In AngularJS Material's official site, I tried this demo on my laptop: AngularJS Material | Custom Separator Keys. Everything's good except for my <code> HTML element tag that doesn't get the right CSS styling. I inspected the element and this should be the actual style (like the result in AngularJS Material Demo and also in codepen):
I don't know what is wrong with my code. Having the problem in my <code> element tag could mean that it might be the same case if I use the other HTML elements in my code (not getting the AngularJS Material Design).
PS. My code is different from the demo because I have to change the format of my code in order for it to work (I don't know the reason why I can't directly inject "the self-invoking function-way" to my controller. I had to create a module first before I can connect it with my controller)
Here is my code:

Thank you!

<code>styling in the documention is coming from a seperate stylesheet and isn't part of the AngularJS Material standard CSS.
