将div锁定在屏幕顶部

时间：2016-09-09 21:47:57

标签： html css

我试图将进度条锁定到页面顶部（类：outerDiv_S），因此如果用户向下滚动，他们将始终可以看到他们的进度。

我已经尝试过这篇文章提出的各种解决方案但没有成功：How do you create non scrolling div at the top of an HTML page without two sets of scroll bars

尝试添加

位置：固定;到outerDiv_S 

.outerDiv_S {
    position: fixed;
}

它的作用是将div保护到一个位置，当用户向下滚动页面时它不会移动。

你需要做一些样式来修复div和其他内容的定位。

你需要做的样式将是这样的

.outerDiv_S {
    width: 85%;
    margin: 0px auto;
    text-align: center;
    position: fixed;
    left: 0;
    right: 0;
    top: 0;
    z-index: 9999;
    padding-top: 80px;
    box-sizing: border-box;
    background-color: #000;
}

这是一个你要求的实例

使用首字母缩写；在某些对象上最有可能表现更好： 就像以某种方式，您拥有一个移动网站，并且希望您的框保留在页面顶部。这样一来，它可以更平稳地移动，并且不会跟随页面。

您可能还想使用display：block;可以将菜单设置为禁止放置。有时，除非尝试第二种方法，否则它可能适用于某些主题。

.containter {
display: block;
position: initial;
}

与其他方法不同，有时您可能需要将某些块的所有对象都设置为顶部，也可以使用第一边距功能-28px将其设置为向上28px。如果您的程序块处于绝对值高于所有位置的功能。您可以相应地更改px值和正值。

您的代码块可能位于所有对象之上，但是该对象也没有空间。

您将必须手动找到最高的对象标头并设置：“ padding-top：20px;”相应地，如果块菜单设置为50px，则您希望块设置多少开放空间，然后设置50px。为顶部菜单留出空间。绝对的覆盖条件下的所有其他对象。

.h {
padding-top: 50px; 
}
.containcer {
display: block;
margin: -28px 0 0 0px;
position: absolute;
{
