    option.red {background-color: #cc0000; font-weight: bold; font-size: 12px;}
    option.pink {background-color: #ffcccc;}

    <select name=colors>
    <option class="red" value= "../getting_started/">Getting Started </option>
    <option class="pink" value= "../getting_started/html_intro1.htm">- Intro to HTML
     </option>
    </select>

CSS和HTML

  color: red;
}
#option-2 {
  color: green;
}

#option-3 {
  color: yellow;
}

#option-4 {
  color: blue;
}

<select>
  <option id="option-1">Option 1</option>
  <option id="option-2">Option 2</option>
  <option id="option-3">Option 3</option>
  <option id="option-4">Option 4</option>
</select>

Answer 3

我猜你的意思是select？这应该有效：

option:nth-child(1) { background: green; }
option:nth-child(2) { background: blue; }
