Add Blockquote with auto line numbering

Add Blockquote with auto line numbering
blog code

We know that blockquote is widely used in various blogs and websites. But sometime blogger failed to explain to visitors because of absence of line number. If we can add line number in all shared code then we can indicate the specific line to visitors if they made query. Suppose a user face problem in 22nd line of the shared code but due to absence of line number user have to share the line in comment box but in comment box all the code doesn't support for resisting spam. So if we can add the line number then we can easily refer them that change or alter on specific line.

You would be aware about Blogger new HTML editor that they have added this feature. As a result now we can easily identify the specific line. So I have tried to add this in blockquote. Actually this code build with pure CSS and very easy to add into your blog. So let's proceed to the tutorial.
