`I have designed a project ,where a popup appears upon clicking a button, but the problem is that the popup doesn't appear in the center. How can I solve this issue using CSS?

My HTML,CSS and JS code:`

<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <title>SabzLearn | Js | 165</title>

  </head>
  <body>
    <section>
      <div >
        <h1>click the button below !</h1>
        <button type="button">Click Here</button>
      </div>

try it :

.modal{
  background: white;
  width: 70%;
  padding: 30px;
  border-radius: 6px;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  font-size: 22px;
  font-family: arial;
  position: relative;
}

I would use flexbox:

.modal-parent {
  display: flex;
  align-items: center;
  justify-content: center;
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: rgba(0, 0, 0, 0.6); /* Semi-transparent overlay */
}

.modal {
  background: #fff;
  width: 80%;
  max-width: 600px;
  padding: 20px;
  border-radius: 10px;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.3);
  text-align: center;
  position: relative;
}

.X {
  position: absolute;
  top: 10px;
  right: 10px;
  cursor: pointer;
}
