Again as with the previous weblog (https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/1017), this only works in IE 5.5+ 100%. Other browsers well sometimes you get a little lucky and sometimes not.
Also, credits to David J. Hark (http://www.fred.net/dhark/demos/css/css_filter_examples.html), for creating such a nice set of examples.
This example will prove to be a lot easier to implement than the previous one as you only need to add a single link to your page or if you prefer to set the value in a user preference then you'll need to activate the command on the Page Layout when the page is loaded.
Invert (#)
</textarea>

As I mentioned you can also add this into your <b>Page Layout</b> quite easily.<br>

<textarea cols="79" rows="10">
<% IF userPrefInvert EQ 'X'. %>
<script>
document.body.style.filter="invert();";
eval();
</script>
<% ENDIF. %>
</textarea>
<br>

Once a user clicks the link, or the link is activated via the preference then the page will look like...<br>
