Does overflow:hidden applied to <body> work

问题:

Does overflow:hidden applied to <body> work on iPhone Safari? It seems not. I can't create a wrapper on the whole website to achieve that...

Do you know the solution?

Example: I have a long page, and simply I want to hide the content that goes underneath the "fold", and it should work on iPhone/iPad.

回答1:

I had a similar issue and found that applying overflow: hidden; to both html and body solved my problem.

html,
body {
    overflow: hidden;
} 

For iOS 9, you may need to use this instead: (Thanks chaenu!)

html,
body {
    overflow: hidden;
    position: relative;
    height: 100%;
}


回答2:

body {
  position:relative; // that's it
  overflow:hidden;
}


回答3:

Some solutions listed here had some strange glitches when stretching the elastic scrolling. To fix that I used:

body.lock-position {
  height: 100%;
  overflow: hidden;
  width: 100%;
  position: fixed;
}

Had this issue today on iOS 8 & 9 and it seems that we now need to add height: 100%;

So add

html,
body {
  position: relative;
  height: 100%;
  overflow: hidden;
}

Combining the answers and comments here and this similar question here worked for me.

So posting as a whole answer.

Here's how you need to put a wrapper div around your site content, just inside the <body> tag.

 <!DOCTYPE HTML>
 <html>
 <head>
     <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
     <!-- other meta and head stuff here -->
 <head>
 <body>
     <div class="wrapper">
         <!-- Your site content here -->
     </div>
 </body>
 </html>

Create the wrapper class as below.

.wrapper{
    position:relative; //that's it
    overflow:hidden;
}

I also got the idea from this answer here.

And this answer here also has got some food for thought. Something that probably will work equally good in both desktops and devices.

For me this:

height: 100%; 
overflow: hidden; 
width: 100%; 
position: fixed;

Wasn't enough, i't didn't work on iOS on Safari. I also had to add:

top: 0;
left: 0;
right: 0;
bottom: 0;

To make it work good. Works fine now :)



回答7:

Its working in Safari browser.

html,
body {
  overflow: hidden;
  position: fixed
}


回答8:

Why not wrap the content you don't want shown in an element with a class and set that class to display:none in a stylesheet meant only for the iphone and other handheld devices?

<!--[if !IE]>-->
<link media="only screen and (max-device-width: 480px)" href="small-device.css" type= "text/css" rel="stylesheet">
<!--<![endif]-->


回答9:

html {
  position:relative;
  top:0px;
  left:0px;
  overflow:auto;
  height:auto
}

add this as default to your css

.class-on-html{
  position:fixed;
  top:0px;
  left:0px;
  overflow:hidden;
  height:100%;
}

toggleClass this class to to cut page

when you turn off this class first line will call scrolling bar back



回答10:

I've worked with <body>and <div class="wrapper">

When popup opens ...

<body> gets a height of 100% and an overflow:hidden

<div class="wrapper"> gets position:relative;overflow:hidden;height:100%;

I use JS/jQuery to get the actual scrollposition of the page and store the value as data-attribut to body

Then i scroll to the scrollposition in the .wrapper DIV (not in window)

Here is my solution:

JS/jQuery:

// when popup opens

$('body').attr( 'data-pos', $(window).scrollTop()); // get actual scrollpos
$('body').addClass('locked'); // add class to body
$('.wrapper').scrollTop( $('body').attr( 'data-pos' ) ); // let wrapper scroll to scrollpos

// when popup close

$("body").removeClass('locked');
$( window ).scrollTop( $('body').attr( 'data-pos' ));

CSS:

body.locked {position:relative;overflow:hidden;height:100%;}
body.locked .wrapper {position:relative;overflow:hidden;height:100%;}

It works well on both sides ... desktop & mobile (iOS).

Tipps and improvements are welcome :)

Cheers!



回答11:

Yes, this is related to new updates in safari that are breaking your layout now if you use overflow: hidden to take care of clearing divs.



回答12:

It does apply, but it only applies to certain elements within the DOM. for example, it won't work on a table, td, or some other elements, but it will work on a <DIV> tag.
eg:

<body>
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;"/>

Only tested in iOS 4.3.

A minor edit: you may be better off using overflow:scroll so two finger-scrolling does work.



回答13:

Here is what I did: I check the body y position , then make the body fixed and adjust the top to the negative of that position. On reverse, I make the body static and set the scroll to the value I recorded before.

var body_x_position = 0;

function disable_bk_scrl(){

    var elb = document.querySelector('body');

    body_x_position = elb.scrollTop;
    // get scroll position in px

    var body_x_position_m = body_x_position*(-1);
    console.log(body_x_position);

    document.body.style.position = "fixed";

    $('body').css({ top: body_x_position_m });

}

function enable_bk_scrl(){  

    document.body.style.position = "static";

    document.body.scrollTo(0, body_x_position);

    console.log(body_x_position);
}


回答14:

Simply change body height < 300px (height of mobile viewport on landspace is around 300px to 500px)

JS

$( '.offcanvas-toggle' ).on( 'click', function() {
    $( 'body' ).toggleClass( 'offcanvas-expanded' );
});

CSS

.offcanvas-expended { /* this is class added to body on click */
    height: 200px;
}
.offcanvas {
    height: 100%;
}
