Transition duration working but not validated by WS's

Again WS's is not validating the code. It's actually working in the preview.

style.css
/* Complete the challenge by writing CSS below */

.content {
  transition-property: background, color;
  transition-duration: .005s, .004s;
}

.invert:checked ~ .content {
    color: #fff;
    background: #373737;

There are 1000 milliseconds in a second. So, 500ms is equal to .5s and 400ms is equal to .4s

Ah yes I see my simple confusion. I was setting to 5 milliseconds instead of 500. lol
