这是我的代码
<template>
<div class="STLViewer">
<el-dialog title="3D预览" v-model="newDialogVisible" style="height: 710px" @close="closeModel" @open="open()">
<div id="container" v-if="newDialogVisible" style="width: 96.2%; height: 300px;"></div>
<el-button class="btn" type="primary" @click="closeModel">确认</el-button>
</el-dialog>
</div>
</template>

.btn {

有什么解决办法吗?我希望上面那段空白去掉
检查一下css吧
