Please clean up your sass code by

• [x] removing browser prefixes and
• [x] alphabetizing property sort order

Depending on your text editor, you should be able to do this automatically or with some kind of shortcut.

With Sublime Text Editor, for example, you can highlight a set of properties and hit F5 to automatically sort them in alphabetical order.

@hyakurendev I assume that we would not take care of browser compatibility in this case when we remove browser prefixes.

@vitusignacio Yes, please assume we are using an autoprefixer
