How can I style text within a `` dropdown option?

In your example, the following CSS can achieve the desired effect:

<code class="css">.grey_color {
  color: #ccc;
  font-size: 14px;
}</code>

However, to apply the styling solely to the first option, target it with inline styling rather than a class:

<code class="html"><select id="select">
  <option style="color: gray" value="null">select one option</option>
  <option value="1" class="others">one</option>
  <option value="2" class="others">two</option>
</select></code>

Note, CSS is cascaded. Therefore, define a class for any subsequent options that inherit styling but specify differing attributes, such as color. This approach ensures both readability and maintainability within your codebase:

<code class="css">.others {
  color: black;
}</code>
