I'm using AngularJS and Material Design and one thing that is bothering me is that I can't reproduce exactly the style that is used on google's oficial website for the button tags. 
[Material Deisgn Button Demo](https://material.angularjs.org/#/demo/material.components.button)

When I use a button like this:

```
<md-button class="md-raised md-primary">Start</md-button>
<md-button class="md-raised md-primary"><label>Start</label></md-button>

```

I get something like this:

![Button IMG](https://i.stack.imgur.com/vtxoj.png)

and I was expecting to have something like this:

![enter image description here](https://i.stack.imgur.com/G5mFq.png)

which is kinda the same code that I wrote according to the *source code* provided on their website

```
<md-button class="md-raised md-primary">Primary</md-button>

```

I have tried using `<b></b>` tags instead of the label but the result is similar, some letters doesn't fit very well... Is there something I am missing to fix this font issue?

Edit: Example of one of my codes.

```js
(function() {
  angular
    .module("demoApp", [
      "ngMaterial",
      "app.config",
      "app.controller"
    ]);

})();
```

```css
.md-button {
  min-width: 10em;
}
```
