Forward and Back Buttons
For what ever reason perhaps just nostalgia possibly because I happen to use them more than expected, I have forward and back links on my website. The buttons are JavaScript powered and I have had "noscript" tags warning users of their lack of functionality since I added the links years ago. However, I don't like that they still exist without scripting. Anyway, I decided that I was going to use scripting to draw the buttons.
<script type="text/javascript"> document.write('\x3Ca href="javascript:history.back()">Back\x3C/a>'); document.write('\x3Ca href="javascript:history.forward()">Forward\x3C/a>'); document.write('\x3Chr />'); </script>
Note: that by using 'x3C' rather than '<', I eliminated a potential problem in the parsing of the page and made it so that they would validate again.
