Jekyll：在SCSS中使用_config.yml中的值

Question

在我的Jekyll项目中，我在_config.yml文件中有以下内容：

colors:
  - name: red
    hex: '#FF0000'
  - name: yellow
    hex: '#FFFF00'
  - name: blue
    hex: '#0000FF'

在assets/css/colors.scss中，我想为颜色创建类，如下所示：

{% for color in site.colors %}
.{{ color.name }} {
  color: {{ color.hex }};
}
{% endfor %}

当我这样做时，我收到以下错误：

Error in _assets/css/background-test.scss:6 Invalid CSS after "}": expected selector or at-rule, was "{% for color in..." 
  Liquid Exception: Invalid CSS after "}": expected selector or at-rule, was "{% for color in..." in _includes/head.html, included in _layouts/default.html
jekyll 3.0.1 | Error:  Invalid CSS after "}": expected selector or at-rule, was "{% for color in..."

有没有办法让Liquid处理SCSS中_config.yml文件的值？

Answer 1

如果您希望Jekyll处理您的scss文件，您必须为其添加前端内容。

这有效：

---
# empty front matter
---
@charset "utf-8";

{% for color in site.colors %}
.{{ color.name }} {
  color: {{ color.hex }};
}
{% endfor %}
