在IOS Chrome上,正文会在没有内容的新标签页或页面上溢出,但是如果重新加载页面,则此问题已解决。对于位于底部的任何元素(绝对或固定)都会造成问题。这是重现该问题的代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,minimum-scale=1, maximum-scale=2, initial-scale=1">
<meta name="apple-mobile-web-app-capable" content="yes">
<style>* {
box-sizing: border-box;
}
html{
height:100%;
}
body {
height:100%;
background-color:yellow;
margin:0 0;
border: 30px solid red;
}
</style>
</head>
<body></body>
</html>
边框应在视口周围显示,但应隐藏在底部导航栏的后面。这是上面代码的结果:
我尝试过的事情(没有一个起作用):
I have tried for a week to find a workaround but to no avail. Any help would be greatly appreciated
Edit: My issue is different from HTML body not filling complete width on mobile devices as I don't have an issue with filling the body, I have an overflowing body issue and mobile chrome behaving differently on a new page as opposed to an existing page. The workarounds on the page didn't work for my issue
My question is the following: Can somebody find a way using css or JS for the HTML body to not overflow when a new page is opened using the code above?
I've reproduced your problem and might have found a solution. I've found this which I think causes your problem:
[...] The core issue is that mobile browsers (I’m looking at you, Chrome and Safari) have a “helpful” feature where the address bar is sometimes visible and sometimes hidden, changing the visible size of the viewport. Rather than adjusting the height of 100vh to be the visible portion of the screen as the viewport height changes, these browsers instead have 100vh set to the height of the browser with address the address bar hidden. The result is that the bottom portion of the screen will be cut off when the address bar is visible, thus defeating the purpose of 100vh to begin with.
The article suggests that
One way to get around this issue is to rely on javascript instead of css. When the page loads, setting the height to window.innerHeight will correctly set the height to the visible portion of the window. If the address bar is visible, then window.innerHeight will be the height of the full screen. If the address bar is hidden, then window.innerHeight will be the height of just the visible portion of the screen, as you’d expect.
他们在评论中建议将内部高度存储在CSS变量中,在每次事件resize
或orientationchange
触发事件时刷新内部高度,并将其应用于html和body标签。在我的测试中,仅部分起作用。从链接访问页面的target="_blank"
效果很好,但是刷新或直接访问页面将显示您通过链接访问页面时描述的问题。为了解决这个问题,我还在load
活动期间更新了变量。在我的iPhone 6s和最新的Chrome应用上,通过链接或直接访问页面似乎现在可以正常工作。我希望这是您要寻找的:
