This is probably not related but I assigned some fonts to input place holders. One of my input types is <select> and one of the options within <select> is my default option. I would like to assign same rule to that as my placeholders have.
Mileage will vary greatly between browsers and some will apply all the styles and some may not apply them so you need to check in case you end up with white text on a white background but you can do something like this.
On a quick check it looks as though IE11, Edge, Chrome and Firefox on windows will apply those styles. On a mac system Chrome and Safari will not apply any styles to options but Firefox will.
