GitHub markdown接受哪些内联html样式? [英] Which inline html styles does GitHub markdown accept?

问题描述

此对markdown如何解释HTML元素进行了非常详尽的描述.但是它没有讨论样式.

This gives a pretty thorough description of how HTML elements are interpreted by markdown. But it does not discuss styles.

到目前为止，我唯一可以使用的就是图像宽度.

So far, the only thing I can get to work is image width.

1. 我无法在任何接受/呈现的内容列表中找到
2. 似乎完全忽略了style="....."属性.
3. 我什至找不到老式样式属性的列表(与 the 样式属性style=...相对)

1. I can't find a list anywhere of what is accepted/rendered
2. It appears that the style="....." attribute is completely ignored.
3. I can't even find a list of the old-fashioned style attributes (as opposed to the style attribute style=...)

编辑
将span更改为div，这是因为div在@chris的回答下被@waylan的注释列入白名单标签中.

EDIT
Change span to div due to div being in the whitelisted tags per @waylan's comment under @chris's answer.

Firefox和Chrome似乎不再渲染任何样式属性.

EDIT 2
It appears that firefox and chrome don't render any style attributes any more at all.

推荐答案

在GitHub将Markdown转换为HTML之后 ，

对HTML进行了清理，积极删除了可能损害您和您的亲属的东西，例如script标签，内联样式以及class或id属性.有关完整的信息，请参见消毒过滤器白名单.

The HTML is sanitized, aggressively removing things that could harm you and your kin—such as script tags, inline-styles, and class or id attributes. See the sanitization filter for the full whitelist.

您是对的:style标签未包含在白名单中.它们将被忽略.

You're right: style tags are not included in the whitelist. They are ignored.

允许的属性因标签而异.我建议参考上面的清洁过滤器链接.它会导致一个相当可读的Ruby源文件.

The permitted attributes differ by tag. I recommend referring to the sanitization filter link above. It leads to a fairly readable Ruby source file.
