Closing tags and brackets outside of code blocks

From lesson 3 on most if not all of the code examples under the videos have the final closing tag or bracket outside of the code example block. Not a big problem but means when you hit copy that closing tag/bracket doesn't get copied to the clipboard.

Again not a big deal but the introduction to the framework should be a hassle-free experience.

e.g.

Start by reviewing the code examples from lesson 3 onward in the bootcamp videos, focusing on closing tags and brackets that appear outside the example blocks. Check that each example includes its complete closing syntax and that copying the block includes it; done means the affected examples copy as complete code.
