How to Utilize Custom Component Tag Names in CSS with Vue.js 2?

<template>
    <header>
        <hamburger></hamburger>
        <app-title></app-title>
        <lives></lives>
    </header>
</template>

<script>
export default {
    name: 'Titlebar',
    data() {
        return {

        }
    }
}
</script>

<style lang="scss" scoped>
    @import "../styles/variables";

    header {
        padding: $padding-titlebar;
        position: relative;
    }
    lives {
        position: absolute;
        right: 2.5vh;
    }
</style>

Is it feasible to utilize component tags as regular HTML tags for styling purposes, such as shown in the lives { } section?
I have observed that using <lives class="lives"> and applying .lives { } in CSS can achieve the desired effect, but this approach seems somewhat redundant. I would prefer to avoid adding additional classes if possible and simply use the component tag itself.
I realize that Vue compiles <lives> into HTML code and that there is no corresponding "lives" tag for CSS to reference post-compilation, but the thought still intrigues me.

Answer №1

The naming of a Vue component is not related to CSS rules, but its template is.

A Vue component contains a template property which includes HTML tags. You can also use custom HTML tags within the template. For example:

template: `<lives class="lives">{{a}}</lives>`

Now you can apply CSS rules to the lives tag.

Answer №2

For those seeking to integrate Vue elements into their projects, consider using vue-custom-element:

https://github.com/karol-f/vue-custom-element

To begin, register your component by following these steps:

Vue.customElement('widget-vue', {
  props: [
    'prop1',
    'prop2',
    'prop3'
  ],
  data: {
    message: 'Hello Vue!'
  },
  template: '<p>{{ message }}, {{ prop1  }}, {{prop2}}, {{prop3}}</p>'
});

After registering the element, you can customize its appearance with CSS properties:

widget-vue {
  display: block;
  background: red;
  ...
}

If you wish to register a Single File Component, simply import it and include it in the registration process:

import TopBar from '@/components/core/TopBar'
Vue.customElement('top-bar', TopBar)

We hope this information proves helpful in your development endeavors. Best of luck!
