In this context, *safe* means CSS content that matches any of the following:

1. The CSS3 stylesheet production, such as `p { color: purple }`.
2. The CSS3 rule production, such as `a[href=~"https:"].foo#bar`.
3. CSS3 declaration productions, such as `color: red; margin: 2px`.
4. The CSS3 value production, such as `rgba(0, 0, 255, 127)`.

Example: Given `style = "color: red;"` defined in the front matter of your `.md` file:

* `<p style="{{ .Params.style | safeCSS }}">…</p>` &rarr; `<p style="color: red;">…</p>`
* `<p style="{{ .Params.style }}">…</p>` &rarr; `<p style="ZgotmplZ">…</p>`

{{% note %}}
`ZgotmplZ` is a special value that indicates that unsafe content reached a CSS or URL context.
