Utilizing consistent CSS styles across VueJS components

Question

Utilizing consistent CSS styles across VueJS components

Currently tackling a VueJS 2 project and facing issues with scoped styling when cleaning up the code.

My setup involves 3 components that share similarities, prompting me to utilize mixins for consolidating the code into one file. Each component makes use of these mixins for both template and vuejs functionalities. If I need to tweak specific conditions for a particular component, I can easily override the code within it, which is functioning smoothly so far.

However, my aim now is to transfer the scoped style to the mixins as well. Currently, the style is enclosed in

<style lang="scss" scoped></style>

tag, working effectively within its respective component but necessitating duplication of styling codes across all 3 components.

I could opt to include these styles in the global CSS file, but restricting them to only one of the 3 components poses a challenge.

Is there a method to incorporate these styles and apply them to mixins?

What approach would be considered best practice for addressing this scenario?

Answer №1

Vue simplifies this process.

Resolution

To incorporate shared styles in a component, follow these steps:

MyComponent.js

<template>
</template>

<script>
</script>

<style lang="scss" scoped>
  @import '@/scss/shared-styles.scss';
  @import 'styles.scss'; // regular CSS for the component
</style>

Another Approach

You may also import the shared CSS files directly within the component's CSS file as shown below.

MyComponent.js

<template>
</template>

<script>
</script>

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

styles.scss

@import '@/scss/shared-styles.scss'

// remaining component-specific CSS

Automatically Include Global Styles

If you want certain styles to be accessible in ALL your components, consider this method.

vue.config.js

module.exports = {
  ...
  css: {
    loaderOptions: {
      sass: {
        prependData: `
          @import "@/scss/global.scss";
        `
      },
    },
  },
}

Answer №2

I recently discovered that the scoped style also impacts child components.

As a result, I came up with a solution that may not be considered best practice, but it works well for me.

To implement this, I created a WrapperComponent where I placed the scoped style along with a simple template.

<template>
    <div>
        <slot></slot>
    </div>
</template>

<style lang="scss" scoped>
    /* CSS styles applied to all children */
</style>

The idea is that by wrapping any components with the WrapperComponent, the HTML content will be passed through the slot without alteration and the styles will automatically apply.

In my use of mixins, I imported the wrapper and wrapped the component template with the WrapperComponent. Here's an example:

import WrapperComponent from './WrapperComponent'

let MyMixins = {

    template: `<wrapper-component>
        <div>
            Insert your HTML code here
        </div>
    </wrapper-component>`,


    components: {
        WrapperComponent,
    },
};

By using this mixins or in a child component, the styles from WrapperComponent will automatically be applied, making it easy to maintain consistency across different groups of components sharing the same parent style.

Consider utilizing modules in place of creating a style section with a scoped attribute.

By doing so, your CSS will remain scoped and separate from your overall styling.

Successfully integrated my fadeTransition.css file into the /assets directory of my vue app, and imported it using this method:

<template>
  <transition name="fade">
    <div v-if="showContent">test</div>
  </transition>
</template>
<script>
  import '@/assets/fadeTransition.css';
  // component definition
</script>

Contents of fadeTransition.css:

/* fade menus in, not out */
.fade-enter-active {
  transition: opacity .5s;
}
.fade-enter {
  opacity: 0;
}

Efficient and straightforward. Also compatible with scss.

Cheers!
