How to set a single page in vue not to be affected by the overall style

When using the Vue framework for project development, sometimes you will encounter a problem, that is, a certain page needs to be independent from the entire web page and not affected by the overall style. This article will introduce how to set a single page in Vue not to be affected by the overall style.

1. Issues with global styles in Vue

In most cases, the Vue framework we use is built according to the style of the entire website, which means that the CSS styles we use are It is a global style. These global styles affect all components and pages in our application. However, sometimes we need to make a page unaffected by these styles. For example, if we make a loading page, we hope that this page will not be interfered by any styles and only display the loading animation.

2. Solution

Vue provides a good solution, which is to use scoped attributes. The scoped attribute is syntactic sugar in the Vue framework, which can limit styles to the scope of the current component. This is a very useful feature because we don't have to worry about global styles affecting the content in this component.

Specifically, we can add the scoped attribute to the style tag within the component. For example:

<template>
  <div class="loading">
    <p>Loading...</p>
  </div>
</template>

<style scoped>
.loading {
  margin: 0 auto;
  text-align: center;
}
.loading p {
  font-size: 18px;
}
</style>

In the above example, we defined a component called loading and added the scoped attribute to the style tag. The style defined in this way can only take effect within the loading component, and the styles of other components will not be affected.

In addition, if we want to override the global style, we can use !important to strengthen the priority of the current style. For example:

<template>
  <div class="loading">
    <p>Loading...</p>
  </div>
</template>

<style scoped>
.loading {
  margin: 0 auto!important;
  text-align: center!important;
}
.loading p {
  font-size: 18px!important;
}
</style>

In the above example, we use !important to force the current style to have a higher priority than the global style, so that the global style can be overridden.

3. Summary

In the Vue framework, using the scoped attribute can easily prevent our component styles from being interfered by global styles, ensuring the independence of the components. Using !important allows us to override global styles and achieve some special effects. The use of these two methods allows us to control our website style more freely, providing more choices for our project development.
