css arrows as a before and after pseudo element

Question

In my code below I have two arrows pointing at my SoMe div, the arrows are attached to the border as long as the page is not resized.

When resized it becomes a space between the arrows and the border. I was hoping I could add the arrows as a before and after pseudo element, instead of using media queries. But I have not manged to make the arrows appear when changing the arrow classes to div.front-some:before and div.front-some:after.

Is this possible to achieve at all, or is media queries my only option?

  body {
   background: green;
 }

 h1.title {
   color: red;
   text-align: center;
   text-transform: uppercase;
   letter-spacing: 20px;
   background: green;
   max-width: 70%;
   margin: -40px auto 0 auto;
 }

 div.inner {
   border: 4px solid red;
   color: #fff;
   padding: 15px 50px 50px 50px;
   margin-top: 100px;
   box-sizing: content-box;
 }

 div.some {
   text-align: center;
   background: green;
   max-width: 40%;
   margin: 0 auto -60px auto;
 }

 .arrow-right {
   border-right: 5px solid red;
   border-bottom: 5px solid red;
   width: 25px;
   height: 25px;
   transform: rotate(-45deg);
   margin-bottom: -25px;
   margin-left: 26.5%;
 }

 .arrow-left {
   border-left: 5px solid red;
   border-top: 5px solid red;
   width: 25px;
   height: 25px;
   transform: rotate(-45deg);
   margin-top: 37px;
   margin-right: 26.5%;
   float: right;
 }

<div class="inner">


  <h1 class="title">Hello World</h1>

  <div class="arrow-right"></div>
  <div class="some"> SoMe

  </div>
  <!-- .social-icons -->
  <div class="arrow-left"></div>


</div>

Pseudo elements require the `content` property (`content: ""`). When I add this along with `display: block` the arrows display. — Turnip, Jan 07 '19 at 16:29

The psuedo selector will not appear without content: ''.

Try the following. The red arrow will appear.

.arrow-left:before {
  border-left: 5px solid red;
  border-top: 5px solid red;
  width: 25px;
  content: '';
  height: 25px;
  transform: rotate(-45deg);
  margin-top: 37px;
  margin-right: 26.5%;
  float: right;
}
