To make retina img by reducing px size

Codecamp’s instruction :Set the width and height of the img tag to half of their original values. In this case, both the original height and the original width are 200px.

my code:

img { height: 100px; width: 100px;}

freeCodeCamp sticker that says 'Because CamperBot Cares'

What’s wrong with me?

I’m not quite sure what your issue is - the line of code you provided img { height: 100px; width: 100px;} worked for the tests when I checked it.

Try to redo the challenge after reloading the page, sometimes it happens. If not skip the topic for the time being because the code is fine.
