Git Ignore SASS cache files

.gitignore

# Ignore docs files
styles/.sass-cache
styles/.sass-cache/*


To untrack a single file that has already been added/initialized to your repository, i.e., stop tracking the file but not delete it from your system use: git rm --cached filename

To untrack every file that is now in your .gitignore:

First commit any outstanding code changes, and then, run this command:

```
git rm -r --cached .
```

This removes any changed files from the index(staging area), then just run:

```
git add .
```

Commit it:
```
git commit -m ".gitignore is now working"
```
