For example if i have
<style type='text/css' id='divcolorgreen'>
div{
color: green;
}
</style>
I can disable the css rule using 3 ways
Is there any easier way to disable/remove the css rule?

This is the purpose of classes. By assigning a class eg. to the <body> tag, you get the same functionality:
<style type='text/css' id='divcolorgreen'>
body.divcolorgreen div{
color: green;
}
</style>
And then if <body> looks like this:
<body class="divcolorgreen">
...
</body>
the rule is applied. To disable the rule, remove the mentioned class:
<body>
...
</body>
OK, so you are trying to change the color of all divs on a page.
jQuery has .css() which lets you set the style of all elements that match the selector. In your case, it's just div.
To set:
$('div').css('color', 'yellow');
To remove:
$('div').css('color', '');
If you don't want to use jQuery, the idea is the same:
document.getElementsByTagName('div') gives you all divs on the page. You can loop through them and change their style by elem.style.color="yellow";
