Ready to get experience with this new fonts choice? Simply go into the Advanced tab of the Blogger Template Designer for your blog, select the type of text you’d like to change (Post Title, Blog Title, etc.) and click on any of the new Web Fonts for a preview. Don’t worry, nothing will change on your blog until you select “Apply to Blog”, and this means you can play around with all of the fonts and only make the switch when you’re ready.
If you use customized template, you can use this various font from Google fonts directory. Read the installation setting.
