JavaScript中的窗口宽度

Question

I have some mystic troubles with $(window).width() .

I open my site in Chrome Device Toolbar with 320xXXX window size. Then, I run in Google Chrome JavaScript console $(window).width() and it says 980 . And that's why none of my @media in css not working. Is there is any explanation for that?

By the way, when I resize Chrome window, it magicaly start to see correct window width.

As OP's comment, here is the answer.

You will need to add viewport tag to archive @media css

<meta name="viewport" content="width=device-width, initial-scale=1">
