If you are having an issue getting your CSS borders to display in Firefox, here is the solution.

If your CSS borders do not display in Firefox, but work fine in Internet Explorer and Chrome, the solution could be very simple but easy to overlook.

I had been using the code:

border: 4 solid 268a16;

which worked perfectly in IE and Chrome, but Firefox would not display the borders no matter what I tried. I found many solutions on Google that suggested adding -moz-border-radius and -webkit-border-radius, but those did nothing to help my border issue.

You may have already tried these solutions and come up empty, like I did. As it turned out, the solution was very simple, all that you need to do was add "px" to my size parameter.

border: 4px solid 268a16;

And that solved the issue with Firefox not displaying CSS borders. Good luck and happy webmastering.
