The `preview.css` is used to help create previews for the Syllabus and Course materials.
In VS Code, update `settings.json` file to include the following:
```
...
"markdown.styles": [
"https://dashboard.thinkful.com/static/build/main.css?8be7f2d85a",
"https://rawgit.com/cklanac/b1a84f86469d9824c29489fecac412b3/raw/6431d942954c5bd0ad9b4b265c131108f65e0b27/preview.css"
],
...
```
`"https://dashboard.thinkful.com/static/build/main.css?8be7f2d85a"` - is the main css for the syllabus
`"https://rawgit.com/cklanac/b1a84f86469d9824c29489fecac412b3/raw/6431d942954c5bd0ad9b4b265c131108f65e0b27/preview.css"` -
This is the raw version of the preview css which is run thru [RawGit](https://rawgit.com/) which adds the proper content-type headers
