我有一个关于表的示例和底部的一些控件。我希望这个表控件在屏幕很小时是不可见的，但我不知道它不起作用。谁能帮我？非常感谢！

使用这些代码代替您的代码：
@media only screen and (min-width : 320px) and (max-width : 480px) {
body {
padding: 0;
margin: 0;
width: 320px;
}
#table-control {
display: none !important;
visibility: hidden;
}
}
/* iPads (portrait and landscape) ----------- */
@media only screen and (min-width: 768px) and (max-width: 1024px) {
body {
width: 495px;
}
#table-control{
display: none !important;
visibility: hidden;
}
}

在媒体查询中尝试使用min-width和max-width代替min-device-width和max-device-width。

尝试在HTML中替换此行
<meta name='viewport' content='width=device-width, initial-scale=1.0'>
这一行：
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1" />
我在使用第一个Meta时遇到了一些错误..但是当它被替换时一切都很好
