我试图通过单击具有 runmenu 类的 span 来通过 jQuery 动画从右侧显示一个菜单，但它不起作用，我做了同样的button 的类并且它工作正常，这里的问题是什么以及为什么它仅适用于 button？!
$(document).ready(function() {
$(".runmenu").click(function() {
$(".menu").animate({
"right": 0
}, 1000);
});
});/* Global*/
.conatianer {
width: 1026.66px;
}
/*End global*/
/*Start navbar*/
.navbar {
position: relative;
background: url(http://vividmarketinginc.com/wp-content/uploads/2015/08/1672___selected7.jpg);
background-size: cover;
height: 700.531px;
overflow: hidden;
}
.navbar .menu {
position: absolute;
right: -200px;
width: 200px;
height: 700px;
background-color: gray;
color: white;
}
.navbar .overlay {
position: absolute;
background-color: rgba(0, 0, 0, .2);
width: 100%;
height: 700.531px;
z-index: 1;
}
.navbar .navbar_one,
.navbar .navbar_two {
position: relative;
z-index: 2;
}
.navbar .navbar_one h3 {
float: left;
margin-top: 0;
color: #FFF;
padding: 20px;
text-transform: capitalize;
}
.navbar .navbar_one div {
float: right;
margin-right: 10px;
color: #FFF;
padding: 20px;
}
.navbar .navbar_two {
text-align: center;
padding-top: 230px;

.navbar .navbar_two i {

.navbar .navbar_two h1 {

这都是关于 z-index 属性的，您的 javascript 没有任何问题。您的 span.runmenu 不可点击，因为 navbar2 block 位于 span 之上。更改 css 并解决问题。
给
.runmenu {
z-index: 999;
cursor: pointer;
}
.navbar .navbar_two {
z-index: 0;
}
参见 fiddle
