else div1.style.display='block';
if(div2.style.display=='block') div2.style.display='none';
else div2.style.display='block';
}
function showAndHidden2(){
var div3=document.getElementById("div3");

if(div4.style.visibility=='visible') div4.style.visibility='hidden';
else div4.style.visibility='visible';
}
</script>
</head>
<body>
<div>display：元素的位置不被占用</div>
<div id="div1" style="display:block;">DIV 1</div>
