OK guys, you're talking about C, C++, PHP here, but now I have question about CSS for web style. This code :

A.menulink1 {
   	font-size : 11px;
   	font-family : Arial, sans-serif;  
   	text-decoration : none;
   	color: #00407C; 
}
A.menulink1:visited {
   	color: #00407C;
	text-decoration: none; 
}
A.menulink1:active {
   	color: #E2EDF9;
	text-decoration: none; 
}
A.menulink1:hover {
   	color: #f74ae5;
	text-decoration: none; 
}

are for link, but I don't know how to make the text (link) as bold with this CSS. I don't know what I should write in the CSS. Can you get me the code to make it BOLD?

Thanks in advance.
