1 06.结合@apply实现样式抽离

前面已经完成了 login 页面的开发，但是代码看起来有点臃肿，这里我们使用 @apply 实现样式抽离

<template>
    <el-row class="login-container">

        <!-- 登录页左边 -->
        <el-col :lg="16" :md="12" class="left">
            <div>
                <div>欢迎光临</div>
                <div>这是描述信息</div>
            </div>
        </el-col>

        <!-- 登录页右边 -->
        <el-col :lg="8" :md="12"  class="right">
            <h2 class="title">欢迎回来</h2>
            <div>
                <span class="line"></span>
                <span>账号密码登录</span>
                <span class="line"></span>
            </div>


            <el-form :model="form" class="w-[250px]">
                <el-form-item>
                    <el-input v-model="form.username" placeholder="请输入用户名">
                        <template #prefix>
                            <el-icon><User /></el-icon>
                        </template>
                    </el-input>
                </el-form-item>
                <el-form-item>
                    <el-input type="password" v-model="form.password" placeholder="请输入用户密码" show-password>
                        <template #prefix>
                            <el-icon><Lock /></el-icon>
                        </template>
                    </el-input>
                </el-form-item>
                <el-form-item>
                    <el-button round color="#626aef" class="w-[250px] round" type="primary" @click="onSubmit">登录</el-button>
                </el-form-item>
            </el-form>
        </el-col>
    </el-row>
</template>



<script setup>
import { reactive } from 'vue'

// do not use same name with ref
const form = reactive({
  username: '',
  password: '',

})

const onSubmit = () => {
  console.log('submit!')
}
</script>


<style scoped>
.login-container {
    @apply min-h-screen;
}

.login-container .left, .login-container .right {
    @apply flex justify-center items-center;
}

.login-container .left {
    @apply bg-indigo-500;
}

.login-container .right {
    @apply bg-light-500  flex-col ;
}


.left>div>div:first-child {
    @apply text-3xl font-bold text-light-50 mb-8;
}

.left>div>div:last-child {
    @apply text-gray-50 text-sm;
}


.right .title {
    @apply font-bold text-gray-800 text-3xl;
}

.right>div {
    @apply flex items-center justify-center my-5 text-gray-300 space-x-2;
}

.right .line {
    @apply h-1 w-16 bg-gray-200;
}

</style>
