title: Resize buttons with window resizing
body: <p>I have made two rows of buttons (with letters A-Z). Css code for buttons and rows is:</p>
  <pre><code>.buttons{
    display: flex;
    background-color: #009999;
    border: none;
    border-radius: 0.3em;
    color: white;
    text-align: center;
    text-decoration: none;
    display: inline-block;
    cursor: pointer;
    
    width: 2em;
    height: 2em;
    font-size: 1.6em;
    padding: 0.2em ;
    margin: 0.1em;
    
    text-align: center;
    font-weight: bold;
   
  } 
  .firstRow, .secondRow {
    display: flex;
    flex-direction:  row;
    align-items: center;
    padding: 0.2rem;
    list-style-type: none;
    width: 90%;
  }
  
  
  </code></pre>
  <p>When I resize the window, I want these buttons to resize according to the size of the window as well.
  My problem is that when I reduce the size of the window, the letters remain the same size and they are not all shown on the screen.</p>
