How to make the middle of 2 divs resizable to change sizing? (am using bootstrap 4)

Question

I have the following layout:

I want to make it so that the user can put their cursor in the middle of content1 and content2 and be able to drag it left and right to resize it (making content1 bigger/content2 smaller. Is there a way to do this with my current code?

CSS

body{
  height: 100%;
  width: 100%;
}
.main-wrapper{
  background-color: #f5f5f5;
  height: 100%;
  left: 0;
  padding-bottom: 50px;
  padding-top: 50px;
  position: fixed;
  top: 0;
  width: 100%;
}
@media (max-width: 991px){
  .main-wrapper{
    overflow-x: hidden;
    overflow-y: auto;
  }
}
.header-wrapper{
  background-color: #009688;
  color: white;
  height: 50px;
  width: 100%;
}
.footer-wrapper{
  background-color: #121212;
  color: white;
  height: 50px;
  width: 100%;

        <p>Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.

Answer 1

Well, I don't think you can do this with only pure HTML and CSS properties. Use the Jquery resizable() that allows you to resize divs by draggin.

<script>
   $( function() {
      $( "#divID" ).resizable();
   } );
</script>`
