Icon to rotate on that detail/summary which is open and clicked

When I click the second detail/summary field the icon rotates only on the first detail/summary field and not on the second.

I want the icon to rotate on that detail/summary which is open and clicked.

function changeStyle() {
    let element = document.querySelector(".rotate");
    element.classList.toggle('down');
}

.rotate.down {
    -moz-transform:rotate(45deg);
    -webkit-transform:rotate(45deg);
    transform:rotate(45deg);
}

.detail-container {
  padding-right: 100px;
  padding-left: 100px;
  width: 100%;
  min-width: 55%;
  display: flex;
  flex-direction: column;
}

summary {
  padding: 22px;
  background-color: #2d2d2d;
  margin-bottom: .4em;
  cursor: pointer;
  outline: none;
  font-size: 1.5em;
  font-family: "roboto", sans-serif;
  font-weight: 300;
}

   

 .plus {
  display: flex;
  justify-content: space-between;
}

details[open] {
  background-color: #2d2d2d;
  padding-bottom: 20px;
  margin-bottom: 10px;
}

details[open] summary {
  border-bottom: 1px solid black;
}

<div class="detail-container">
<details onclick="changeStyle()">           
  <summary>
  <div class="plus">DEFAULT TEXT <i class="fas fa-plus rotate"></i>
   </div>
   </summary>        
    <p>
    Lorem
  </p>

   </details>  
  <details onclick="changeStyle()">
  <summary>
 <div class="plus">DEFAULT TEXT<i class="fas fa-plus rotate"></i>
  </div>
   </summary>

  <p>
  Lorem
  </p>        
</details>
</div>

This "+" should rotate for 45 degrees because it is clicked but only the top one rotates

document.querySelector(".rotate") gets all the rotate elements in the document.

You need to get the element which is clicked, then find it's child that you need to rotate:

function changeStyle() {
    let element = event.target.querySelector(".rotate");
    element.classList.toggle('down');
}

function changeStyle() {
    let element = event.target.querySelector(".rotate");
    element.classList.toggle('down');
}

.rotate.down {
    -moz-transform:rotate(45deg);
    -webkit-transform:rotate(45deg);
    transform:rotate(45deg);
}

summary {
  padding: 22px;
  background-color: #2d2d2d;
  margin-bottom: .4em;
  cursor: pointer;
  outline: none;
  font-size: 1.5em;
  font-family: "roboto", sans-serif;
  font-weight: 300;
}
summary {
  list-style: none;
} 

 .plus {
  display: flex;
  justify-content: space-between;
}

details[open] {
  background-color: #2d2d2d;
  padding-bottom: 20px;
  margin-bottom: 10px;
}

details[open] summary {
  border-bottom: 1px solid black;
}
