Phew! We're almost there. We've certainly covered a lot in this chapter! Before we finish the chapter with some tips on avoiding code bloat, we should take a moment to consider one useful function that we've used, but not explored in any detail—this is the use of importing to manage our Less style sheets.

Importing in Less is a simple but useful trick to learn, particularly when managing large style sheets. We can begin to build up a library of code and then import it straight into any future project.

It makes it much easier to manage smaller files, as we can build a master file that imports each of the subfiles into one master; Less will only compile these styles that are directly referenced from our main code. So for example, if your code library file is more than 2,500 lines long, but a mixin of only 10 lines is all that is used, then Less will only include those 10 lines in the final compiled results.

Using the import option is really easy; all you need...
