How do I add line-height to a <select> using jQuery?

Question

I have a element

<select name="dropdown" id="dropdown">
    <option>Option 1</option>
    <option>Option 2</option>
    <option>Option 3</option>
    <option>Option 4</option>
</select>

Now if I add a CSS line-height property to the dropdown, it doesn't work. How would I use jQuery to style this? I prefer not to use plugins, because this is the only styling I wish to apply.

Answer 1

$("#dropdown").css("line-height", value)

why do you need to apply a line-height to the dropdown btw?
