How can I use the CSS pseudo-element :before{ content: ” } to affect an element?

by

The ::before and ::after pseudo-elements actually prepend/append a child node to the element, so this will not work on any element that cannot contain child nodes.

It would be (roughly) the equivalent of doing:

<option><span>sandy - </span>beach</option>

If you want to update the text value, you will need to use JavaScript.
