css outline left and right

Question

Anyway to set css outline only show left and right ? Because I can't use border, I tried but it will make more bad outlook .

.test{
  margin:10px;
  padding:10px;
  width:100px;
  height:10px;
  outline:10px solid #000;
  }

<div class="test"></div>

Answer 1

You could possibly achieve this using two box shadows:

div {
  margin: 10px;
  padding: 10px;
  width: 100px;
  height: 10px;
  box-shadow: -5px 0px 0px 0px black, 5px 0px 0px 0px black;
}

<div></div>
