不能在底部保持页脚引导模式全屏

Question

我试图引导模式的页脚保持到底部，但我不能，这是我的HTML结构：

<!-- Button trigger modal --> 
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal"> 
    Launch demo modal 
</button> 

<!-- Modal --> 
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"> 
    <div class="modal-dialog"> 
    <div class="modal-content"> 
     <div class="modal-header"> 
     <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button> 
     <h4 class="modal-title" id="myModalLabel">Modal title</h4> 
     </div> 
     <div class="modal-body"> 
     ... 
     </div> 
     <div class="modal-footer"> 
     <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> 
     <button type="button" class="btn btn-primary">Save changes</button> 
     </div> 
    </div> 
    </div> 
</div> 

基本上我想显示模式在全屏模式下，这个工作良好，但是页脚并没有到底。

的CSS：

.modal-dialog { 
width: 100%; 
    height: 100%; 
    padding: 0; 
} 

.modal-content { 
    height: 100%; 
    border-radius: 0; 
} 

我创建的jsfiddle解释的情况：

Answer 1

，您可以给模型的内容绝对有底0像素的相对位置和模态英尺的位置;

尝试用

.modal-content { 
    height: 100%; 
    border-radius: 0; 
    position:relative; 
} 

.modal-footer { 
    border-radius: 0; 
    bottom:0px; 
    position:absolute; 
    width:100%; 
}

添加此行到模式页脚Fiddle 默认情况下，模态内容具有相对位置。我使用！对于课堂模式对话框中的css overrule非常重要。如果你有分离的CSS文件，那么你不需要使用！重要的。

.modal-dialog { 
 

 
    width:100% !important; 
 
    height: 100%; 
 
    margin: 0 auto !important; 
 
    padding:20px 20px; 
 
} 
 

 
.modal-content { 
 
    height: 100%; 
 
    border-radius: 0; 
 
} 
 

 
.modal-footer{ 
 
position:absolute; 
 
bottom:0; 
 
width:100%; 
 
}
