Okay, I have two different background .jpgs that I want to used as the backgroud depending on what time of day it is. I want the sunny background from 7am to 8pm and the night background from 8pm to 7am.
I'm working on a remote html file and I have the backgrounds and graphics stored on a separate server from the actual html file. Most of the css is in the html file except for the the body section that contains the background code which I separated and moved to an external style sheet. I made two separate style sheets, one w/ the day bg image & one with the night. This is the body css that's on the night css style sheet.
@charset "UTF-8";
/* CSS Document */
body {
background-image: url('http://itsnotch.com/tumblr/images/daytime_bg.jpg') !important;
background-repeat: repeat-x !important;
background-attachment: fixed !important;
background-position: top center !important;
background-color:#b68e59 !important;
margin-top:-5px !important;
font-family: "Lucida Sans Unicode", "Lucida Grande", sans-serif;
font-size:14px !important;
}
I've written a javascript code that I thought would work. But it didn't. I placed it right below the and it still didn't work. Why didn't it work? I just want to be able to switch the background out... time-sensitively.
<script type="text/JavaScript">
<!--
function getStylesheet() {
var currentTime = new Date().getHours();
if (7 <= currentTime&¤tTime < 20) {

}
else {
document.write("<link rel='stylesheet' href='http://itsnotch.com/tumblr/files/nighttime.css' type='text/css'>");

}
}
getStylesheet();

I'd recommend something slightly different than neo - rather than setting the image only, have two CSS classes, one for day and one for night - both can be in the same stylesheet. You can set the body's class depending on the time of day. This will allow you to do more than just the background.
document.body.className = "day";
or
document.body.className = "night";
You don't need to use a new stylesheet for each image. You can change only the background image from javascript:
<html>
<head>
<title></title>
</head>
<body>
</body>
<script type="text/javascript">
var currentTime = new Date().getHours();
if (document.body) {
if (7 <= currentTime && currentTime < 20) {
document.body.background = "http://itsnotch.com/tumblr/images/daytime_bg.jpg";
}
else {
document.body.background = "http://itsnotch.com/tumblr/images/nighttime_bg.jpg";
}
}
</script>
</html>
EDIT: updated to show the recommended location of the script inside the page. This has been tested and works in Firefox and Internet Explorer.
