Question

What are some ways to change the appearance of a component using its parent?

In order to make changes to the CSS properties of a Vue component from its parent, effectively overriding any existing styles within the component, I am seeking a solution.

Initially, I assumed that styling a component like <my-component> directly from the parent would be straightforward:

my-component {
    font-weight: bolder;
}

However, this approach did not yield the desired results.

As an alternative, I attempted passing a prop to the component containing the necessary information for styling. While this method worked, I am in search of a more elegant solution resembling an inheritance mechanism, where the parent's settings take precedence over those of the child, similar to the styling of a <b> element.

Is there a way to achieve such a mechanism?

When Vue renders the template of a component, custom component tags get replaced with their template definitions. Instead of trying to select the custom component's tag in CSS, it's important to understand that the tag is not actually in the DOM.

To style the custom component using CSS, simply add a class attribute to the root element of the child component. This class will be what gets inserted into the DOM in place of the custom component tag. It's recommended to use the same name for the class as the component itself for easier identification. Then, you can easily select and style the component anywhere in your CSS using .my-component.

For better clarity, here's an example:

Vue.component('my-component', {
  template: `<div class="my-component">Foo</div>`,
})

new Vue({ el: '#app' })

.my-component { color: goldenrod; }

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.3/vue.min.js"></script>
<div id="app">
  <my-component/>
</div>
