Prevent Address-Bar hiding in mobile Browsers

Prevent Address-Bar hiding in mobile Browsers

I’m currently working on a website with a horizontal layout. All elements are position:absolute with javascript. Their size is calculated with window.innerHeight. My Problem is that despite the elements are no higher than the window’s height, I can scroll down (height of the addressbar). This is annoying in two ways. First it triggers the window-resize event which I neither want nor need at that time. And Second it does not play well with some content boxes whose content should be scrollable vertically. Sometime I can scroll the boxes, but sometimes the whole page is scrolled first (as said before: height of the addressbar). Is there any solution which would allow me to prevent this address-bar auto-hiding mechanism on all devices.
Thank in advance!
This is not scrollable at all:http://maxeffenberger.de/test.html
This can be scrolled horizontally (makes sense to see hidden content) BUT also vertically until the addressbar is hidden (makes no sense, as there is no additional “vertical” content that would need more space: http://maxeffenberger.de/test2.html

Solution 1:

This is the way I have achieved it:

html {
  background-color: red;
  overflow: hidden;
  width: 100%;
}

body {
  height: 100%;
  position: fixed;
  /* prevent overscroll bounce*/
  background-color: lightgreen;
  overflow-y: scroll;
  -webkit-overflow-scrolling: touch;
  /* iOS velocity scrolling */
  width: 50%;
  margin-left: 25%;
}

Solution 2:

Use this style code on your page.Now your chrome url bar will not hide.It’ll stop scrolling.

<style type="text/css">
  html, body {margin: 0; height: 100%; overflow: hidden}
</style>

Solution 3:

The most reliable solution may be to use the fullscreen API: http://updates.html5rocks.com/2011/10/Let-Your-Content-Do-the-Talking-Fullscreen-API

Solution 4:

if someone still has this problem with the hiding address bar, this is how its worked for me.

 html, body {
    height: 100%;
 }

 body {
    position: fixed;
    margin: 0;
    padding: 0;
    border: 0;
    outline: 0;
    background: 0 0;
        -webkit-overflow-scrolling: touch;
    overflow-x: auto;
    overflow-y: scroll;
 }

 .background {
    position: fixed;
    background-image: url('...');
    background-repeat: no-repeat;
    background-size: cover;
    background-attachment: fixed;
    height: 100%;
    width: 100%;
    margin: 0;
    overflow: hidden;
 }

I try a lot of similar code, but android chrome was killing me. Only this worked for me. When you have navigation at the bottom of the page it’s major problem with that auto-hide bar.

Solution 5:

Use window.innerHeight to set boundaries for your site

You can set html and body or your wrapper to

var height = Math.max(document.documentElement.clientWidth, window.innerWidth || 0);    

Keep in mind, that it needs to be updated on every resize!

window.innerHeight allows you to get the actual height of the inner part of the browser view (no browser bar).
You can achieve the height of the content when the bar is visible, or even when it is hidden (swiped down).

In my case:
1. set body to 100vh via CSS.
Unfortunately vh ignores the browser bars, what causes some trouble on mobile devices with modern browsers that hide the bar while/after scrolling.
Have a look at.

This is also my solution to problems like those above.

2. Calculate the exact height via JS with the stated function. Update on every resize!
=> the content of the site is now restricted to the inner part of the view.

On mobile:
Android 7.1.1/ Chrome 61.0
iOS 9.3.5/ Safari

=> now the browser bar is no longer hiding on scroll- and swipe-events.

Keep in mind:
It is only working, when you do not use some library that leads to believe you are scrolling horizontal, but actually is using body.height.

Solution 6:

With a javascript window.scrollTo(0, 1); you can fix the problem.
