不管内容如何。

有可能做到吗?

这是最稳定(和简单)的方法,在所有现代浏览器中都适用:

.fullscreen { position: fixed; top: 0; left: 0; bottom: 0; right: 0; overflow: auto; background: lime; /* Just to visualize the extent */ } <div class="fullscreen"> Suspendisse aliquam in ante a ornare. Pellentesque quis sapien sit amet dolor euismod congue. Donec non semper arcu. Sed tortor ante, cursus in dui vitae, interdum vestibulum massa. Suspendisse aliquam in ante a ornare. Pellentesque quis sapien sit amet dolor euismod congue. Donec non semper arcu. Sed tortor ante, cursus in dui vitae, interdum vestibulum massa. Suspendisse aliquam in ante a ornare. Pellentesque quis sapien sit amet dolor euismod congue. Donec non semper arcu. Sed tortor ante, cursus in dui vitae, interdum vestibulum massa. Suspendisse aliquam in ante a ornare. Pellentesque quis sapien sit amet dolor euismod congue. Donec non semper arcu. Sed tortor ante, cursus in dui vitae, interdum vestibulum massa. </div>

测试工作在Firefox, Chrome, Opera, Vivaldi, IE7+(基于在IE11的仿真)。

嘿,这招对我很管用

# splashScreen { 背景颜色:白色; 位置:绝对的; 上图:0 px; 左:0 px; 宽度:100%; 高度:100%; 溢出:汽车; max-width: 2000 px; }

这对我来说总是有效的:

<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <style type="text/css">
        html, body {
            height: 100%;
            margin: 0;
        }

        #wrapper {
            min-height: 100%; 
        }
    </style>
    <!--[if lte IE 6]>
    <style type="text/css">
        #container {
            height: 100%;
        }
    </style>
    <![endif]-->
</head>

<body>
    <div id="wrapper">some content</div>
</body>

这可能是这个问题最简单的解决方案。只需要设置四个CSS属性(虽然其中一个只是为了让IE高兴)。

不幸的是,CSS中的height属性并不像它应该的那样可靠。因此,必须使用Javascript来将所讨论元素的height样式设置为用户视口的高度。是的,这可以在没有绝对定位的情况下完成……

<!DOCTYPE html>

<html>
  <head>
    <title>Test by Josh</title>
    <style type="text/css">
      * { padding:0; margin:0; }
      #test { background:#aaa; height:100%; width:100%; }
    </style>
    <script type="text/javascript">
      window.onload = function() {
        var height = getViewportHeight();

        alert("This is what it looks like before the Javascript. Click OK to set the height.");

        if(height > 0)
          document.getElementById("test").style.height = height + "px";
      }

      function getViewportHeight() {
        var h = 0;

        if(self.innerHeight)
          h = window.innerHeight;
        else if(document.documentElement && document.documentElement.clientHeight)
          h = document.documentElement.clientHeight;
        else if(document.body) 
          h = document.body.clientHeight;

        return h;
      }
    </script>
  </head>
  <body>
    <div id="test">
      <h1>Test</h1>
    </div>
  </body>
</html>

使用Fullscreen API和:Fullscreen伪选择器,任何元素都可以切换全屏模式。

注意:

Stackoverflow不允许全屏模式(document.fullscreenEnabled),因此代码段不能在这里演示requestFullscreen()方法。

我认识到这个问题不需要jQuery。我正在使用一个库来简化事件绑定。当然,香草JS也可以代替。

const ns = { img_click: (e) => { if (document.fullscreenElement) { document.exitFullscreen(); console.log('exited fullscreen'); } else { console.log('entering fullscreen'); e.currentTarget.requestFullscreen(); } } }; $('body').on('click', 'img', ns.img_click); console.log('Fullscreen allowed:', document.fullscreenEnabled); .gallery { display: flex; gap: 1em; } img { width: 100px; aspect-ratio: 1/1; border-radius: .5em; cursor: zoom-in; object-fit: cover; } img:fullscreen { width: 100%; aspect-ratio: auto; object-fit: contain; } <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="gallery"> <img src="https://picsum.photos/id/123/500/250" alt="Random image" /> <img src="https://picsum.photos/id/234/250/500" alt="Random image" /> <img src="https://picsum.photos/id/345/500/500" alt="Random image" /> </div>

这应该工作,虽然我没有IE测试。
