safe.CSS

safe.CSS

Declares the given string as a safe CSS string.

Introduction #

Usage #

Use the safe.CSS function to encapsulate known safe content that matches any of:

  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).

Use of this type presents a security risk: the encapsulated content should come from a trusted source, as it will be included verbatim in the template output.

See the [Go documentation] for details.

Example #

Without a safe declaration:

{{ $style := "color: red;" }}
<p style="{{ $style }}">foo</p>

Hugo renders the above to:

<p style="ZgotmplZ">foo</p>

To declare the string as safe:

{{ $style := "color: red;" }}
<p style="{{ $style | safeCSS }}">foo</p>

Hugo renders the above to:

<p style="color: red;">foo</p>
