A CodePen by Captain Anonymous. Sass flat-design-button mixin - Playing w/ flat design and fancy Sass functions. See the code for details.
**UPDATE:** I wrote some explaining comments.

##Main Ideas
1. Write a mixin that makes awesome flat buttons w/ icons in variable positions.

2. Store the Unicode-entities for the icons in one place and make them referenceable by a name that is easy to remember.

3. Automagically set the the text color of the buttons based on the background color.


##Interesting Code bits to check out:

- **Line 11-18 -** Defining the icons
- **Line 59-72 -** Color mechanism
- **Line 77-95 -** Handling the Icons
- **Line 131-136 -** Using the mixin
