解决方案

问题出在你的 CSS 中.您需要设置底部属性而不是顶部属性才能获得所需的结果，但是您不能在 .modal 类上执行此操作，您需要在 .modal-body 类上执行此操作.

演示

CSS:

.modal.fade.in .modal-body {底部:0；}.modal-body {位置:绝对；底部:-250px；对:5%；填充:15px；宽度:275px；高度:250px；背景颜色:#e5e5e5；边框半径:6px 6px 0 0；-webkit-transition:底部 0.3s 缓出；-moz-transition:底部 0.3s 缓出；-o-transition:底部 0.3s 缓出；过渡:底部 0.3s 缓出；}.关闭 {边距顶部:-20px；文字阴影:0 1px 0 #ffffff;}.弹出按钮{左边距:140px；边距顶部:77px；字体粗细:粗体；}

HTML:

I am using bootstrap 2.3 and I have a modal that slides from the bottom of the page after a few seconds and I want it to stick to the bottom of the screen. Everything is working except when you resize the browser height the modal doesn't stick to the bottom. Please help!



This is what the pop-up looks like: https://www.dropbox.com/s/kn257b07hdle52i/Screenshot%202014-10-27%2016.09.12.png?dl=0

It sticks until you resize the window, then this: https://www.dropbox.com/s/r0x4mkpj9xvsu61/Screenshot%202014-10-27%2016.10.00.png?dl=0

 解决方案 
The problem is in your CSS.  You need to set the bottom property not the top property in order to get your desired result, but you can't do this on the .modal class, you need to do it on the .modal-body class.
Demo
CSS:
.modal.fade.in .modal-body {
    bottom: 0; 
}
.modal-body {
    position: absolute;
    bottom: -250px;
    right: 5%;
    padding: 15px;
    width: 275px;
    height: 250px;
    background-color: #e5e5e5;
    border-radius: 6px 6px 0 0;
    -webkit-transition: bottom 0.3s ease-out;
    -moz-transition: bottom 0.3s ease-out;
    -o-transition: bottom 0.3s ease-out;
    transition: bottom 0.3s ease-out;
}
.close {
    margin-top: -20px;
    text-shadow: 0 1px 0 #ffffff;
}
.popup-button {
    margin-left: 140px;
    margin-top: 77px;
    font-weight: bold;
}
HTML:
<div class="modal fade" id="slide-bottom-popup" data-keyboard="false" data-backdrop="false">
    <div class="modal-body">
        <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
        <p>I'm a pop sliding from the bottom that's suppose to stick</p>
        <a href="" class="btn-primary btn-plain btn popup-button">CTA</a>
    </div><!-- /.modal-body -->
</div><!-- /.modal -->
