In this chapter, we have had a good look at some of Sass's most complex, yet powerful capabilities. We have learned how to use control directives to create limitless loops of styles. We have also learned about interpolation and how it can be used to generate the values of variables anywhere we need them. We've also looked at functions and how we can use Sass's mathematical capabilities and operators to create logic in our style sheets.

It's fair to say we've come a long way. Despite this, the examples we have covered are fairly pedestrian. It's now up to you to take these basic concepts and bend things to your will. I know you'll do us both proud.

In our final chapter, we're going to look at some of the finer techniques we can employ with Sass and Compass and do a final code review of the styles we've written thus far. We will also consider how to switch off support for different browser vendors, use the Sass interactive shell, clear the Sass cache and a whole lot more.
