是否有人使用react.js和Material
UI库构建网页？我应该如何调整图标大小？这是一个svg图标。我刚刚构建了一个“创建新”组件，它是一张纸质材料，顶部有一个内容添加按钮。这是代码。

import React from 'react';

import Paper from 'material-ui/lib/paper';

import ContentAdd from 'material-ui/lib/svg-icons/content/add';

import IconButton from 'material-ui/lib/icon-button';





const styleForPaper = {

  width: '96vw',

  height: '20vh',

  margin: 20,

  textAlign: 'center',

  display: 'inline-block',

};



const styleForButton = {

  'marginTop': '7vh',

};





const PaperToAddNewWidgets = () => (

  <div>



    <Paper style={styleForPaper} zDepth={2}>



    <IconButton

        style={styleForButton}

        touch={true}

        tooltip="Add New Widget">



    <ContentAdd/>



    </IconButton>



    </Paper>

  </div>

);



export default PaperToAddNewWidgets;

看起来不错（确保您正在查看完整尺寸的图片），但是图标太小。然后，我打开了chrome dev工具，并看到了以下html代码。

使用chrome
dev工具，我修改了svg图标的大小和svg的viewbox属性，并在浏览器中将其放大。但是我不确定如何在代码中调整图标大小。如果我写了一个CSS文件来修改svg，那么如果有多个svg元素，那将是一个问题。
