When I pull it up, the app is allowing vertical scroll when it shouldn't be. I've gone through the same process with other web apps without any issues, and am not sure what I am missing this time around.

Trying to debug this issue in weinre and discovered that the document width and height are somehow equal, when height show be much smaller in landscape. Searching around SO, other answers have been to supply a viewport meta tag, which I'm already doing. Can someone point me to a solution here? It looks to me like you are using too many properties of viewport that might conflict with each other.

Apple suggests to set few of them or one and test in isolation as others are automatically inferred.

Bootstrap in its basic template recommends to set only width and initial-scale. I would be very careful with maximum-scale or anything restricting user's zooming as it forces the user into uncomfortably small or large text. Not sure why since I literally just copy and pasted this tag from another app that worked just fine.

I think that might do what you want. Best practice for mobile websites is not to hide things, but to reformat the content into a longer narrower column. Websites that hide content are unfortunately common, but they won't make users happy. Just for the sake of someone who comes along later, it appears that iOS safari just spoofs the user agent when requesting "Desktop Site".

I tried several other apps that advertise that they can do this, but Desktop Browser is the only one that worked on the AWS Console page.Safari on iOS displays webpages at a scale that works for most web content originally designed for the desktop.

You especially need to configure the viewport if you are designing webpages specifically for iOS. Configuring the viewport is easy—just add one line of HTML to your webpage—but understanding how viewport properties affect the presentation of your webpages on iOS is more complex.

Before configuring the viewport, you need a deeper understanding of what the visible area and viewport are on iOS. If you are already familiar with the viewport on iOS, read Using the Viewport Meta Tag for details on the viewport tag and Viewport Settings for Web Applications for web application tips. Otherwise, read the sections in this chapter in the following order:. Read Safari on iOS Viewport to learn about the available screen space for webpages on small devices.

Read What Is the Viewport? See Supported Meta Tags for a complete description of the viewport meta tag. Safari on iOS has no windows, scroll bars, or resize buttons as shown on the right in Figure The user pans by flicking a finger.

The user zooms in by double-tapping and pinch opening, and zooms out by pinch closing—gestures that are not available for Safari on the desktop. Because of the differences in the way users interact with web content, the viewport on the desktop and on iOS are not the same.

The viewport on the desktop is the visible area of the webpage as shown in Figure The user resizes the viewport by resizing the window. If the webpage is larger than the viewport, then the user scrolls to see more of the webpage. If the webpage is smaller than the viewport, it is filled with white space to fit the size of the viewport. For Safari on iOS, the viewport is the area that determines how content is laid out and where text wraps on the webpage.

The viewport can be larger or smaller than the visible area. When the user pans a webpage on iOS, gray bars appear on the right and bottom sides of the screen as visual feedback to show the user the size of the visible area as compared to the viewport similar to the length of scroll bars on the desktop.

Using the double tap, pinch open, and pinch close gestures, users can change the scale of the viewport but not the size. The only exception is when the user changes from portrait to landscape orientation—under certain circumstances, Safari on iOS may adjust the viewport width and height, and consequently, change the webpage layout.

For example, the webpage on the right in Figure appears too narrow. Because Safari on iOS provides a viewport, you can change the default settings.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. You are right. There is no default viewport height, as such.

I could not quite understand the question. But yes, since the iPad resolution is xpx, So in landscape mode, the height should be around px minus the address bar height which should be around 40px or so.

The way most browsers work is they allow to set the width and height is adjusted accordingly based on other factors including initial zoom level as well. So you need to work with setting width most of the times. How are we doing? Please help us improve Stack Overflow. Take our short survey.

The iOS Safari menu bar is hostile to web apps: discuss

Ask Question. Asked 3 years, 11 months ago.Learn Development at Frontend Masters. Viewport units have always been controversial and some of that is because of how mobile browsers have made things more complicated by having their own opinions about how to implement them. Case in point: should the scrollbar be taken into account for the vw unit? Then there are physical attributes of the devices themselves hello, notch! The spec is pretty vague about how viewport units should be calculated.

So yeah, no clear guidance there when it comes to handling device and browser-specific differentiations.

Once you get past a piece of the browser interface, like the address bar, the vh value would update and the result was an awkward jump in the content. Safari for iOS was one of the first mobile browsers to update their implementation by choosing to define a fixed value for the vh based on the maximum height of the screen. By doing so, the user would not experience jumps on the page once the address bar went out of view. As of this writing, there is a ticket to address this in Firefox Android.

While using a fixed value is nice, it also means that you cannot have a full-height element if the address bar is in view. The bottom of your element will be cropped. The idea struck me that CSS Custom Properties and a few lines of JavaScript might be the perfect way to get the consistent and correct sizing I needed.

In JavaScript, you can always get the value of the current viewport by using the global variable window. The trick is to store the viewport value in a CSS variable and apply that to the element instead of the vh unit. That means we will want to apply it in our CSS like this:. As a result, we can now use --vh as our height value like we would any other vh unit, multiply it by and we have the full height we want.

Go ahead and try resizing the demo above. We can update the value of --vh by listening to the window resize event. This is handy in case the user rotates the device screen, like from landscape to portrait, or the navigation moves out of view on scroll.

For example, this comes up a lot with ::focus. Frontend Masters is the best place to get it. Thank you very much will try this to fix my website soon. Could you elaborate your use case? You need an in-flow full-height element at the top of the page? Apparently, some users will assume that there is no content below. But the concept is the same.

Add a. This is not really mentioned in the article but CSS Custom Properties can have fallback if the property is not defined.

This gets rid of the default behaviour. To me it looks like the issue you are having is caused by it.My loathing of Safari on iOS is largely restricted to the menu bar. The kind of layouts popularised by iOS itself:. Fancy a game of wack-a-mole? Every time Safari registers a touch in this area it pops up the Safari menu bar and you have to click what you clicked again. Safari on iOS considers the bottom 44px of the viewport sacrosanct in general. Plain old links that are unfortunate enough to be scrolled into that area have to be tapped twice too.

Back in iOS7 we had the minimal-ui meta tag. That is to say, on iOS7 with minimal-ui present, the page loaded with a minimal amount of browser chrome by default. Users got the menu bar back by clicking the header chrome. Apple subsequently removed minimal-ui as a thing. I can appreciate that move; having no obvious back button on some pages and not others could be bad for users. However, there are more problems with the current iOS Safari menu bar beside usability. From a technical perspective, here are a few:.

I made a litle test page to demonstrate some of this. Load it up in Safari and scroll to see the difference, and the difference again when you save to home screen and then run it from there. In addition, take a look at another demo my colleague, Tom Millard, made. I implore you, if you have any strong feeling, data, anecdotal evidence on this pattern being a problem, please comment below. It regularly causes problems with widgets like live chat that are docked to the bottom of the screen.

Imagine a stacked page with 4 items of 25vh height each. When the menu bar shows and hides, the whole page reflows. It seems as if we would need to rely on good old javascript and binding to window resize to get the accurate height at all times. Scroll down the page a little so the iOS chrome withdraws and the try and click one of the Quartz menu bar items; see how the iOS menu bar reappears? Ben, I agree, this has been a huge pain in the behind! I have spent so much effort optimizing my app for the mobile web, making sure it is nearly as good as the native experience, so that it is accessible to people in the easiest way possible — a plain hyperlink!

But this bottom bar is a fiasco. I am probably going to just make the bottom 44px a dead zone in the app — and fill it with nothing but the background. It is a huge detriment to the functionality of the web app on Safari. I hope it is not intentional by Apple, that would be short-sighted, since I still want to drive installs to my mobile app, the web site is just a lite version! No js browser detection needed as it causes no quirks in iOS Chrome, Safari fullscreen, or on Android browsers.

How have they done it? Appreciate any pointers. Have the same experience. How can one browser feel free to disrupt the behavior on a website.

I completely agree that the 44px no-fingers-land at the bottom of the viewport should go and stop messing around with the actual content of the page. However, I think the current behavior for the vh unit is the least annoying one. As of today, the only reliable way to get these dimensions is to calculate the difference between two window.

I cannot tell you how much time I have now spent trying to get a sticky footer with a button inside it that does not require to be clicked twice before it works. I still have no real solution.
