有没有人使用react.js和Material UI库构建网页?我应该如何调整图标大小?它是一个 svg 图标。我刚刚构建了一个“创建新”组件,它是一张材料纸,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;
它看起来不错(确保您以全尺寸查看),但图标太小。然后我打开chrome dev工具,看到如下html代码。

使用 chrome dev 工具,我修改了 svg 图标大小和 svg 的 viewbox 属性,并使浏览器中的图标更大。但我不确定如何在我的代码中调整图标大小。如果我写一个 CSS 文件来修改 svg,如果有多个 svg 元素就会有问题。
