我正在此： http://carousel7.bitballoon.com/缺少自定義圖標在引導4轉盤
我已閱讀各種Q版& A和使用我的代碼的開發者視圖。
當用戶點擊「下一個」或「後退」（自定義圖標）時，他應該能夠看到傳送帶中的下一張幻燈片。我從引導創建與引導4暢飲：
http://v4-alpha.getbootstrap.com/components/carousel/#multiple-carousels
我一直在努力，它在「圖標」的文件夾鏈接到「下一個」圖標。我也嘗試過創建一個自定義字體（用於「下一個」和「後退」），但它不起作用。
<div id="carousel-example-generic" class="carousel slide" data- ride="carousel">
<div class="carousel-inner" role="listbox">
<div class="carousel-item active">
<img src="images/featured_image_grey1.jpg" alt="First slide">
</div>
<div class="carousel-item">
<img src="images/featured_image_grey2.jpg" alt="Second slide">
</div>
</div>
<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
<span class="icon-back" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
<span class="icon-next" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
和CSS：

.carousel-control {
