Grab and resize.

Hi, if i grab my browser from a wide screen to a smaller one, my web site don't scale, seems like the media query didn't works properly, but, if I use chrome extension and other development tool for screen size test, my media query works!

How i can solve this problem?

ps: Are there even English courses in treehouse? ;)

So it sounds like it is only working when the screen refreshes. Can you post your CSS code or possibly share the code through a workspace so we can test it?

Even if i refresh the page nothing change. CSS:

'''@media screen and (max-width : 320px){ .grid_1, .grid_2, .grid_3, .grid_4, .grid_5, .grid_6, .grid_7, .grid_8, .grid_9, .grid_10, .grid_11, .grid_12 { width: 100%; }

ul.nav{ 
    float: none;
}

li{
    display: table;
    text-align: center;
}

}'''

HTML '''<body> <div class="container clearfix">

    <div class="grid_2">
            <h1>01 / 01</h1>
    </div>

            <div class="10 omega">
        <div id="?">
            <h3>?</h3>
            <img src="img/mywork/my.jpg">
        </div>
    </div>

    <div class="grid_2">
        <div class="full_scale_height">
            <ul class="nav">
                <li><p><a href="#?">?</a></p></li>
                <li><a href="#censured">censured</a></li>
            </ul>
        </div>
    </div>....'''

It looks like the rule doesn't kick in until your screen size is 320px or less since you set the max-width to that size. Unless you have a width set to a percentage for your global css then you wouldn't see the screen change at all until you get your browser size down to 320px.
