This is in normal flow

The boxes go all the way to the right; new things either go to right (if inline) or below (if block). Thesis Parade...

Here is some text that's long enough to do something when browser size is changed.

And more text, back to same position.

This paragraph will be here no matter what.

Floating elements are fun to deal with.

Another floating element. See what fun? Although more annoying, floating elements are more general than using the inline-block attribute. I hope you are looking at examples in the textbook!

Yet a third floating element. We now seem to have made 3 columns!

A fourth column, as long as the window is wide enough!

This is probably not where you want it! You will use fixed width and liquid layouts for your projects; see many more examples in the book.
