I've reached a dead end with this issue. Here's the current situation: When User 1 clicks "not available," the background of a div turns red and updates on all other users' screens.
CSS:
#User1
{
background-color: green; <--This is the part I need to modify.
height: 40px;
width: 40px;
margin-left:-8px;
margin-top:-8px;
}
HTML:
<!DOCTYPE HTML>
<html>
<head><link href="css/HTML.CSS" rel="stylesheet"><meta http-equiv="refresh" content="5"></head>
<body>
<div id="User1"></div>
</body>
</html>
My question is, how can I retrieve the CSS value from my SQL database? I am able to write to it without any issues, but I'm not sure how to make it update so that everyone can read the new value.
Thank you for any assistance.
