CSS Mobile Width-based Query

[webfoo]

Hello,

I have "master.css" as follows:

@import url("folder/file.css");
@import url("file2.css");
@import url("jquery-ui.css");
@import url("anotherfile.css");
@import url("file5.css");
@media screen and (max-width : 640px) {
@import url("mobile.css");
}

So theoretically, mobile.css should be applied if the user's screen width is small. But no matter what device I use, I can never get the browser to activate mobile.css. If I remove the @media query, mobile.css is imported properly and works. What am I doing wrong?

HI,

Your syntax is invalid as @import should precede all rule sets in a style sheet. The correct way to import with a media query is as follows:

@import url(mobile.css) screen and (max-width:640px);

Thank you! I had never really worked with @import or max-width before in this type of context.
