HTML

a = 10<br/>
b = 99<br/>
Result: 
<p>a = <span id="a"></span></p>
<p>b = <span id="b"></span></p>

CSS

span {
    color: #f00;
}

JavaScript

// helper function for displaing results
var output = function(operator, result) {
    document.getElementById(operator).innerHTML = result;
}

// variables
var a = 10;
var b = 99;

// a^=b, b^=a, a^=b - swap variables using XOR operation, 
// details: http://en.wikipedia.org/wiki/XOR_swap_algorithm
a^=b, b^=a, a^=b;
output('a', a);
output('b', b);
