css:

#user1  {     background-color: green; <--the 1 need change.     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>

so question how can go reading css value sql database? can write fine, thats not problem, how update value read everyone.

you can use dynamic php-css file , use cache store temporary (so request count can saved)

create php file , set header content type text/css

header("content-type: text/css; charset: utf-8"); //your sql queries goes here
