How to Display Author Name and Number of Posts Written in Blogger/blogspot Blogs

In WordPress you can show number of posts written by an author, you can do this even in Blogger, but you need Java script to do that.

Showing author name and number of post he/she has written on the blog is useful for multi author blogs. As multi author blogs proudly display their number of authors and post count to the public.

The Java script code we are using here can also be used on single author blogs.

Installation is pretty simple, add the HTML/Javascript gadget to your blog and paste the code there.

<style type="text/css">
.author-line     {margin: 3px 0;}
.author-avatar   {vertical-align:middle;}
</style>
<script type="text/javascript">

// CONFIG:
var maxUserNameLength = 42; // 0: don't cut, >4: cut usernames
