Tips on updating the initial value of a select box or placeholder?

Here is a select input:

<select name="" id="">
 <option disabled hidden selected value="">
  default
 </option>
 <option value="2">2</option>
 <option value="3">3</option>
 <option value="3">3</option>
</select>

I want to style the placeholder or first value differently to make it appear like a placeholder. I have attempted various CSS rules like:

select option:disabled { color: red; }
select :invalid { color: red; }
select option:first-child { color: red; }
select { color: grey; } option:first-child { color: red;}

Unfortunately, none of these approaches have been successful, leaving me unsure of how to proceed. I would prefer not to resort to transparent text color and overlaying a label on the select input.

Answer №1

When referencing this particular answer, keep in mind that styling it may not be possible as it is generated by the operating system.

However, in this specific scenario, you have the option to include the disabled attribute with the placeholder value. This will display the value in a greyed-out state in the list, making it unselectable. This action will prevent users from submitting the form with an invalid placeholder value!

You can witness this functionality in action by visiting this fiddle for testing purposes (while also observing that various rules are applied to the option element without success).
