogger has a new interface that is simple, interactive and doesn't require any knowledge of HTML to use. With a few fast clicks you can change the entire layout of your blog, rearrange text elements or edit your header size.
Go to "www.blogger.com" and sign into your account.
Choose which blog you would like to edit (if you have more than one) from under the "Manage Blogs" header, and click "View Blog".
Select "Design" from the right side of the bar at the top of the page.
Click on "Template Designer" near the upper left side of the page under the "Design" tab.
Select "Advanced" from the tab options on the left side of the screen.
Scroll through the options and choose the element you wish to change. It is listed as "Blog Title."
Choose the font size that you would like the header to be from the drop-down menu. You can also change the header font and the color of the header font here.
Click "Expand Preview" to get a better look at the changes to the header you have made.
Click "Show Controls" at the top of the page to shrink the preview again. If you aren't satisfied with the font size, style, or color yet, then continue to edit them.
Click the orange button labeled "APPLY TO BLOG" on the top right corner of the screen when you are pleased with the appearance of the header.
