How to change text size on category pages

You can change admin css with this code to functions.php:

add_action('admin_head', 'my_custom_fonts');

function my_custom_fonts() {
  echo '<style>
    body.taxonomy-category .row-title,body.taxonomy-category input{
      font-family: "Lucida Grande";
      font-size: 16px;
      color: #f04040;

  </style>';
}
