Removing rounded corners from a <select> element in Chrome/Webkit

The user-agent stylesheet for Chrome gives a border-radius of 5px to all the corners of a <select> element. I've tried getting rid of this by applying a radius of 0px through my external stylesheet, as well inline on the element itself; I've tried both border-radius:0px and -webkit-border-radius:0px; and I've tried the even more specific border-top-left-radius:0px (along with it's -webkit equivalent).

None are working.

When I examine the element in webkit's developer tools, the Computed Style still lists the radius as 5px. But if I click the expander arrow next to it to see the specifics, it reads: element.style - 0px. And below that it shows the external css specification I gave of 0px, along with the user-agent stylesheet specification of 5px. And both of those latter two are crossed out, as they should be.

Any ideas?

This works for me (styles the first appearance not the dropdown list):

select {
  -webkit-appearance: none;
  -webkit-border-radius: 0px;
}

Just my solution with dropdown image (inline svg)

select.form-control {
    -webkit-appearance: none;
    -webkit-border-radius: 0px;
    background-image: url("data:image/svg+xml;utf8,<svg version='1.1' xmlns='http://www.w3.org/2000/svg' xmlns:xlink='http://www.w3.org/1999/xlink' width='24' height='24' viewBox='0 0 24 24'><path fill='%23444' d='M7.406 7.828l4.594 4.594 4.594-4.594 1.406 1.406-6 6-6-6z'></path></svg>");
    background-position: 100% 50%;
    background-repeat: no-repeat;
}

I'm using bootstrap that's why I used select.form-control
You can use select{ or select.your-custom-class{ instead.
