Investigate CSS Layers

[ttoino]

Investigate the use of CSS layers to overwrite default SIGARRA styles without using !important or worrying about specificity.

Two alternative approaches were discussed. The first involves dynamically importing all SIGARRA stylesheets in a lower layer. This can have some issues as !important interacts with layers in a very weird way. The second approach would be to download all stylesheets a priori and applying some code analysis to remove unneeded styles.
