I am just learning HTML and CSS and I didn't know where to post this problem. I made an html file which was validated with no errors and a stylesheet which was also validated with no errors and tried to test them out. I linked the two together with the code <link type="text/css" rel="stylesheet" href="style.css"/> in the head element. It seems to work in chrome but not in firefox or IE. I avoid posting the entire codes due to the amount of space they would take up. If anybody needs it, I'll gladly post it.
