All class names and IDs in CSS are global, which makes it extremely difficult to maintain in large-scale projects. No matter how well you specify your naming conventions, vanilla CSS is a pretty messy language to work with.

Both of them are allowing us to separate the style sheets into logical modules (files), create variables, mix in classes, and generate CSS with loops and conditions. At the end of the development cycle, we can compile all the files into one or many plain CSS files before moving the styles to production.
Let's set up a simple Meteor app and implement the same grid with LESS.
In the terminal, run the following command:
>> meteor create less_app;
We need to add the less package, as follows, to allow Meteor to compile...
