Exploring the utilization of CSS host selectors with Angular4 to target direct child elements

Within my app.component.css file, I currently have the following code snippet:

* ~ * {
  margin-top: 24px;
}

This rule actually adds some top margin to all elements that come after the first one. However, this is not exactly what I intend to achieve. My goal is to only target the direct children of the host element.

To try and accomplish this, I made the following adjustment :

:host > * ~ :host > * {
  margin-top: 24px;
}

Unfortunately, this modification does not seem to have any effect. What could I be overlooking in this situation?

Answer №1

Utilizing just one :host > suffices — the sibling combinator aligns the two * selectors effortlessly:

:host > * ~ *

This translates to

Pick any element
that comes after a child element
of the host element.

... indicating that the selector's focus is on a child of the same host element as the subsequent element, in line with the definition of "sibling."
