how to add vertical line between two divs

Question

I want to make a vertical line between two divs. we have hr for horizontal line but none for vertical line as I know. Is there anyway to make it without using border?

<style>
#wrapper_1 {
    background-color:pink;
    height:100px;
    float:left;
    width: 100px;
}

#wrapper_2 {
    background-color:brown;
    height:100px;
    width: 100px;
    float:right;
}
</style>

<div id="wrapper_1">
    Creating slideshows PHP
</div> 

<div id="wrapper_2">
    Creating slideshows with WordPress 
</div>

You can also use pseudo elements to make a vertical separator. You don't need an extra div to make a separator just use the pseudo elements and style it according to your needs.

#wrapper_1 {
  background-color: pink;
  height: 100px;
  float: left;
  width: 100px;
}
#wrapper_1:after {
  content: "";
  background-color: #000;
  position: absolute;
  width: 5px;
  height: 100px;
  top: 10px;
  left: 50%;
  display: block;
}
#wrapper_2 {
  background-color: brown;
  height: 100px;
  width: 100px;
  float: right;
}

<div id="wrapper_1">

</div>

<div id="wrapper_2">
  Creating slideshows with WordPress
</div>

PS: Beware of the absolute positioning of the pseudo elements. Thanks.
