Select Menu and Button still visible at screens wider than 568px

In the Perform: Part 3 video, Andrew uses CSS media queries to modify the visibility of the select menu and button at certain screen sizes. Why doesn't the same code work on my machine?

@media (min-width: 568px) {
    #menu select, #menu button {
        display:none;
    }
}

I checked two other similar answers, one had a typo and in another one it was suggested to use select#menu, but that's not really true. The <select> element is a child of the <div> element with ID of 'menu' so #menu select should work. Besides it works in the video anyway.

}

Remove the space before 568px?

I had a similar problem in another course and that seemed to solve it. Although it's not wrong to type a space before the number.

Make sure there are no rules below yours that overwrite the style. This is the cascading part of CSS. In most cases, your media query should come last.

Hi Manish,

Were you able to resolve this issue? I am also facing the same issue and not sure why the media css styling is not working.

EDIT: This change is not working in Google Chrome browser. I launched the preview in Safari and was able to see the code work.

Thanks, Priyesh

I had to split them up

'''css

@media (min-width: 568px) { 

#menu select { display: none; } 

#menu button { display: none; }

}

'''
