Q: Isotope JS Library - Cards overlapping I have integrated the Isotope grid .js library (https://isotope.metafizzy.co/index.html) with my Wordpress posts to display a nice grid: see screenshot below:

However, on initial load (and when I do a cache reload) the grid items seem to overlap. See below Screenshot: 

I've enqueued the js library using a CDN, I can tell thats working. I have the below code. Firstly the loop to bring in the posts and then the bit of Javascript that initialises it.
<div class="container blog-card-container">
    <div class="grid">

        <?php

        $my_query = new WP_Query('cat=[14]&posts_per_page=10');

        ?>

        <?php while ($my_query->have_posts()) : $my_query->the_post(); $do_not_duplicate = $post->ID;?>

                    <div class="grid-sizer"></div>

                    <!-- Conditional a Link =========================================== -->

                    <?php 
                      if(get_field('quote') == ''){
                      $yourTag = "<a href='".get_the_permalink()."'>" ;
                      } else {
                      $yourTag = "";
                      }
                    ?>


                    <div> <?php echo $yourTag; ?> </div>
                            <div class="grid-item">

                                <div class="client-header-logo-card" style="background-color: <?php the_field('client_brand_colour'); ?>;">
                                    <?php 

                                    $image = get_field('client_logo');

                                    if( !empty($image) ): ?>

                                        <img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />

                                    <?php endif; ?>
                                </div>

                                <div class="clients-card-block">

                                        <div class="embed-container">

<script type="text/javascript">

// vanilla JS
var grid = document.querySelector('.grid');
var iso = new Isotope( grid, {

  itemSelector: '.grid-item',
  percentPosition: true,
  masonry: {
    columnWidth: '.grid-sizer',
    gutter: 20
  }
});

// layout Isotope after each image loads
$grid.imagesLoaded().progress( function() {
  $grid.isotope('layout');
});

</script>

I included this little bit of javascript after the init which is supposed to fx the issue, but I find them still overlapping: 
// layout Isotope after each image loads
$grid.imagesLoaded().progress( function() {
  $grid.isotope('layout');
});

My site is here by the way: http://webserver-meetandengage-com.m11e.net its around halfway down the homepage.
Do you think this is because I've included the javascript on the same page? Should I include it in it's own .js file? I tried this initially but I couldn't get it to work properly...

A: Seems you didn't include imagesLoaded plugin on the page. Please make sure that the plugin is added properly. Hope that'll resolve the overlapping issue. And you should add this <div class="grid-sizer"></div> outside the loop.
