All answers forget one thing: he asks about the element of highest left value, not the max value among elements.
So:
window.load(function()
{
var max = 0, $element;
$('.elements').each(function()
{
if($(this).offset().left > max)
{
max = $(this).offset().left;
$element = $(this);
}
}
}
At the end, $element
will have the element with highest left value
