我是一名有用的助手，可以协助你翻译文本。
我正在尝试使materializeCSS中的FAB起作用，但我尝试的任何方法都没有奏效。这是我的代码：
index.html:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>DevWright Education</title>
<base href="/">
<meta name="viewport" content="width=device-width, initial-scale=1">

</html>
new-post-card.component.html:
<div class="card">
<div class="card-content">
<span class="card-title">Post something!</span>
<!-- Fixed Action Button -->
<div class="fixed-action-btn horizontal click-to-toggle" style="bottom: 45px; right: 24px;">
<a class="btn-floating btn-large red">
<i class="large material-icons">mode_edit</i>
</a>
<ul>
<li><a class="btn-floating red"><i class="material-icons">insert_chart</i></a></li>
<li><a class="btn-floating yellow darken-1"><i class="material-icons">format_quote</i></a></li>
<li><a class="btn-floating green"><i class="material-icons">publish</i></a></li>
<li><a class="btn-floating blue"><i class="material-icons">attach_file</i></a></li>
</ul>
</div>
</div>
</div>
我尝试使用了angular2-materialize，但我找不到合适的组件与之配合使用。
