How do I create a triangle between two divs? CSS

Question

I would like to create a triangle like the one below:

however, I'm not quite sure how to get the triangle between the divs.

Here's the code I currently have:

.container {
  display: flex;
  flex-direction: row;
  align-content: center;
}
.box {
  height: 50px;
  width: 50%;
  background-color: #ddd;
  border: 1px solid red;
}

There must be better ways, but I usually do something along these lines:

.container {
  display: flex;
  flex-direction: row;
  align-content: center;
}

.box {
  height: 50px;
  width: 50%;
  background-color: #ddd;
  border: 1px solid red;
}

.triangle {
  position: relative;
}

.triangle::before {
  content: "";
  width: 10px;
  height: 10px;
  border-top: 2px solid red;
  border-right: 2px solid red;
  background: #ddd;
  transform: rotate(45deg);
  position: absolute;
  top: 50%;
  right: -7px;
  margin-top: -5px;
}

You can use this css property to get the desired structure.

.container {
  display: flex;
  flex-direction: row;
  align-content: center;
}
.box {
  height: 50px;
  width: 50%;
  background-color: #ddd;
  border: 1px solid red;
  position:relative;
}
.box-arrow{
  position:absolute;
 right:-.6rem;
 z-index:2;
 top:50%;
 transform:translateY(-50%);
     width: 0.6rem;
    height: 1rem;
    
}
.box-arrow::after{
    z-index:3;
    position: absolute;
    display: block;
    content: "";
    border-color: transparent;
