截至2019年2月27日，新的材质图标主题有CSS字体。
但是，您必须创建CSS类来使用字体。
字体系列如下:
材料图标轮廓-轮廓图标
材质图标双色-双色图标
圆形的图标
材质图标锐利-锐利的图标

编辑:截至2019年3月10日，似乎现在有了新的字体图标类:
body {
font-family: Roboto, sans-serif;
}
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500|Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp">
</head>
<body>
<section id="original">
<h2>Baseline</h2>
<i class="material-icons">home</i>
<i class="material-icons">assignment</i>
</section>
<section id="outlined">
<h2>Outlined</h2>
<i class="material-icons-outlined">home</i>
<i class="material-icons-outlined">assignment</i>
</section>
<section id="two-tone">
<h2>Two tone</h2>
<i class="material-icons-two-tone">home</i>
<i class="material-icons-two-tone">assignment</i>
</section>
<section id="rounded">
<h2>Rounded</h2>
<i class="material-icons-round">home</i>
<i class="material-icons-round">assignment</i>
</section>
<section id="sharp">
<h2>Sharp</h2>
<i class="material-icons-sharp">home</i>
<i class="material-icons-sharp">assignment</i>
</section>
</body>
</html>
编辑#2:这是一个通过使用CSS图像过滤器来着色双色图标的变通方法(代码改编自此评论):
body {
font-family: Roboto, sans-serif;
}
.material-icons-two-tone {
filter: invert(0.5) sepia(1) saturate(10) hue-rotate(180deg);
font-size: 48px;
}
.material-icons,
.material-icons-outlined,
.material-icons-round,
.material-icons-sharp {
color: #0099ff;
font-size: 48px;
}
