Code block color changes and removed extra space in minification example. 

This is a great guide.

I noticed while reading the guide that the "..." is being shown as bright red in a couple examples for me. I changed those code blocks to be javascript syntax and surrounded the "..." with a comment to keep from syntax highlighting it as bright red.

In the minification example there is a space in the example output so I removed that too.

I added bash syntax highlighting to the commands, might be overkill but it made it look nicer to me.
