JavaScript。それを制御します イベント:

var toggle = document.getElementById("toggleMenu");        var list = document.getElementById("list");        var hide = document.getElementById("hide");        var show = document.getElementById("show");        var isHidden = true;        window.onload = function() {            toggle.onclick=function(){                if(isHidden){                    list.style.left="0px";                    isHidden = false;                    hide.style.opacity=0;                    this.style.mozTransform = "rotate(180deg)";                    this.style.msTransform = "rotate(180deg)";                    this.style.oTransform = "rotate(180deg)";                    this.style.webkitTransform = "rotate(180deg)";                    this.style.transform = "rotate(180deg)";                    show.style.opacity=1;                }else{                    list.style.left="-200px";                    isHidden = true;                    hide.style.opacity=1;                    this.style.mozTransform = "rotate(0deg)";                    this.style.msTransform = "rotate(0deg)";                    this.style.oTransform = "rotate(0deg)";                    this.style.webkitTransform = "rotate(0deg)";                    this.style.transform = "rotate(0deg)";                    show.style.opacity=0;                }            }        }
