Shortcode not staying inside div tag
Maybe your form has a float property. So just add overflow hidden to parent div. Take a look here: https://codepen.io/zecka/pen/jObvbmG your code can be like that: <div style=”border: 3px solid green; margin-top: 1em; height: auto; overflow: hidden”> <h2>Blog notifications</h2> <?php echo do_shortcode(‘[forminator_form id=”9979″]’); ?> </div>
