Bootstrap模态图像背景

Question

只是想问一下我的模态中是否可以有背景图像？我尝试过搜索，但我只看到模态的背景相关内容，它指的是页面本身。我想要的是我的模态框，上面有图像背景。或改变它的颜色？谢谢。我在CSS方面不是那么好。谢谢。

Answer 1

假设您想在模态体中使用图像，则可以使用

.modal-body {
   background-image: url(path/to/image);
}

或者如果你想要它在你的模态后面你可以使用

.modal-backdrop {
   background-image: url(path/to/image);
}

Answer 2

我假设您正在使用引导程序

<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.4/js/bootstrap.min.js"></script>

你需要编辑你的

<div class="modal-content">
    ...
</div>

至：

<div class="modal-content modal-popout-bg">

CSS：

.modal .modal-popout-bg {
    background-image: url("http://somepic.com/somepic.jpg");
}

Answer 3

是的，只需使用background-image: url(path/to/your/image);

$('#myModal').modal() 

.modal-body {
    background-image: url('http://myfunnymemes.com/wp-content/uploads/2015/04/Doge-Meme-Lion-In-All-Its-Majestic-Glory.jpg');
    background-repeat: no-repeat;
    background-size: cover;
    height: 400px;
}
