我写了这个JQuery / JavaScript来将一个菜单滑入网站，然后身体移开了，但身体似乎并没有移开。菜单确实滑入，只有身体没有。我发布了所有JavaScript，HTML和CSS。
var main = function(){
$('.icon').click(function()
{
$('.menu').animate({
left: "0px"
}, 200);
$('body').animate({
left:"300px"
}, 200);
});
};
$(document).ready(main);@charset "utf-8";
body {
background-image: url(http://wallpapercave.com/wp/U7rb02o.jpg);
background-size: cover;
left: 0px;
position: relative;
margin: 0px;
overflow: hidden;
top: 0px;
right: 0px;
bottom: 0px;
}
.menu {
background-image: url((https
://image.freepik.com/free-vector/white-cubes-pattern_1053-248.jpg))
background: url("https://image.freepik.com/free-vector/white-cubes-pattern_1053-248.jpg");
background-repeat: repeat;
background-position: left top;
background-image: url(http://wallpapers.ae/wp-content/uploads/2014/10/Black-Pattern-Background-Wallpaper.jpg);
height: 100%;
width: 300px;
position: fixed;
left: -300px;
cursor: pointer;
}
.icon {
padding-top: 25px;
padding-right: 0px;
padding-left: 25px;
padding-bottom: 25px;
width: 75px;
cursor: pointer;
height: 40px;
