我正在使用 AngularJS 和 Material Design，而困扰我的一件事是我无法准确复制谷歌官方网站上用于按钮标签的样式。 材料设计按钮演示
当我使用这样的按钮时：
<md-button class="md-raised md-primary">Start</md-button>
<md-button class="md-raised md-primary"><label>Start</label></md-button>
我得到这样的东西：
我期待有这样的东西：
这有点像我根据他们网站上提供的源代码编写的代码
<md-button class="md-raised md-primary">Primary</md-button>
我尝试使用<b></b>标签而不是标签，但结果相似，有些字母不太合适......我是否缺少一些东西来解决这个字体问题？
编辑：我的代码之一的示例。
(function() {
angular
.module("demoApp", [
"ngMaterial",
"app.config",
"app.controller"
]);
})();.md-button {
min-width: 10em;
