homepage .aspx style to change using .ai file

I have a web application written in c#.net for which I have to change completely the design of the page. Actually I have just the .ai file about the new design of the homepage. So with this project Iwant to change the entire design of the .aspx file about homepage, where I have many data loaded from a mssql database, google maps included and some markers selected from database and shown on the map. You should extract the icons and the html from the .ai file and modify the homepage. Also, the homepage must became responsive because actually it isn't.
