【问题标题】：Make twitter Bootstrap popup modal slide and stick to bottom of page制作 twitter Bootstrap 弹出模式幻灯片并粘贴到页面底部
【发布时间】：2014-12-23 06:21:32
【问题描述】：

我正在使用 bootstrap 2.3，我有一个模态框，它会在几秒钟后从页面底部滑动，我希望它粘在屏幕底部。一切正常，除了当您调整浏览器高度时，模式不会粘在底部。请帮忙！

这是弹出窗口的样子：https://www.dropbox.com/s/kn257b07hdle52i/Screenshot%202014-10-27%2016.09.12.png?dl=0

它会一直持续到您调整窗口大小，然后是：https://www.dropbox.com/s/r0x4mkpj9xvsu61/Screenshot%202014-10-27%2016.10.00.png?dl=0

【解决方案1】：

问题出在您的 CSS 中。您需要设置底部属性而不是顶部属性以获得您想要的结果，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。

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 -->

这很完美，但是如果我想将 localStorage 设置为 24 小时呢？
