As shown in the image attached, there is a very large gap between each of my elements and I was to reduce that vertical gap. This is my code so far, but I'm not sure what to add to the CSS to fix the issue. Thanks

  <div className="flex-container">
    <Email username={username}/>
    <Message username={username}/>
    <Whatsapp username={username}/>
  </div>
 .flex-container {
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  height: 700px;
  display: block; /* Make the buttons appear below each other */
}
