I would like to apply a css file after choosing an option from a html <select> tag.
I tried to use these links to existing css files.
<link rel="stylesheet" href="first.css" />
<link rel="stylesheet" href="second.css" />
How can I use them in <select>?
    <select name="choose-an-option">
        <option value="first">
                            <!--use first.css here-->
        </option>
        <option value="second">
                            <!--use second.css here-->
        </option>
    </select>
