前端 - @media screen and (min-width:800px)

Question

@media screen and (min-width:800px){ 
    .a{ 
        background: url('../image/banner/banner1.jpg') no-repeat left top;
    }
}

当在移动设备之类的窗口＜800px的时候打开页面，这时候浏览器会不会去下载a类的背景图片吗？

Answer 1

No. You can answer this kind of question by practicing it yourself, so why bother asking

Answer 2

Of course not
