注意空网格区域!

在我的例子中，我有这样的东西:

.cart-areas {
    grid-template-columns: 2fr 0.2fr 1.5fr;
    grid-template-areas:
      'order . summary'
      'order . .'
      'order . .';
}

我希望当用户完成结帐表单时，总结网格项具有粘性。它没有工作，因为那些空的网格项(用。标记)。

解决方案是删除这些空项，如下所示:

.cart-areas {
    grid-template-columns: 2fr 0.2fr 1.5fr;
    grid-template-areas:
      'order . summary'
      'order . summary'
      'order . summary';
}

这里有两个答案:

从正文标签中移除溢出属性 设定高度:100%到机身以解决溢出问题y:自动

Min-height: 100%不工作，而不是高度:100%

我还遇到了一些事情:

当你的sticky元素是一个组件时(angular等)

如果“sticky”元素本身是一个带有自定义元素选择器的组件，比如一个名为<app-menu-bar>的angular组件，你需要在该组件的css中添加以下内容: :主机{显示:块;} //或使用flexbox

or

    app-menu-bar  { display: block; }   // (in the containing component's css)

Safari on iOS in particular seems to require `display:block` even on the root element `app-root` of an angular application or it won't stick.

If you are creating a component and defining the css inside the component (shadow DOM / encapsulated styles), make sure the position: sticky is being applied to the 'outer' selector (eg. app-menu-bar in devtools should show the sticky position) and not a top level div within the component. With Angular, this can be achieved with the :host selector in the css for your component. :host { position: sticky; display: block; // this is the same as shown above top: 0; background: red; }

其他

If the element following your sticky element has a solid background, you must add the following to stop it from sliding underneath: .sticky-element { z-index: 100; } .parent-of-sticky-element { position: relative; } Your sticky element must be before your content if using top and after it if using bottom. There are complications when using overflow: hidden on your wrapper element – in general it will kill the sticky element inside. Better explained in this question Mobile browsers may disable sticky/fixed positioned items when the onscreen keyboard is visible. I'm not sure of the exact rules (does anybody ever know) but when the keyboard is visible you're looking at a sort of 'window' into the window and you won't easily be able to get things to stick to the actual visible top of the screen. Make sure you have: position: sticky; and not display: sticky;

杂项可用性问题

Be cautious if your design calls for for sticking things to the bottom of the screen on mobile devices. On iPhone X for instance they display a narrow line to indicate the swipe region (to get back to the homepage) - and elements inside this region aren't clickable. So if you stick something there be sure to test on iPhone X that users can activate it. A big 'Buy Now' button is no good if people can't click it! If you're advertising on Facebook the webpage is displayed in a 'webview' control within Facebook's mobile apps. Especially when displaying video (where your content begins in the bottom half of the screen only) - they often completely mess up sticky elements by putting your page within a scrollable viewport that actually allows your sticky elements to disappear off the top of the page. Be sure to test in the context of an actual ad and not just in the phone's browser or even Facebook's browser which can all behave differently.

我也有同样的问题。对我来说，问题在于大屏幕上的显示:“none”(media-query)和智能手机上的显示:“initial”。如果我删除了display css属性，并在桌面上添加了不透明度和指针事件，一切都解决了。

粘性定位是相对定位和固定定位的混合体。元素被视为相对定位，直到它超过指定的阈值，此时它被视为固定定位。 .．. 您必须指定一个阈值，其中至少有一个是上、右、下或左，以便粘滞定位按预期的方式工作。否则，它将与相对定位难以区分。 (来源:中数)

在你的例子中，你必须通过使用top属性来定义它最后应该停留的位置。

html, body { height: 200%; } nav { position: sticky; position: -webkit-sticky; top: 0; /* required */ } .nav-selections { text-transform: uppercase; letter-spacing: 5px; font: 18px "lato", sans-serif; display: inline-block; text-decoration: none; color: white; padding: 18px; float: right; margin-left: 50px; transition: 1.5s; } .nav-selections:hover { transition: 1.5s; color: black; } ul { background-color: #B79b58; overflow: auto; } li { list-style-type: none; } <nav> <ul align="left"> <li><a href="#/contact" class="nav-selections" style="margin-right:35px;">Contact</a></li> <li><a href="#/about" class="nav-selections">About</a></li> <li><a href="#/products" class="nav-selections">Products</a></li> <li><a href="#" class="nav-selections">Home</a></li> </ul> </nav>

我也有同样的问题，我在这里找到了答案。

如果你的元素没有像预期的那样粘在一起，首先要检查应用到容器上的规则。

具体来说，查找元素的任何父元素上设置的溢出属性。不能在position: sticky元素的父元素上使用:overflow: hidden、overflow: scroll或overflow: auto。
