Ignis is a Sass library that I developed to create websites. Its main feature is a BEM system, though it also includes some other useful features:

Easing background gradients
Context stacks: A temporary data storage
Property trees: A persistent data storage
Responsive properties: A generalization of responsive typography
Modular scales

One of the quickest wins—and one of the first things I recommend my clients do—to make websites faster can at first seem counter-intuitive: you should self-host all of your static assets, forgoing others’ CDNs/infrastructure. In this short and hopefully very straightforward post, I want to outline the disadvantages of hosting your static assets ‘off-site’, and the overwhelming benefits of hosting them on your own origin.
