How to use Vue and Element-UI to implement mobile responsive design

With the popularity of mobile devices, mobile responsive design is becoming more and more important. Vue and Element-UI are two very popular front-end development tools that can help us quickly implement mobile responsive design. This article will lead you to learn how to use Vue and Element-UI to develop mobile responsive design, and provide code examples.

1. Build the project environment
Before we start, we need to build a project using Vue and Element-UI. You can use Vue's scaffolding tool Vue-CLI to create a basic project.

1. Install Vue-CLI
   Open the command line tool and execute the following command to install Vue-CLI globally:

npm install -g @vue/cli

2. Create project
   The command to create a project using Vue-CLI is as follows:

vue create responsive-design-project

Select the required configuration according to the prompts , and then wait for the project to be created.

3. Install Element-UI
   Enter the project directory and execute the following command to install Element-UI:

npm install element-ui --save

2. Import the Element-UI component
In the project entry file main.js, import and register the Element-UI component. Open the main.js file and add the following code:

import Vue from 'vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index. css'

Vue.use(ElementUI)

In this way, we successfully imported the Element-UI component and registered it in the Vue instance.

3. Use Element-UI components to implement mobile responsive design
Next, let us use Element-UI components to implement mobile responsive design. Element-UI provides a series of components suitable for mobile development.

1. Responsive layout
   Element-UI provides two components, Col (column) and Row (row), which can help us implement responsive layout. In mobile development, we usually need to divide the page into 12 grids, and we can use the Col (column) component to achieve this grid division.

Code example:

In the above code, we use Row (row) and Col (column) components. By setting the span property of the Col component to control the width of each grid, you can achieve responsive layout.

2. Responsive elements
   In addition to responsive layout, sometimes we also need to display different elements according to different screen sizes. Element-UI provides some directives and class names to achieve this.

Code example:

In the above code, we use Vue’s instructions v-if and v-else-if to display different elements according to the screen size. Through the $isXS, $isSM and other properties provided by Element-UI, we can obtain the size information of the current screen.

4. Testing and Optimization
During the development process, we can use Vue's development tools for testing and optimization. Vue provides a development tool Vue Devtools, which can help us quickly check component status and debug code in the browser.

1. Install Vue Devtools
   Open the command line tool and execute the following command to install Vue Devtools globally:

npm install -g @vue/devtools

2. Start Vue Devtools
   Execute the following command to start Vue Devtools:

vue-devtools

Then, enable Vue Devtools in the browser extension.

3. Testing and Optimization
   Through Vue Devtools, we can view the status of components and debug code in real time in the browser. Testing and optimization can be carried out according to the actual situation to ensure the effect of responsive design on the mobile terminal.

5. Summary
This article introduces how to use Vue and Element-UI to implement mobile responsive design. By building a project environment, importing Element-UI components, and using responsive layout and responsive elements, we can quickly implement responsive design on the mobile side. At the same time, testing and optimization through Vue Devtools can ensure the responsive design effect of the mobile terminal. I hope this article will be helpful to everyone in mobile responsive design, thank you for reading!
