how to add a css class for all elements that has particular style

Question

I wan to add a css class for all elements that has particular style.

Eg. if there are 5 elements that with the style "float:left".

I want to remove the "float:left" and add "align-left" class.

please help me

Answer 1

The way to do it is to use filter() like below, but the target selector * is a bad one, so try to have better selector to target the desired elements

$('*').filter(function () {
    return this.style.float == 'left'
}).css('float', '').addClass('align-left')

Answer 2

You can also use this:

if( $("#test").css('display') == 'block') {
  // Remove and add properties here
}
