饿了么element UI<el-dialog>弹出层</el-dialog>修改默认样式不能在<style scoped>修改

如果在非scoped下，修改el-dialog自动添加的DIV类名的style加上important，可以覆盖原来的width，但这样会让整个项目的样式都乱套。

如果在scoped下修改style。所有的自定义样式都无法覆盖element的样式啊，加上important也不行，

<style scoped>

</style>

<el-dialog :title="titleStr" v-model="dialogFormVisible" custom-class = "dialog">
<el-dialog :title="titleStr" v-model="dialogFormVisible" class = "dialog">

重新命名class名，

定义CSS样式

	<el-dialog title="新增孩子" v-model="addFormVisible" :close-on-click-modal="false">
			<el-form :model="addForm" label-width="85px" :rules="addFormRules" ref="addForm">
				<el-form-item label="姓名：" prop="ChildName">
					<el-input v-model="addForm.ChildName" auto-complete="off"></el-input>
				</el-form-item>
				<el-form-item label="性别：" prop="Gender">
					<el-radio-group v-model="addForm.Gender">
						<el-radio class="radio" label="1">男</el-radio>
						<el-radio class="radio" label="2">女</el-radio>
					</el-radio-group>
				</el-form-item>
				<el-form-item label="生日：" prop="Birthday">
					<el-date-picker type="date" placeholder="选择日期" v-model="addForm.Birthday"></el-date-picker>
				</el-form-item>

			</el-form>
			<div slot="footer" class="dialog-footer">
				<el-button @click.native="addFormVisible = false">取 消</el-button>
				<el-button type="primary" @click.native="addSubmit" :loading="addLoading">提 交</el-button>
			</div>
		</el-dialog>
