html div tag

The <div> tag is nothing more than a container unit that encapsulates other page elements and divides the HTML document into sections.
 The div can be used for reading purposes or to nest all the information inside the div then to style the div through css as a background card.

<div id='number1' class='model'>
  <h2>Number 1:</h2>
  <h3>Divs</h3>
  <p>
    Div's are great to split up and shape your website, they can be
    modified my css, interact with js and more.

  <!-- Eny regular html code can be put in divs, multiple classes
  can be put in divs. Yet divs can only have 1 id. Divs are so useful!-->
</div>
<!-- Hope This Helped! -->
