Question

I have a list such like below, in Firefox the images actually scale along with the browser width, but in Chrome when I resize the images stay the same size and the <li> sections just fill with white space. See what I mean here

html

<ul>

Answer 1

@-moz-document url-prefix() {  
    li img{
        width: 100%;
        max-width: 100%;
    }
}

@media screen and (-webkit-min-device-pixel-ratio:0) {    
    li img{
        max-width: 100%;
    }    
}

turns out I needed to add max-width add gave in to conditional browser hacking for firefox and chrome
