| > **Note:** We are in the process of deprecating the `mdn/data` package in favor of [`w3c/webref`](https://github.com/w3c/webref). If this could present a problem to your project, please contact us via our [GitHub discussions](https://github.com/mdn/mdn-community/discussions/categories/platform). Thank you. |

| Maintained by the [MDN team at Mozilla](https://wiki.mozilla.org/MDN). |
| |
| This repository contains general data for Web technologies. |
| |
| This data is used in MDN documentation, to build |
| [information boxes](https://developer.mozilla.org/en-US/docs/Web/CSS/background) |
| or [sidebar navigation](https://developer.mozilla.org/en-US/docs/Web/API/Window). |
| External tools have started to make use of this data as well. |
| For example, the [CSSTree](https://github.com/csstree/csstree/) CSS parser. |
