@taragrg : For some reason i believe it may be some kind of syntax error. I suggest you either: A.) Upload your page to a server and post the link for us to see. B.) Copy ALL of your code and go to this website to convert characters. Once converted, come back to this forum, paste your new code, and wrap said new code inside of pre and code tags.
The reason for this is so we can see exactly what you are doing because even though @SgtLegend have some great advice and @kevin11189 even gave you a working example, i believe you are missing something.
Better yet, validate your html with the W3C tool.
