jquery - Bootstrap Modal 是透明的 - 不透明度不起作用

Question

我正在使用 Bootstrap 和 Modals atm，但不知道我做错了什么

如您所见，Modals Content 是透明的，看起来不太好......
那么我能做些什么呢？

<div id="changeRPGNameModal" class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-hidden="true">
    <div class="modal-dialog modal-sm">
        <div class="modal-content">
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <h4 class="modal-title">Name ändern:</h4>
        </div>
        <div class="modal-body">
            <div class="form-group">
                <label for="inputRPGName">Name</label>
                <input type="text" class="form-control" id="inputRPGName"
                       placeholder="Gib einen neuen Namen ein" autofocus/>
            </div>
            <div class="containerButtons">
                <button class="floatLeft btn btn-default btn48Percent" data-dismiss="modal">Abbrechen</button>
                <button class="floatRight btn btn-success btn48Percent" data-dismiss="modal" id="buttonChangeRPGName">Ändern</button>
            </div>
            <div class="clear"></div>
        </div>
    </div>
</div>

我已经尝试在 .modal-backdrop(.fade.in) 上设置不透明度，但如果我这样做，我屏幕的整个背景都会变白

好了，您已经关闭了 <div class="modal-content">在内容加载之前，内容加载到模态主体之外，Opacity not working , 我还添加了 <div class="modal-content">模态标题。

<div id="changeRPGNameModal" class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-hidden="true">
<div class="modal-dialog modal-sm">
    <div class="modal-content">
        <div class="modal-header">            
                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
                <h4 class="modal-title">Name ändern:</h4>
        </div>
        <div class="modal-body">
            <div class="form-group">
                <label for="inputRPGName">Name</label>
                <input type="text" class="form-control" id="inputRPGName"
                       placeholder="Gib einen neuen Namen ein" autofocus/>
            </div>
            <div class="containerButtons">
                <button class="floatLeft btn btn-default btn48Percent" data-dismiss="modal">Abbrechen</button>
                <button class="floatRight btn btn-success btn48Percent" data-dismiss="modal" id="buttonChangeRPGName">Ändern</button>
            </div>
            <div class="clear"></div>
        </div>
    </div>
</div>
</div>      
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#changeRPGNameModal">Open Modal</button>
