css width: calc(100% -100px); alternative using jquery

Question

If you have a browser that doesn't support the calc expression, it's not hard to mimic with jQuery:

$('#yourEl').css('width', '100%').css('width', '-=100px');

It's much easier to let jQuery handle the relative calculation than doing it yourself.

I think this may be another way

    var width=  $('#elm').width();

    $('#element').css({ 'width': 'calc(100% - ' + width+ 'px)' });

100%-100px is the same

div.thediv {
  width: auto;
  margin-right:100px;
}

With jQuery:

$(window).resize(function(){
  $('.thediv').each(function(){
    $(this).css('width', $(this).parent().width()-100);
  })
});

Similar way is to use jQuery resize plugin

Try jQuery animate() method, ex.

$("#divid").animate({'width':perc+'%'});
