Jquery if then statement for css value

Question

I want to check whether a div with a CSS class="x" has height="auto"

If yes I want (with a jQuery script) the css-class="a" removed from all elements with the css-class="y"

If not the script does not have to do anything. Thanks

Answer 1

if ($('div.x').css('height') === 'auto') {
    $('.y').removeClass('a');
}

Answer 2

$(document).ready(function(){
  if ($('div.x').css('height') === 'auto') {
    $('.y').removeClass('a');
  }   

});

You may need to do that within a each() call
