以下是代码:
HTML:
<html>
<head>
<title>Sample Title</title>
<link rel="stylesheet" type="text/css" href="style.css"/>
<meta name="viewport" content="width=device-width">
</head>
<body>
<div id="container">
<img id="image" src="http://blog.clove.co.uk/wp-content/uploads/2013/01/Motorola_Razr_HD_Cam_Sample%20(7).jpg">
<img id="arrow_left" src="http://iconizer.net/files/WPZOOM_Developer_Icon_Set/orig/arrow-left.png">
<img id="arrow_right" src="http://iconizer.net/files/WPZOOM_Developer_Icon_Set/orig/arrow-right.png">
</div>
</body>
</html>
CSS:
#container {
position: fixed;
margin: auto;
top: 0;
left: 0;
right: 0;
bottom: 0;
width: 90%;
height: 90%;
background-color: silver;
text-align: center;
}
#image {
position: relative;
top: 50%;
transform: translateY(-50%);
max-width: 100%;
max-height: 100%;
}
#arrow_left {
width: 50px;
position: absolute;
top: 50%;
transform: translateY(-50%);
left: 0;
z-index: 1000;
}
#arrow_right {
width: 50px;
position: absolute;
top: 50%;
transform: translateY(-50%);
right: 0;
z-index: 1000;
}
我要做的是将箭头图像浮动到图像的左侧和右侧,图像的中间位置。我不希望箭头在图像之外。
您会注意到,如果您将此布局调整为横向,则图像与左侧和右侧容器的外边框之间会有间隙。箭头浮动在图像之外。我需要阻止这种情况发生。

如果可以接受,可以通过添加一点jQuery来实现:)
以下是代码:
