Use mootools to dynamically add CSS style sheet code, compatible with various browsers

But this is not conducive to plug-in transplantation, so I wrote this function to dynamically generate CSS. CopyCodeThe Code is as follows: addcss = function (c ){
VaR sty = Document. createelement ('style ');
Sty. type = 'text/CSS ';
If (browser. ie ){
Sty.stylesheet.css text = C;
} Else {
VaR frag = Document. createdocumentfragment ();
Frag. appendchild (document. createtextnode (c ));
Sty. appendchild (frag );
}
Document. getelementsbytagname ('head') [0]. appendchild (STY );
};
Addcss ('a {background-color: red; color: black; padding: 20px ;}');

As shown above, the Code is a simple function. You can directly add code using addcss when necessary.
Note: I have tested this function in IE6, 7, 8, 9, and Firefox.
