Rebuild - new design of my website - tomcat, java, jquery, ajax, and html

Need to change design to a more modern design and build the new html with bootstrap and jquery.

Website url is: http://www.rabbitseo.com

Website account url for example is: https://www.rabbitseo.com/loginGuest?action=login&loginAttempt=1&email=Ronchuke%40gmail.com&password=123&rememberMe=true&__checkbox_rememberMe=true

I will provide with urls to get data in json format, and you need to have AJAX call to to get that url and place the data in the html you create

The charts do not need to be changed.

The target is to have a better view with the current data and functionality.
