smonkey Paranoid (IV) Inmate From: Northumberland, England Insane since: Apr 2003	posted 09-01-2003 14:43 Hi guys, I have been using CSS a lot recently and have discovered soem cool things, but one thing stopping me from implementing these cool things is that IE only supports the :hover pseudo-class on 'a' objects. So what I want to do is figure out a way to seamlessly implement in IE any references to :hover using the onMouseOver event. But firstly I need a way to check objects to see if a :hover pseudo-class is attached, and if it is and the browser is IE then get the :hover css attributes and apply them using javascript access to teh style properties of objects. I think it can be done without upsetting standard page code too much - but then there may be a huge gaping hole in my understanding of js (in fact I knwo there is). Get thinking people if it ain't too much trouble, Thanks guys, Jon visit my CryoKinesis Online Gallery

smonkey Paranoid (IV) Inmate From: Northumberland, England Insane since: Apr 2003	posted 09-01-2003 20:04 ok imagine this: code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <style> .bob { background: blue; width: 100px; height: 100px; } .bob:hover { background: red; } </style> </head> <body> <div class="bob"> yada yada yada </div> </body> </html> Now in Opera and Mozilla and Safari, the blue square div with the class of 'bob' will go red if you mouseover it. But in IE this does not happen because the class of bob is applied to a 'div' object rather than an 'a' link object. So the easy workaround for IE would be to add an 'onMouseOver' event to the 'div' that dynamically changes the the background style attribute to red on mouse over and then an 'onMouseOut' event to change it back to blue on mouse out. But that would mean I would have to go into the html code and add those lines, or define the 'div' and assign the 'onMouseOver' event script in the head of the page. What I want to do is create a script that checks the style attributes of objects in the page, and if it finds an element which has a ':hover' pseudo-class declared for it, then the script would substitute the that :hover event (that doesn't work in IE) with the javascript 'onMouseOver' event that does. This would require a method of checking page objects for css style/class/id properties etc. Can this be done, and are any of you clever enough to figure out how?

Get thinking people if it ain't too much trouble,

ok imagine this:

code:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 

"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<head>

<style>

.bob {

        background: blue;

        width: 100px;

        height: 100px;

}

.bob:hover {

        background: red;

}

</style>

</head>

<body>

<div class="bob">

yada yada yada

</div>

</body>

</html>

Now in Opera and Mozilla and Safari, the blue square div with the class of 'bob' will go red if you mouseover it.

But in IE this does not happen because the class of bob is applied to a 'div' object rather than an 'a' link object.

So the easy workaround for IE would be to add an 'onMouseOver' event to the 'div' that dynamically changes the the background style attribute to red on mouse over and then an 'onMouseOut' event to change it back to blue on mouse out.

But that would mean I would have to go into the html code and add those lines, or define the 'div' and assign the 'onMouseOver' event script in the head of the page.

This would require a method of checking page objects for css style/class/id properties etc.

Can this be done, and are any of you clever enough to figure out how?
