function-url-scheme-disallowed-list

指定不允许的 URL 方案的列表。

¥Specify a list of disallowed URL schemes.

a { background-image: url('http://www.example.com/file.jpg'); }
/**                        ↑

 *           This URL scheme */

网址方案 由字母数字、+、- 和 . 字符组成。它可以出现在 URL 的开头，后跟 :。

¥A URL scheme consists of alphanumeric, +, -, and . characters. It can appear at the start of a URL and is followed by :.

该规则忽略了：

¥This rule ignores:

  • 没有现有 URL 方案的 URL 参数

    ¥URL arguments without an existing URL scheme

  • 带有变量或变量插值的 URL 参数（$sass、@less、--custom-property、#{$var}、@{var}、$(var)）

    ¥URL arguments with variables or variable interpolation ($sass, @less, --custom-property, #{$var}, @{var}, $(var))
