<div> elements given a class="wrapper"
What is the semantic meaning behind a "wrapper", and what are the more practical examples of using a "wrapper" with HTML?

Of course it can refer to a number of things, but I would point 2 of those:
- In general, it means a larger unit which "wraps" smaller units together, so that certain properties can be applied
- And most importantly, it "wraps" together elements in a way that their positioning will be determined by it. (Usually groups them closer together.)
An example is the menu here on Treehouse. The gray color background of the menu is an element which is responsible for the background color and vertical width of the menu. The wrapper element is responsible for the position of the elements, which are not spreading as wide as the background color.
I've made a demonstration of this for you, check out this picture:
