如何以及在何处使用 ::ng-deep? [英] How and where to use ::ng-deep?

问题描述

我是 Angular 4 的新手，所以谁能解释一下在 Angular 4 中如何以及在何处使用 ::ng-deep?

其实我想从父组件覆盖子组件的一些CSS属性.另外IE11支持吗?

感谢您的帮助.

解决方案

通常 /deep/shadow-piercing" 组合器可用于强制样式向下子组件.这个选择器有一个别名 >>>现在还有一个叫做 ::ng-deep.

由于/deep/combinator已被弃用，推荐使用::ng-deep

例如:

和css

.overview {::ng-深{p{&:last-child {底边距:0；}}}}

它将应用于子组件

I'm new to Angular 4, so could anyone please explain how and where to use ::ng-deep in Angular 4?

Actually I want to overwrite some of the CSS properties of the child components from the parent components. Moreover is it supported on IE11?

Thanks for the help.

解决方案

Usually /deep/ "shadow-piercing" combinator can be used to force a style down to child components. This selector had an alias >>> and now has another one called ::ng-deep.

since /deep/ combinator has been deprecated, it is recommended to use ::ng-deep

For example:

<div class="overview tab-pane" id="overview" role="tabpanel" [innerHTML]="project?.getContent( 'DETAILS')"></div>

and css

.overview {
    ::ng-deep {
        p {
            &:last-child {
                margin-bottom: 0;
            }
        }
    }
}

it will be applied to child components
