更改“材质设计”图标的图标大小
问题描述：
我已引用然后声明了一个图标
I have referenced then declared an icon
<i class="material-icons">face</i>
但我该如何更改图标大小？
But how can I change the icon size?
在官方网站 https://design.google.com/icons/ 我可以看到他们使用 class =md-icon dp48但它在我的情况下不起作用。
On oficial site https://design.google.com/icons/ I can see they using classes like class="md-icon dp48" but it is not working in my case.

通过阅读github中的材料设计，我发现这些有用的东西可能对你有帮助。
By reading the material design in github I found these useful stuff that might help you.
/* Rules for sizing the icon. */
.material-icons.md-18 { font-size: 18px; }
.material-icons.md-24 { font-size: 24px; }
.material-icons.md-36 { font-size: 36px; }
.material-icons.md-48 { font-size: 48px; }
/* Rules for using icons as black on a light background. */
.material-icons.md-dark { color: rgba(0, 0, 0, 0.54); }
.material-icons.md-dark.md-inactive { color: rgba(0, 0, 0, 0.26); }
/* Rules for using icons as white on a dark background. */
.material-icons.md-light { color: rgba(255, 255, 255, 1); }
.material-icons.md-light.md-inactive { color: rgba(255, 255, 255, 0.3); }
从上面的代码中，您只需更改或覆盖材料css图标。
From the code above, there you can simply change or override the material css icons.
示例代码：
<i class="material-icons md-18">face</i>
