Hello
Is possibe remove content in div after visiting?
Thank you very much for your help

After visiting what?

Hospital, the toilet, your aunt maybe even the page?

And just explain a little more on what you are looking for.

AND if it is the page, the answer is: Yes it is possible but NOT with HTML.

change the div visible property with javascript

I suppose you could set an infinite cookie with JavaScript, which just tells the page that you have visited the site and therefore to not display the div.

Using some code from W3Schools, I've come up with this. It displays an alert box if you've been to the website before.

<script type="text/javascript">
//W3Schools stuff
function setCookie(c_name,value,exdays) {
	var exdate=new Date();
	exdate.setDate(exdate.getDate() + exdays);
	var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
	document.cookie=c_name + "=" + c_value;
}
function getCookie(c_name) {
	var i,x,y,ARRcookies=document.cookie.split(";");
	for (i=0;i<ARRcookies.length;i++) {
		x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
		y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
		x=x.replace(/^\s+|\s+$/g,"");
		if (x==c_name) {
			return unescape(y);
		}
	}
}
//End W3Schools stuff

var visited = getCookie("visited");
if (visited==null||visited=="") {
	window.onbeforeunload=setCookie("visited","yes",99999);
}
else {
	alert("You've been here before!");
	//Add your own JS here
}
</script>
