溢出滚动css在div中不起作用

Question

应该修复头部，我不想要整体滚动条，所以我在主体标记中给出了overflow：hidden,

我需要垂直滚动条在我的包装div。我怎么才能修好这个？

HTML

<div id="container">

    <div class="header"></div>

    <div class="wrapper">
        <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Vivamus porta tortor sed metus. Nam pretium. Sed tempor. Integer ullamcorper, odio quis porttitor sagittis, nisl erat tincidunt massa, eu eleifend eros nibh sollicitudin est. Nulla dignissim. Mauris sollicitudin, arcu id sagittis placerat, tellus mauris egestas felis, eget interdum mi nibh vel lorem. Aliquam egestas hendrerit massa. Suspendisse sed nunc et lacus feugiat hendrerit. Nam cursus euismod augue. Aenean vehicula nisl eu quam luctus adipiscing. Nunc consequat justo pretium orci. Mauris hendrerit fermentum massa. Aenean consectetuer est ut arcu. Aliquam nisl massa, blandit at, accumsan sed, porta vel, metus. Duis fringilla quam ut eros.</p>
        <!-- Lots more paragraphs-->
    </div>

</div>

body{ margin:0; padding:0; overflow:hidden; height:100%}
#container { width:1000px; margin:0 auto;}
.header { width:1000px; height:30px; background-color:#dadada;}
.wrapper{ width:1000px; overflow:scroll; position:relative;}

Answer 1

您缺少heightCSS属性。

添加它，你会注意到滚动条将出现。

.wrapper{ 
    // width: 1000px;
    width:600px; 
    overflow-y:scroll; 
    position:relative;
    height: 300px;
}
