Q1 : How do you manage the complete site in center of the browser, which is completely using divs using the help of css2 or css3?
In CSS file
1. body{width:100%;}
2. Create a div tag and assign a class, say 'container' and place all your content in this div tag.
3. Assign properties to this class in CSS file
container{width:777px; margin:auto;}
Note: "margin:auto" will place your page in center of the page.
