html5左侧弹出菜单怎样实现
这个可以通过绝对定位，配合left设置 或者translate去实现
left的方法：
比如让class为menu的元素宽为300px，高100%的，设置left为-300px；在这期间可以加一个过渡transition:left 0.3s ...；
然后让class为menu active的元素设置 left设置为0就可以了 ，在这期间可以加一个过渡transition:left 0.3s ...；
然后可以通过Jquery的toggleClass('active');来实现切换
translate
比如让class为menu的元素宽为300px，高100%的，设置left为-300px；在这期间可以加一个过渡transition:left 0.3s ...；
然后让class为menu active的元素设置 transform:translate3d(-300px,0,0) ，在这期间可以加一个过渡transition:left 0.3s ...；
然后可以通过Jquery的toggleClass('active');来实现切换
这个过程中 需要注意 body需要overflow：hidden; (不然会有滚动条，可设置overflow-x即可)
left 和 translate 最好用translate ，translate3d可以开启GPU硬件加速，性能会更好，体验会更流畅
我github有类似小组件样式

dx html5怎样写下拉菜单
1）、普通下拉列表菜单
html代码如下：
form action="" method="get"
label1、普通下拉列表菜单/label
select name=""
option value="0"DIVCSS5/option
option value="1"DIVCSS5/option
/select
/form
2）、跳转下拉列表菜单（如常见点击后跳转到选择网站）
常常一些网站做友情链接，与部门之间使用select下拉标签实现网址跳转。下面我们通过代码与案例接受select跳转菜单应用。
跳转菜单html代码如下：
form action="" method="get"
label2、跳转的下拉列表菜单/label
select name="jumpMenu" id="jumpMenu"
onchange="MM_jumpMenu('parent',this,0)"
option value=""Rothur/option
option value=""Rothur/option
/select
/form
实现跳转还需要在head标签内加入Js脚本动作代码：
script type="text/javascript" !-- function MM_jumpMenu(targ,selObj,restore){ //v3.0 eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'"); if (restore) selObj.selectedIndex=0; } //-- /script
html5 浮动侧滑菜单栏怎样实现
一共有4种侧滑动画特效。这款CSS3菜单的特点是鼠标划过时即可以各种动画方式展开和隐藏菜单项，该动画方式由CSS3中的transition-delay属性来完成
