用什么代替:: ng-deep [英] What to use in place of ::ng-deep
问题描述
我正在尝试将路由器插座放置的元素设置为有角度的样式，并希望确保生成的元素的宽度为100％
I'm trying to style an element placed by the router outlet in angular and want to make sure that the element generated gets a width of 100%
从大多数答复中，我看到我应该使用::ng-deep选择器，但是从Angular的
From most of the replies, I'm seeing that I should use the ::ng-deep selector, but from Angular's docs it is being deprecated. Is there an alternative to ::ng-deep?
推荐答案
FWIW在我的研究中，我没有发现ng-deep的任何替代品或其他适用的替代品.我相信这是因为，Angular团队正在遵循影子dom的W3C规范，该规范最初具有诸如deep之类的选择器.但是，W3c自此删除了该建议，但未用新建议取代它.在此之前，我想像Angular团队将保留::ng-deep及其可用的替代方案，但由于W3C草案的待定状态而处于弃用状态.我现在无法花时间来找到支持该文档的文档，但是最近才看到它.
FWIW In my research I have not found any replacement for ng-deep or the other applicable alternatives. This is because, I believe, the Angular team is deferring to the W3C spec on the shadow dom, which initially had selectors such as deep. However, the W3c has since removed the recommendation, but not replaced it with a new one. Until that happens, I imagine that the Angular team will keep ::ng-deep and it's alternatives available, but in deprecated state due to the pending state of W3C's drafts. I am not able to take the time to find the documentation to back this up right now but I did see it recently.
长话短说:继续使用::ng-deep及其替代方法，直到创建替代项为止-弃用只是一个早期通知，因此，只要实际的更改实现，人们就不会盲目.
Long story short: Keep using ::ng-deep and its alternatives until a replacement is created - the deprecation is just an early notice so that people aren't blindsided whenever the actual change materializes.

https://drafts.csswg.org/css-scoping-1/ 如果您有兴趣，这是建议草案.看来他们正在为影子dom树中的元素选择器的强大集合.我认为正是该规范一旦获得批准，便会通知角度克隆(如果有的话)(即，一旦在浏览器中启用，角度可能不需要实现自己的选择器).
https://drafts.csswg.org/css-scoping-1/ Here is the draft proposal if you're interested. It appears that they are working on a robust set of selectors for elements within a shadow dom tree; it is this spec, once approved, that I think will inform the angular clone, if there even is one (i.e. angular may not need to implement their own selectors once this goes live in browsers).
