safecss	safeCSS	Declares the provided string as a known "safe" CSS string.	https://golang.org/src/html/template/content.go?s=919:929#L15	2017-02-01	2017-02-01	2017-02-26	functions	style css strings					safeHTML safeHTMLAttr	false

safeCSS declares the provided string as a known "safe" CSS string so that Go html/templates will not filter it as unsafe.

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> → <p style="color: red;">…</p>
• <p style="{{ .Params.style }}">…</p> → <p style="ZgotmplZ">…</p>

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