Anti-Social Behaviors

Is your browser anti-social? Here is a simple test.

Overview

Trying to find a sneaky way of loading behavioral extensions (JavaScript) into IE7, I toyed with the following JavaScript embedded in a CSS style sheet:

html{behavior:expression(function(element){
 // do something

 // trash this expression
 runtimeStyle.behavior = "none";
}(this))}

Well I said it was sneaky.

There are other CSS hacks similar to this. This differs from those I’ve encountered in the past in three ways:

• it uses the behavior property instead of the usual background property
• it uses expression() in place of url()
  this avoids use of the javascript: protocol which messes up on secure servers (https://)
• Finally, we trash the expression after it has executed
  this saves the expression from being endlessly evaluated.

I had to abandon (for now) this approach because I couldn’t get it to work in IE5.0. Oh well.

Shame to waste it though...

Browse Happy Popup

current version: 1.0.4

Upon exiting your site, visitors using Microsoft Internet Explorer 6.0 will experience an annoying DHTML popup window advising them to upgrade to a better browser. Other browsers will not be affected.

Remember. This only works on Internet Explorer 6.0 (nothing happens in other browsers).

examples:

• Internal link: nowhere
  there’s nothing there...
• External link: Living Can Kill You
  don’t forget to come back!
• External link: Glazblog

Just include a link to the noIE.css style sheet in your web pages and all Explorer users will be prompted to upgrade their browser when they exit your site. Because all the code is contained in a style sheet there is no additional configuration.

The popup itself exists as a separate HTML file that you can restyle for your pleasure. :-)
