Prevent certain page elements to not be pinch-zoomable on iOS - iphone

I have a basic HTML page with a header that is fixed. When I pinch-zoom in to the page on an iPad or iPhone the header flows off the edge of the page and I can not drag the page to see it all.
I can prevent the whole page from being zoomable, but I would like just this fixed header to not zoom and the rest of the page to be zoomed as normal.
Is there any way to do this?
EDIT:
Here's my CSS/HTML
body {
margin:0;
padding:0;
}
.nozoom {
width:100%;
position:fixed;
top:0px;
margin:0 auto;
}
.nozoom > div {
width:1008px;
margin:0 auto;
background-color:#444;
height:100px;
}
.yeszoom {
width:1008px;
margin:100px auto 0;
background-color:#096;
}
and...
<div class="nozoom"><div>This must not zoom and if you look carefully you'll see that you can never see the content of this which is completely over to the left - one two three four five six seven eight nine ten eleven twelve thirteen... dfgkjhdfsklhj dsfkjghl sdflghsdfklg sdfklg dsfkgh skdlfgh ksdlf ghskdlfgh jklsdfhg jklsdfg hsdfghj sdflkg hlsdf sdfg kljsdf jksdf sdfkjg sdfg ksdjfl gjkldsfg klsdfhgljksdf gsd kjlsdfh glskjdfhg jsdf hsdflk gsdf</div></div>

Gif link to center

Trying to get the "About Us" to no go to a separate page, but instead just go to the center of screen.
<div class="w3-col s4">
<h4>About</h4>
<p>About us</p>
<p>Shipping</p>
<p>Payment</p>
</div>
You need a bit different approach.
The tag defines a hyperlink, which is used to link from one page to another. So, it is a normal behaviour that click brings you to another page. But it is not what you want. To show popup, you can use javascript.
There are different approaches you can use like Bootstrap Modals, jQuery or W3C.CSS Modals. I see, that you use classes from W3C.CSS. You can read about W3C.CSS Modals here.
You can also use a pure JS. Exactly this approach I show here. Basically, the idea is the following. You have a hidden component styled so that it appears in the center of the screen (like a modal). The modal is hidden by default. There is a JS function that makes the modal visible. Clicking your link you triggers this function. Look at the code below.
function showGif() {
document.getElementById('box').classList.remove('hidden');
}
.box {
display: flex; /* defines a flex container */
align-items: center; /* aligns content vertically */
justify-content: center; /* aligns items horizontally */
height: 100vh; /* makes the block fit all the viewport's width */
width: 100vw; /* makes the block fit all the viewport's height */
position: absolute; /* needs to overlay other elements */
}
.hidden {
display: none;
}
<div class="w3-col s4">
<h4>About</h4>
<p>About us</p>
<p>Shipping</p>
<p>Payment</p>
</div>
<div id="box" class="box hidden">
<img src="https://www.linkpicture.com/q/unnamed_10.gif" />
</div>
I didn't implement the functionality of hidding the modal. And CSS is probably not perfect. It is just an example to show you the idea. So, the final implenetaion is up to you. I hope, it will help.

Overflow-x value ignored in mobile safari

We set the overflow-x values to hidden on both the body and scrollable elements, but mobile Safari ignores these values. On the desktop, the overflow values work fine.
Relevant code:
body { overflow-x:hidden; width:320px; height:100%; min-height:100%; margin:0; background:-webkit-linear-gradient(top,#e8e4dc,#f2f0eb); }
.page_list, .content { max-height:370px; box-sizing:border-box; padding:0; overflow-x:hidden; overflow-y:auto; -webkit-overflow-scrolling:touch }
#catalog_page { border-left:1px solid #CCC; z-index:28; position:absolute; top:0; width:200px; height:460px; background:white; -webkit-transition:-webkit-transform 0.1s ease-in;; -webkit-transform:translate3d(0,0,0); display:none; }
catalog_page is what sits outside the viewport, sliding into view only after someone does a gesture.
To reproduce:
1) Visit www.tekiki.com on your iPhone (not iPad). Scroll to the right, and you'll see how catalog_page extends the site's width, even though we fixed the body width.
Add html { overflow: hidden; } to your CSS and it should fix it.
It's 2020 but I am still trying to find an answer for this.
After many experiments, I found that this answer was actually the only working one.
However, it does create an odd black bar across the whole page in all browsers. Also, you should not use units for zero values.
Therefore, my final solution is this: (any transform function should do the trick, just remember to set zero values.)
html, body {
... (font, background, stuff)
overflow-x: hidden;
/* Safari compatibility */
height: 100%;
width: 100%;
transform: translate3d(0,0,0);
}
Be aware, this solution may influence on your navigation.
"position: fixed;" will not work on children because of "transform" property set something other than "none"
https://developer.mozilla.org/en-US/docs/Web/CSS/position#fixed
Tested with Mobile Safari on iOS 7.1/8.2
Following code didn't work for me neither.
html { overflow: hidden; }
I believe it's a bug/feature of Mobile Safari, other browsers, including Safari on OSX works well. But the overflow:hidden works on iPhone/iPad if you also set position:fixed to HTML element. Like this:
html { overflow: hidden; position: fixed; }
Add html { overflow: hidden; } to your CSS and it should fix it.
This solution didn’t work for me.
Instead, i create a wrapper div inside the body and apply the overflow-x:hidden to the wrapper :
CSS
#wrapper {
overflow-x: hidden;
}
html
<html>
...
<body>
<div id="wrapper">
...
</div>
</body>
</html>
I had the following code to disable double-tap to zoom:
* {
touch-action: none;
}
This broke overflow scrolling though. Here’s how I fixed it:
pre {
overflow-x: scroll;
touch-action: pan-x;
}
in my case, the following did solve the problem
body, html {
overflow-x: hidden;
}
I actually gave up on css overflow-x in IOS safari.
I used script instead
$(window).scroll(function ()
{
if ($(document).scrollLeft() != 0)
{
$(document).scrollLeft(0);
}
});
It's 2022. Mobile safari can still be quirky. But it seems for me the way to get overflow-x working on the body is to do the following:
html,
body {
height: 100%;
overflow-x: hidden;
transform: translate3d(0, 0, 0);
}
I wish I understood the transform, but it seems necessary. The other way was to set the body to position of relative, but this seems safer.
OR
Another way thats definitely safe, and future proof, is to place everything in body directly into a div and give that div an overflow of hidden and make sure it has a min-height of 100vh. Like so:
<body>
<div class="page">
everything...
</div>
</body>
Then in CSS:
.page {
min-height: 100vh;
overflow: hidden;
position: relative;
}
In order to solve the issue on older devices (iphone 3) as well I had to mix the solutions, because they didn't work singularly.
I ended up adding a wrapper div to the html body:
<html>
<body>
<div id="wrapper">....</div>
</body>
</html>
and styling it with:
#wrapper {
overflow: hidden
}
and it finally worked.
If html, body overflow-x: hidden; is not working for you try looking for text-indent. The default settings of flexslider for example have some elements set to text-indent -9999px. I found this was overriding html overflow rules.

website for iphone css media queries

I am trying to fit my website for iphone
for that i am using twitter bootstrap responsive css
i gave the container with different border colors for different width
but when i minimize the browser window the border colors are not reflecting for the browser window
http://jsfiddle.net/CXkQp/1/
http://jsfiddle.net/CXkQp/1/embedded/result/
#media (min-width: 1200px) {
.row {
margin-left: -30px;
*zoom: 1;
}
.row:before,
.row:after {
display: table;
line-height: 0;
content: "";
}
.row:after {
clear: both;
}
[class*="span"] {
float: left;
min-height: 1px;
margin-left: 30px;
}
.container,
.navbar-static-top .container,
.navbar-fixed-top .container,
.navbar-fixed-bottom .container {
width: 1170px;
border: 1px solid red;
}
If I understand your question correctly, the page example you posted should be responsive, though I'm not sure that your bootstrap grid is setup the way you need it.
You have nested container divs for one thing # lines 120 and 145
Check what happens if I rename your 2 container divs:
http://jsfiddle.net/panchroma/CXkQp/3/embedded/result/
http://jsfiddle.net/panchroma/CXkQp/3/
line 120
<div class="containerA" style="background-color: white;">
line 145
<div class="containerB">
There are also some validation errors which could possibly be another piece of the puzzle. The cause may be that you can't simply paste HTML head content into the jsFiddle HTML panel as you have done. Check http://doc.jsfiddle.net/use/hacks.html#css-panel-hack for details on what you need to do.
My appologies if I've misunderstood something
Good luck!

Centering divs in HTML and CSS but cut-off on mobile screens

I have been having some real issues with CSS!
I have the following set up to centre the #Box div, which works perfectly on everything but mobile browsers. Because the screen size of the mobile browser is so narrow the left hand side keeps getting cut-off. I asked something similar previously and have tried to no avail to adjust it.
I have put the container and layout divs in since last time, but still the same problem occurs. Is there any way that I can adjust the code so that the left hand side doesn't keep getting chopped off?
.pageContainer {
margin-left: auto;
margin-right: auto;
width: 100%;
height: auto;
padding-left: 1.82%;
padding-right: 1.82%;
position:relative; }
#LayoutDiv1 {
clear: both;
margin: auto;
width: 100%;
display: block;
text-align:center;
position: relative; }
#Box {
width: 487px;
height: 181px;
position: absolute;
left: 50%;
top: 236px;
margin-left: -244px;
z-index:6; }
The html:
<body>
<div class="pageContainer">
<div id="LayoutDiv1">
<div id="Twitter">
<img src="images/TwitterNORMAL.png" onmouseover="this.src='images/TwitterHOVER.png'" onmouseout="this.src='images/TwitterNORMAL.png'"/>
</div>
<div id="Facebook">
<img src="images/fbNORMAL.png" onMouseOver="this.src='images/fbHOVER.png'" onMouseOut="this.src='images/fbNORMAL.png'"/>
</div>
<div>
<img id="Box" src="images/BOX.png" width="487" height="181">
</div>
</div>
</div>
</body>
The smarter way in 2012 to do this is to use Media Queries, some inspiration here
You basically create another style sheet which is loaded only for smaller screens. It might seem like an overkill now, but as your website grows, you will thank me for suggesting this (or you cannot ;))
Also, don't do margin-left: -244px;, its hacky and can cause cross browser issues. Show us some HTML and we shall show you a cleaner way.
Are you including a viewport meta tag? It should eliminate any scaling issues you may be having in mobile.
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
To you CSS: <div>s are block elements, and their default behavior is to expand the width of their parent (100%). Those CSS declarations aren't necessary.
From your code, and layout, it doesn't look like you need #LayoutDiv1 or to use positioning.
This simpler code takes care of the left-side-cutoff (here's a fiddle):
.pageContainer {
margin:0 auto;
}
#LayoutDiv1 {
margin: auto;
text-align:center;
}
#Box {
width: 487px;
height: 181px;
top: 236px;
margin:236px auto 0;
}
And like a prev poster mentioned, you could add a #media query to load a smaller image for #Box on mobile (you can simply add a line or two [or 200] to your existing CSS file):
#media only screen and (max-width: 767px) {
#Box { background:url('imgs/mobile-hero.jpg'); }
}

Footer won't center on the bottom of the page

My footer is perfectly positioned on every computer screen.
But, when I test it on an Iphone, the footer get stuck in the middle of the page and is not repeating itself in a horizontal way.
What can I do, so the footer also stays on the bottom of an Iphone screen and other smartphones?
This is the CSS of my footer:
#footer {
position:absolute;
bottom:0;
width:100%;
height:270px;
background-image:url(images/footer.png);
}
Change the position to fixed, hope that can solve this question.
#footer {
position:fixed;
bottom:0;
width:100%;
height:270px;
background-image:url(images/footer.png);
}
First, I hope it's for a static page, as dynamic pages could give you even more troubles.
Anyway, it's not a good idea to put the footer at 0 to the bottom, if I had bigger fonts or small resolution (like using a notebook or a smartphone), the content will go below the footer, which is what probably happens to your page. There is a lot of code around the web answering that specific question. And it's called 'sticky footer'.
This is a copy/paste of that page. I hope no one get's offended, there's no need to rewrite it all if it's already out there. If you are not satisfied, just google 'Sticky footer':
How to use the CSS Sticky Footer on your website
Add the following lines of CSS to your stylesheet. The negative value for the margin in .wrapper is the same number as the height of .footer and .push. The negative margin should always equal to the full height of the footer (including any padding or borders you may add).
* {
margin: 0;
}
html, body {
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -4em;
}
.footer, .push {
height: 4em;
}
Follow this HTML structure. No content can be outside of the .wrapper and .footer div tags unless it is absolutely positioned with CSS. There should also be no content inside the .push div as it is a hidden element that "pushes" down the footer so it doesn't overlap anything.
<html>
<head>
<link rel="stylesheet" href="layout.css" ... />
</head>
<body>
<div class="wrapper">
<p>Your website content here.</p>
<div class="push"></div>
</div>
<div class="footer">
<p>Copyright (c) 2008</p>
</div>
</body>
</html>
EDIT: It has exactly the behavior I stated. If you zoom your page (Control + '+'), you'll see how the content goes below the footer.
