Angular 2：如何设计组件的主机元素？ [英] Angular 2: How to style host element of the component?

问题描述

我在Angular 2中的组件称为my-comp：

I have component in Angular 2 called my-comp:

<my-comp></my-comp>

在Angular 2中如何设计此组件的主机元素？

How does one style the host element of this component in Angular 2?

在Polymer中，您将使用：host选择器。我尝试它在Angular 2.但它不工作。

In Polymer, You would use ":host" selector. I tried it in Angular 2. But it doesn't work.

:host {
  display: block;
  width: 100%;
  height: 100%;
}

我也尝试使用组件作为选择器：

I also tried using the component as selector:

my-comp {
  display: block;
  width: 100%;
  height: 100%;
}

这两种方法似乎都无效。

Both approaches don't seem to work.

感谢。

推荐答案

有一个错误，但是在此期间已修复。 ：host {} 现在可以正常工作。

There was a bug, but it was fixed in the meantime. :host { } works fine now.

还支持

• ：host（selector）{...} for selector 匹配属性，类...在主机元素上



• ：host-context（selector）{...} selector 匹配父组件上的元素，类...

• :host(selector) { ... } for selector to match attributes, classes, ... on the host element

• :host-context(selector) { ... } for selector to match elements, classes, ...on parent components
