自定义html标签的默认CSS? [英] Default css for custom html tags?

问题描述

我有时会使用自定义html标记作为其他元素的容器:

I sometimes use custom html tags as containers for other elements:

<message-panel></message-panel>

像上面这样的未知元素是否具有默认样式集，这些样式在主要浏览器中是常见的?

Does an unknown element like the above have a default set of styles, common among the major browsers?

而且，是否可以为页面上的所有未知元素设置默认样式?

And, is it possible to set a default style for all unknown elements on a page?

推荐答案

所有未知元素的计算显示值均为内联"

All unknown elements have a computed display value of "inline" source

您可以使用

* { ... }

对于所有元素，但这意味着您也将覆盖默认元素的所有非特定设置.

for all elements, however this means that you overwrite anything non-specific set for default elements too.

最好继续使用HTML5定义的标记，除非您正在按照Web组件的方式进行操作.

It's better to keep to using HTML5 defined tags unless you're doing something along the lines of webcomponents.
