你能在布局中使用Jekyll页面变量吗？

I'm using Jekyll for my blog, and I'd like the ability to use unique CSS styling in particular posts. Right now, I'm specifying a CSS file in the YAML frontmatter like so:

我正在使用Jekyll作为我的博客,我希望能够在特定帖子中使用独特的CSS样式。现在,我正在YAML前端中指定一个CSS文件,如下所示:

style: artdirection.css

and using it in the layout like this:

并在布局中使用它像这样:

{% if page.style %}
    <link rel="stylesheet" href="{{ page.style }}">
{% endif %}`

This works, but I'd prefer to include the actual CSS styling in a style tag in the page's frontmatter instead of linking to a style sheet.

这有效,但我更喜欢在页面的frontmatter中的样式标记中包含实际的CSS样式,而不是链接到样式表。

I've tried dealing with this in a couple of ways, including the method described here, but the variable that I capture is only usable inside the post itself, not in the layout.

我试过用两种方法处理这个问题,包括这里描述的方法,但是我捕获的变量只能在帖子本身内部使用,而不能在布局中使用。

So, is it possible?

那么,有可能吗?

2 个解决方案

#1

I'm pretty sure this would work:

我很确定这会起作用:

---
title: xxx
style: |
  /* You can put any CSS here */
  /* Just indent it with two spaces */
  /* And don't forget the | after "style: " */
  h2 {
    color: red;
  }
---

Your markdown/textile goes here. h2s will be red

And then in your layout:

然后在你的布局中:

<style type="text/css">
{{ page.style }}
</style>

And that should be it.

这应该是它。

Now variables declared in the layout front-matter (_layouts/default.html) are visible via:

现在,通过以下方式可以看到在布局前端(_layouts / default.html)中声明的变量:

{{ layout.style }}

instead of the older:

而不是旧的:

{{ page.style }}
