Recently, I created a tutorial about how to avoid ::ng-deep when styling Angular components. Many of you didn’t like the techniques I provided so I thought it would be good to follow up to clear up some misconceptions and provide more specific examples. In short, I think you should try to avoid using it because its use is discouraged by the Angular team. In this example, I’ll explain why and I’ll show you some things that I like to do instead.
Hey everyone, welcome back! In this tutorial, we’re diving into something that’s been a challenge in the past for Angular developers, the need to break style encapsulation in certain cases with ::ng-deep. It’s been deprecated for quite some time but there are still times where we need to use it. Or at least there used to be. Now, we have modern solutions that not only replace ::ng-deep but can also make code cleaner and more maintainable.
Sometimes you may need to programmatically set the value for a CSS custom property while building components in Angular. I occasionally run into situations where I need to use a custom property based on a dynamic value. Like a bar chart for example, where the items in the chart are based on data from an api. Well in this example, we’re going to look at three different ways to set custom properties programmatically. We’ll use basic style binding, then we’ll use the Renederer2 setStyle() method, and after that, we’ll use host element binding.
