How vue displays styles

Vue is a popular JavaScript framework that allows developers to easily create complex single-page applications. In the Vue development process, display style is a key task.

In Vue development, there are many ways to display styles. The more common methods are:

1. Embedded style sheet (<style> tag): Vue allows in component files Embedded style sheet. This approach is very flexible and allows developers to easily customize the component's appearance.

For example:

<template>
  <div class="my-component">
    <p>Hello, World!</p>
  </div>
</template>

<style>
.my-component {
  font-size: 24px;
  color: blue;
}
</style>

In the above code, we used the <style> tag in the component file and set .my- Font size and color of component class. This way, when using the component, the font size and color will appear as we expect.

2. Introducing external style sheets: Vue also allows developers to introduce external style sheets into component files. This approach can help reduce developer workload and make styles easier to maintain.

For example:

<template>
  <div class="my-component">
    <p>Hello, World!</p>
  </div>
</template>

<style src="./my-style.css"></style>

In the above code, we introduced an external style sheet named my-style.css. In this style sheet, we can define some global styles so that they can be reused in other components.

3. Inline styles: In some cases, developers may need to use inline styles in Vue components. Inline styles can quickly implement some simple styling needs, but their flexibility is relatively low.

For example:

<template>
  <div class="my-component" :style="{ color: textColor }">
    <p>Hello, World!</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      textColor: 'blue'
    }
  }
}
</script>

In the above code, we use Vue’s v-bind:style directive to set the text color of the component. We bind the textColor variable to the color property of the style object, so that when the value of the textColor variable changes, the text color will also change at the same time.

To sum up, Vue’s display style method is very flexible and can meet the various needs of developers. When developing with Vue, you can choose the appropriate method to set the style according to the actual situation.
