hello again, watusiware!
sorry, but we somehow use different wavelengths.by playground i meant an online service, like jsbin.
that's what their authors call it. or authors of something similar.
what i am looking for is something similar, but a solution in which i do not need to paste the
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="viewport" content="width=320; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;">
<title></title>
<link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/jquery.mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<link rel="stylesheet" href="my2.css" />
<style></style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js">
</script>
<script src="https://ajax.aspnetcdn.com/ajax/jquery.mobile/1.2.0/jquery.mobile-1.2.0.min.js">
</script>
<script src="myJS3.js">
</script>
</head>
in the html, but which can be set to make use of the above libs by default.
thus, the html window could be reserved for the content of <body>.
I hope it is clear now.
