Story behind this pen
My friend
Mr. Dhanush Badge
has sent a mail mentioning
Stackoveflow.com
link where one of user has posted question regarding animated border only with CSS.
At initial stage i have replied his mail saying:
"Need to think in deep and It would be fun to do this without image ..... but
HOW
is the question.."
After lot of thoughts and recoding somewhat i am able to come up with this solution.
This is purely base on
:before
and
:after
selectors with animation.
Please take a look and it can be imporved further.
You need to change value of width and height into animation scipt compare to your box size.
It will help someone if need to highlight section with animated border.
