# CSS Custom Properties

This template is dedicated for Web developers using CSS. It helps you generate all types of design tokens as CSS Custom Properties in their respective CSS file.

This example uses four different parsers:

* [filter](https://docs.specifyapp.com/sdtf-beta/parsers/filter) to target on a specific collection named "Colors" that contains our colors
* [convert-color](https://docs.specifyapp.com/sdtf-beta/parsers/convert-color) to convert our colors in HSL
* [change-case](/v1/advanced-repository/parsers/change-case.md) to change the name of our tokens and modes to kebabCase
* [to-css-custom-properties](https://docs.specifyapp.com/sdtf-beta/parsers/to-css-custom-properties) to generate a CSS file containing our tokens

This template is an example among others. Head toward the [to-css-custom-properties](https://docs.specifyapp.com/sdtf-beta/parsers/to-css-custom-properties) page to get all available options. 

## CLI configuration

When using the CLI, you need to fill three properties:

* `repository`  is `@organization/repository`
* `personalAccessToken` which you can generate [in your account settings](https://specifyapp.com/user/personal-access-tokens) 
* `rules` lets you transform tokens by chaining parsers

```json
{
  "version": "2",
  "repository": "@organization/repository",
  "personalAccessToken": "<your-personal-access-token>",
  "rules": [
    {
      "name": "css",
      "parsers": [
        {
          "name": "filter",
          "options": {
            "query": {
              "where": {
                "collection": "Colors",
                "select": {
                  "parents": true,
                  "children": true
                }
              }
            }
          }
        },
        {
          "name": "convert-color",
          "options": {
            "toFormat": "hsl",
            "applyTo": {
              "collection": true
            }
          }
        },
        {
          "name": "change-case",
          "options": {
            "change": "names",
            "toCase": "kebabCase",
            "applyTo": {
              "collection": true
            }
          }
        },
        {
          "name": "change-case",
          "options": {
            "change": "modes",
            "toCase": "kebabCase",
            "applyTo": {
              "collection": true
            }
          }
        },
        {
          "name": "to-css-custom-properties",
          "output": {
            "type": "file",
            "filePath": "tokens.css"
          }
        }
      ]
    }
  ]
}
```

## GitHub configuration

If you use the GitHub, you need to fill two properties:

* `repository`  is `@organization/repository`
* `rules` lets you transform tokens by chaining parsers

{% hint style="info" %}
Make sure you have connected your GitHub account with your Specify account. Head toward [this article](https://help.specifyapp.com/en/articles/4722440-add-github-as-a-destination) to learn more.
