Change The Style Of An Input Box In IE7 On Focus?

I've read posts here and on Google telling me I need to set the style by hand onfocus() and onblur(). However, everything I try isn't working!

Here is my jQuery

$(document).ready(function(){
if (jQuery.browser.msie === true) {
$("input.date-picker").each(function(i)
{
var $foo= $(this);
$foo.bind('onfocus onblur', function() {
$(this).toggleClass('smalltxt-active');
});
});
}//end if
});


The a corresponding box

<input name="ctl00$SelectionContent$Selections1$txtDestinationDate" type="text"
id="ctl00_SelectionContent_Selections1_txtDestinationDate" class="date-picker"
style="width:80px;" />

I have already confirmed that my code is detecting MSIE. That I am getting a count of 2 input.date-picker objects.
