For example, I'm making a website with width of 960px. How should I use the container of this width? Are there any rules about it?
.container {
width: 960px;
margin: 0 auto;
}
What is more correct?
1) <div class='container'>[whole website]</div>
2) <div id='menu/header/etc'><div class='container'>[content for this block]</div></div>
3) <div id='menu/header/etc' class='container'>[content for this block]</div>
