側導航摺疊按鈕

側導航沒有對齊，我一直在關注該框架的文檔。在這裏看到圖片。側導航摺疊按鈕

而預期結果是這樣的：

能否請你幫我爲什麼不對齊？

<!--Import jQuery before materialize.js-->

<script type="text/javascript"> 

    $(document).ready(function(){ 
// Initialize collapse button 
$(".button-collapse").sideNav(); 
// Initialize collapsible (uncomment the line below if you use the dropdown variation) 
$('.collapsible').collapsible(); 



}); 


</script> 
</body> 
</html>

CTRL˚F POI 1 - 下面是其中可摺疊應該對齊 POI 2 - 應該是被激活最小化sidenav瀏覽器被最小化時的一個 POI 3 - 側導航的內容

你能幫忙嗎？我已經看過了materialize的代碼，我只是將它實現在我的代碼中，但我不知道它爲什麼不對齊。
