Yesterday, I spend some to change the blog template using Bootstrap.
Thanks to Blogger's new template editor. Now it is much easier to understand the templates.
The template was built on top of my older template Simple by Joshua Peterson. The process was simple and straight forward.
Blogger templates are mostly collection of widgets. I introduced few new divs with Bootstrap classes and removed few divs from older template. Bootstrap documentation has everything clearly explained along with examples.
I haven't tested this new template on all screens yet.
