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%
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?
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.
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.
-- UPDATE --
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).
