<!-- This is opening of a division tag-->
</div><div style="background-color:lightblue">
  <h3>This is a heading</h3>
  <p>This is a paragraph.</p>
 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.  <html>
.myDiv {
  border: 5px outset red;
  background-color: lightblue; 
  text-align: center;


<div class="myDiv">
  <h2>This is a heading 
  in a div element</h2>
  <p>This is some text in a div element.</p>


 <div></div>    div {  display: block;}
