When using require modular development, in the require.config configuration, when defining the import path of the module, some of them need to rely on css , this time you need to pass the require-css plug-in, which can be downloaded from github to the address: https://github.com/guybedford/require-css.

There will be many downloaded through this address, as shown below, we only need the css.js/css.min.js file.

2. Add the following configuration to the require.config configuration:

3. Complete the above two steps After that, you can add dependencies to the shim in the require.config configuration. When loading ELEMENT, you need to load index.css in advance. The writing method is as follows:

shim:{
    "ELEMENT": {
        "deps": ["vue", "css!assets/vue/element-ui/lib/theme-chalk/index.css"]
    }
},

4. The above solves the problem of module dependence on css, but sometimes when you need to introduce a certain css separately, of course, you can drag it directly to the html page to load. But if you don’t want to do this, you can implement it by rewriting require.config at this time. Write the require configuration as a variable, and then initialize it on the page, as shown below:

To implement the writing method in the above picture, you must first prepare a base.js file. In this file, you only need to write document.body.style.visibility = 'visible'; this sentence is enough (you can also write other ones) , and then add a method to the same js configured in requireConfig to add css to the base dependency. The writing method is the red box in the figure below.

Then call the require_css method on the page and pass in the css address, so that the css will be introduced into the page. The writing is as follows:

And you're done.
