Не знаю, почему мой модаль не появится на странице загрузки

-1

Я начинаю кодирование для хобби. Кажется, я не могу заставить модальное всплывать при загрузке страницы. Я открываю пустой документ, и он загружается просто отлично. Попытка загрузить его на домашнюю страницу моих друзей, и ничего не происходит. Я работаю над Dreamweaver CC.Не знаю, почему мой модаль не появится на странице загрузки

HTML:

<!-- The Modal --> 
<div id="myModal" class="modal"> 
    <!-- Modal content --> 
    <div class="modal-content"> 
     <div class="modal-header"> 
      <span class="close">&times;</span> 
      <h2>Update</h2> 
     </div> 
     <div class="modal-body">
