  display: block;
  margin-right: 1.875vw;
  width: 100%;
}

.container {
  align-items: center;
  align-content: center;
  text-align: center;

Answer 1

在您的h2:before 和h2:after 上使用flex-grow: 1; 而不是width: 100%; 将解决此问题。

h2 {
    align-items: center;
    display: flex;
    font-size: 3.125vw;
    margin-top: 0;
    position: relative;
    width: 100%;
}

h2:after {
    border-top: 1px solid #000;
    content: "";
    display: block;
    margin-left: 1.875vw;
    flex-grow: 1;         /* <--- Replace */
}

h2:before {
    border-top: 1px solid #000;
    content: "";
    display: block;
    margin-right: 1.875vw;
    flex-grow: 1;         /* <--- Replace */
}

.container {
  align-items: center;
  align-content: center;
  text-align: center;
  display: flex;
  flex-direction: column;
}

<div class="container">
  <h2>precision</h2> 
</div>
