How to number comments in Blogger/BlogSpot

This cool Blogger trick will help you to add comment count inside a speech bubble, so that you & your readers can use the numbers to mention or point to a particular comment on any of your posts. Besides this, numbering your comments might help you to improve the look and feel of your blog.

Note: This works with the previous blogger commenting system, so if you want to apply this trick, first you need to remove the Blogger threaded comments. See here How to remove Blogger threaded comments
UPDATE! Now you can have a comment bubble in your threaded comments also! For more info, please read this tutorial: How to Add Numbered Comments In Threaded Comments

Note:

Comment Bubbles 

To choose a comment bubble, right-click on the image and select "Copy Image Address/Location":



IMPORTANT: You can use any image instead of the one linked in the code above (STEP 8) but after you need to change the size values (width and height), so that the numbers inside the bubble won't float outside of it.

Step 9. Save the template and enjoy your comments :]
