How to use ONLY the first letter of an HTML element using CSS?

Question

text-transform: capitalize does not work in this case, because the text already has an uppercase.

<select>
    <option>
      OPTION
    </option>
</select>

That didn't work either.

select{
  -webkit-appearance: none;
  text-transform: lowercase;
  display: inline;
}

select option::first-letter{
  text-transform: uppercase;
}

It should work on Chrome (at least) using CSS (not JS).

In Chrome and Firefox, you can create an element optionif it selectis larger than 1.

You can use it as follows:

select {
  height: 1.4em;             /* show only one option when not focused */
}

select:focus {
  height: 100%;              /* show all options when focused */
}

option  {
  text-transform: lowercase; /* change to lowercase */
  padding-right: 2em;        /* the select width is based on width of its longest non-transformed ... */
                             /* option.  padding ensures that option is completely visible */
  display: none;             /* hide all options by default (see below) */
}

option::first-letter {
  text-transform: uppercase; /* change first letter to uppercase */
}

option:checked, select:focus option { 
  display: block;            /* show selected option, or show all options when the select is focused */
}

<select size="4">
  <option selected>NOW IS THE TIME</option>
  <option>for all good men</option>
  <option>tO Come To tHe aid</option>
  <option>of the party</option>
</select>

Run codeHide result

It will not act like a regular selection box, and Chrome has a weird behavior, since the selected option will have a gray background. I can’t figure out how to prevent this.
