  Its very frustrating to get error message for password after signing up "and after waiting for 3-4 sec for ending pre-loader "

Closes: #126 #127

Describe the changes you've made

I had added the java script for these validations and some CSS for its cool display.
It is looking like this.

I had corrected the spelling mistake changed "forget" to "forgot"
