7,357 PointsWhen to use a wrapper or container?
I've been looking around on when to use a wrapper or container, but it doesn't really make sense to me. I've been looking at source code now for awhile, but it seems that people use them in different places, if at all.
So my ultimate question is when should I be using a container and where should I be putting it in my HTML?

Containers have broad uses and are great for separation of elements or groups of elements. Technically all the elements themselves are in-a-way their own container for your text or images. Most uses of for containers are for alignment purposes of your page, like Jamie said. You can use 1 "container" to wrap up your whole page in that would share the same CSS properties. Example: Maybe for your page you have just a navigation at the very top and a main body(very simple example). Lets say the navigation you want an image to start from the left side of the browser window and stretch the entire length. But the main body you dont want your text or any elements as close to the border of the browser window. Well you could create a DIV container that you would wrap ONLY around the main body elements and leave the navigation elements above(outside) the container. Then you could apply some CSS styles to it that you would want to flow through the entire main body, such as a Margin of 20px so it would push all text or elements away from the border of the browser window.
This of course is a simplified version of what you can do with it.
