样式代码小总结

1.弹窗居中显示，内容过高自行滚动。

 .dialog /deep/.el-dialog { display: flex; flex-direction: column; margin: 0 !important; position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); max-height: calc(100% - 200px); max-width: calc(100% - 100px); .el-dialog__body { flex: 1; overflow: auto; }
 }

1.去除el-table上selection column上最顶端的checkbox框，让table 无法进行全选

/deep/.el-table {th {.cell {&::before {content: "";position: absolute;}.el-checkbox__inner {display: none;position: relative;}}}
}

遇到问题1

vue-cli3安装scss时，一直报错： Syntax Error: TypeError: this.getOptions is not a function

查了一下发现,是因为安装的sass-loader版本太高了。。。

# 卸载
 npm uninstall sass-loader
# 重装指定版本
 npm install sass-loader@7.0.1 --save-dev

卸载后，重新安装即可解决问题。

开始编写简易的全局样式scss文件

文件夹路径：

|---src
|----assets
|-----scss
|------elementStyle //各个组件样式的重写
|-------button.scss
|-------checkbox.scss
|-------index.scss
|-------input.scss
|-------inputNumber.scss
|-------radio.scss
|------style.scss //样式输出文件
|------varible.scss //定义的变量和公共mixin

当然这个可以根据自己的喜好自行调整

varible.scss:
