Question

我在HTML应用程序中添加了一个侧边菜单图层，引用了这个链接http://www.uiupdates.com/sidebar-menu-layer-with-jquery/。

当我按下菜单按钮＆amp;侧边菜单上诉。我的以下div类"buttoncls_scrollableCenter" & "buttoncls_fotter"能够在菜单出现时向右移动。

但是当出现侧边菜单时，此div "buttoncls_scrollable"不会向右移动。

如果出现侧边菜单，如何移动此div "buttoncls_scrollable"？

代码： -

Answer 1

您需要绝对定位buttoncls_scrollable：

div.scrollable {
    position: absolute;
    right:0;
    left:0;
}

Example

如果您还将#fotter更改为right:0而不是width:100%;，则会在侧边菜单显示时出现水平滚动条，以解决您的问题

Answer 2

为什么不使用jquery？这将非常简单。有多种方法可以做到，但你可以使用Jquery click()函数来执行操作并使用Jquery addClass()函数来提供＆＃39; body＆＃39; （或其他＆＃39;包装所有＆＃39;元素）一个类，以便在点击后影响他的所有孩子 - 菜单和新div的新位置（除了菜单本身之外的所有元素的div）。在HTML上，添加一个div，它将包装除菜单本身之外的所有元素，并在输入图像中添加一个类或id以避免冲突，例如添加一个id（id =＆＃34; menu_button＆＃34;）和用jquery调用它：

Jquery的：

$(document).ready(function(){
    $('#menu_button').click(function(){
        if ($('body').hasClass('show')){    
            $('body').removeClass('show');  
        }
        else {
            $('body').addClass('show')
        }
    });
});

在CSS上，你需要添加新的div包。添加left: 200px;（菜单的宽度）以在不需要显示菜单时完全隐藏菜单。添加z-index: 1;（您可以使用更高的值，只要它将高于需要在下面的所有其余元素）。使其菜单高于其他元素。使用left: 0;添加新类，将菜单置于单击后所需的位置。您可以使用CSS3 transition来获得更好的效果。

CSS：

.content_wrap
{
    width: 100%;
    height: 100%;
    float: right;
}

.show .content_wrap
{
    width: calc(100% - 200px);
}

.div_layer
{
     background: none repeat scroll 0 0 #3e4046;
     position: absolute;
     left: -200px;
     width: 200px;
     height: 100%;
     z-index: 1;
}

.show .div_layer
{
    left: 0;   
}

.content_wrap, .div_layer
{
     -webkit-transition: 1s;
     -moz-transition: 1s;
     transition: 1s;   
}
