    Help with what code does

    Hello people,

    I am trying to figure out how to use Isotope and Wordpress! So far I am quite lost but managed to get a simple page kind of working for Isotope!

    I need to know what this line of code does and how it works so I can adapt it to control when the class width2 is added.

    The main line of code that is confusing me is: if ( number % 7 % 2 === 1 ) {

    Also this means I need to add a class of .number with a number inside to make some blocks a different size.

    Code:
    $(function(){
          
          var $container = $('#container');
    	  
    	  // add randomish size classes -
          $container.find('.item').each(function(){
            var $this = $(this),
                number = parseInt( $this.find('.number').text(), 10 );
            if ( number % 7 % 2 === 1 ) {
              $this.addClass('width2');
            }
            if ( number % 3 === 0 ) {
              $this.addClass('height2');
            }
          });
          
          $container.isotope({
    		  itemSelector: '.item',
    		  masonry : {
    			  columnWidth: 240
    			}
          });
          
    });
    Here is the other code if this helps but you will need to download Isotope.

    HTML Code:
    <div id="container">
      <div class="item"><p class="number">20</p></div>
      <div class="item"><p class="number">2</p></div>
      <div class="item"><p class="number">2</p></div>
      <div class="item"><p class="number">3</p></div>
      <div class="item">...</div>
      <div class="item">...</div>
      <div class="item">...</div>
      <div class="item">...</div>
      <div class="item">...</div>
      <div class="item">...</div>
    </div>
    Code:
    .item {
    	width:200px;
    	height:200px;
    	background:#f00;
    	margin:10px;
    }
    .width2 {
    	width:420px;
    	height:420px;
    }
    
    /**** Isotope Filtering ****/
    
    .isotope-item {
      z-index: 2;
    }
    
    .isotope-hidden.isotope-item {
      pointer-events: none;
      z-index: 1;
    }
    
    /**** Isotope CSS3 transitions ****/
    
    .isotope,
    .isotope .isotope-item {

          -ms-transition-duration: 0.8s;
           -o-transition-duration: 0.8s;
              transition-duration: 0.8s;
    }
    
    .isotope {
      -webkit-transition-property: height, width;
         -moz-transition-property: height, width;
          -ms-transition-property: height, width;

              transition-property: height, width;
    }
    
    .isotope .isotope-item {

          -ms-transition-property:     -ms-transform, opacity;
           -o-transition-property:      -o-transform, opacity;
              transition-property:         transform, opacity;
    }
    
    /**** disabling Isotope CSS3 transitions ****/
    
    .isotope.no-transition,
    .isotope.no-transition .isotope-item,
    .isotope .isotope-item.no-transition {

         -moz-transition-duration: 0s;
          -ms-transition-duration: 0s;
           -o-transition-duration: 0s;
              transition-duration: 0s;
    }

    In arithmetic, the Euclidean division is the conventional process of division of two integers producing a quotient and a remainder. The operator % give the remainder of division of number by n with something like number % n.

    Then if (number % 3 === 0) is true if number is a multiple of three.

    The condition number % 7 % 2 === 1 seems a little more subtle.
    Its true if (number % 7) % 2 === 1 or number % 7 is odd.

    For the first integers, its is true for the following blue integers

    0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23...
    Its is true sensibly once every two but with exceptions (twice false) after the third realization...

    Hope that help

    Thank you very much for your reply. I have more of an idea of what the script is doing.

    I think I need to locate a better way and just add classes at random to create my different sized divs.

    Thank you.

    To randomly select classes or widths, you can write :

    Code:
    // a class from N (cl0, cl1, cl2 ... clN-1)
    var N=10;
    var myRandomClasse='cl'+Math.floor(Math.random()*N);
    
    // but you can to choose a with or height between min and max pixels with
    var min=100,max=400;
    var myRandomWidth=(min+Math.floor(Math.random()*(max-min+1))+'px';
    
    // or to chose among different widths
    var myWidth=[100,110,120,130,140,150,160,170,180,190,200];
    var myRandomWidth=myWidth[Math.floor(Math.random()*myWidth.length)]+'px';
