We have already coded a web site html & css by using bootstrap. All parts are well coded.
We need some arrangements on the design (padding, margins etc...) It will be an easy job if you are familiar to bootstrap.
We will need to work on IM, so I will say you what do do and you will do the arrangement.
Output must be the same for Chrome, IE , firefox and mobile browsers.
Please ask the web site on PM before you bid.
