### Deprecated
The [itcss](https://www.freecodecamp.org/news/managing-large-s-css-projects-using-the-inverted-triangle-architecture-3c03e4b1e6df/) folder is deprecated. The infrastructure here is from a former era of the extension. The files and some sporadic styling are still used in the codebase but should not be extended. The MetaMask team will gradually move the valid styles from this folder into the [css](/css) folder. Eventually the itcss folder will be removed.
