Challenge: Create Reusable CSS with Mixins

Link to the challenge:

There is a nice way you can learn sass. Copy all the html and scss over to, once you set that up, click on the :gear: icon and select view compiled css.

The :gear: can be found right besides the CSS name for the section.

For this first time, I set it up for you.

As for a conceptual explanation. mixins are pieces of code you define and call anywhere you want, somethine like this:

@mixin mymix(args){}

@include mymix(args)

@include mymix (args)

Where args are optional.
