Vertical divider CSS

I am creating a vertical divider, that works fine. But the CSS is cumbersome.

The CSS is:

.headerDivider1 {
border-left:1px solid #38546d;开发者_StackOverflowheight:80px;position:absolute;right:250px;top:10px;
}

.headerDivider2 {
border-left:1px solid #16222c;height:80px;position:absolute;right:249px;top:10px;
}

The HTML is:

<div class="headerDivider1"></div><div class="headerDivider2"></div>

The result is:

How could I tidy the HTML and CSS up?

.headerDivider {
     border-left:1px solid #38546d; 
     border-right:1px solid #16222c; 
     height:80px;
     position:absolute;
     right:249px;
     top:10px; 
}

<div class="headerDivider"></div>

<div class="headerdivider"></div>

and

.headerdivider {
    border-left: 1px solid #38546d;
    background: #16222c;
    width: 1px;
    height: 80px;
    position: absolute;
    right: 250px;
    top: 10px;
}

for vertical divider only

.divider {
  border-left: 1px solid #000;
  height: 100%;
}

I prefer using the after property for vertical divider using CSS because it's neither content nor a border.

.block {
  position: relative; /* ADDED */
}

.block:after {
  content: '';
  position: absolute;
  border-left: 1px solid black;
  right: -10px; 
  height: 80%; 
}

.block:last-child:after {
  display: none; /* Hide the divider for the last block */
}
