IFRAME and conflicting absolute positions - css

I would like to have an IFRAME dynamically sized using the following CSS:
#myiframe {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
}
However, no browser seems to support this.
In good browsers I could wrap the IFRAME in a DIV with the quoted CSS style and set the height & width of the IFRAME to 100%. But this does not work in IE7. Short of using CSS expressions, has anyone managed to solve this?
Update
MatTheCat answered with a scenario that works if the IFRAME is located directly under the body and the body/html tags have height: 100% set. In my original question I did not state where the IFRAME was and what styling applied to it's container. Hopefully the following addresses this:
<html>
<body>
<div id="container"><iframe id="myiframe"></iframe></div>
</body>
</html>
and let's assume the following container CSS:
#container {
position: absolute;
top: 10px;
bottom: 10px;
left: 10px;
right: 10px;
}
if you now place height: 100% on the IFRAME it will not size correctly.

Use a div for the padding on all sides. Place the iframe in it using 100% of its parent div.
http://jsfiddle.net/sg3s/j8sbX/
Now there are a few things you need to remember. An iframe is originally an inline-frame, so while modern browsers don't care, set display:block on it. By default it also has a border. Any stying we want to be done needs to be done on the iframe container instead or we'll break the 100% container boundry.
And this is how we would put an element above it:
http://jsfiddle.net/sg3s/j8sbX/25/ (edit: my bad, you actually need to set border=0 on the iframe for IE7)
Should work fine in IE7+ (IE6 doesn't like absolute positioning + using top/right/bottom/left to give it layout)
Edit Some extra explanation
We need to style the iframe container mainly because an iframe on itself doesn't let itself be sized with top/left/bottom/right. But what will work is setting its width and height to 100%. So starting from there we simply wrap the iframe in an element which we can reliably style to make less than the window 100%, the size which elements default to when none of their parents have a static height/width.
Thinking about it we can actually drop the absolute and block. http://jsfiddle.net/sg3s/j8sbX/26/ Might want to doublecheck IE7 on that though.
After we make the iframe 100% high and wide we cannot put any margin, padding, or border on it because that will be added to the already 100% height & width. Thus making it larger than its container, for divs that will result in an overflow:visible, simply showing everything going over the edges. But that in turn would mess up the margins, paddings and offsets we gave our elements.... In fact to make it be only the 100% height and width you have to make sure you removed the iframes default border.
Try it out by adding a larger border (like 3px) in my example to the iframe, you should easily be able to see how it's affecting the layout.

Why don't you use height & width? You'd still get an absolute position by setting top/bottom & left/right, as in the example below.
<!DOCTYPE HTML>
<html>
<head>
<style type="text/css">
html, body {
margin:0;
padding:0;
border:0px;
height:100%;
width:100%;
}
#container {
position: absolute;
top: 10px;
bottom: 10px;
left: 10px;
right: 10px;
}
#myiframe {
position: absolute;
top: 0%;
left: 0%;
height: 100%;
width: 100%;
}
</style>
</head>
<body>
<div id="container"><iframe id="myiframe"></iframe></div>
</body>
</html>
This works for me (Tested on IE9).

html,body {
margin:0;
padding:0;
height:100%;
min-height:100%;
}
#myiframe {
width:100%;
height:100%;
border:0;
}
work fine for me even with IE7.

I would say take a look at this stack overflow question. It might help:
Make Iframe to fit 100% of container's remaining height

You can try to use this:
document.getElementsByTagName('iframe')[1].style.borderWidth = '0px';
document.getElementsByTagName('iframe')[1].style.backgroundColor = 'green';

How to give footer background color for the whole width of the browser with fixed parent div

I am working on Bootstrap theme where its responsive. I disable the responsiveness on a child theme by adding a code in functions.php. All works well , no problem.
Now the parent container, is now fixed:
HTML:
<div class="container">
CSS:
.container{width: 940px;}
But I would like the footer section to have sitewide background color. How do I able to do this?
I have tried setting different methods like width:auto, width: 200% ,but its not giving me the desired result.
Supposing this is the footer section:
<footer>
My footer
</footer>
My attempted CSS on a child theme(not working)
footer {
background: #CCCCCC;
width:100% !important;
position:absolute !important;
}
Also is this possible without setting too many !important on CSS property? Thanks.
If your footer is inside the div.container which has width:940px; then giving your footer 100% width will make it 940px wide.
You need to have the footer outside the container to give it 100% width of the body.
When you give 100% width, the element gets its container's width. So in your code, even with the important keyword, it'll get the container's width (because that what 100% is supposed to do).
Just take the footer outside of the container.
Then it'll work and you won't need this !important keyword.
As others have mentioned, removing the footer from the parent container of .container will allow the width of it to be the entire size of the viewport/document.
If you are unable to change this level of structure of the HTML due to your template, you can fake the width using pseudo-elements, like so:
footer {
position: relative;
background-color: lightblue; /* Match the color of the body background */
}
footer::before, footer::after {
content:"";
position: absolute;
top: 0;
bottom: 0;
width: 9999px;
/* some huge width */
background-color: inherit;
}
footer::before {
right: 100%;
}
footer::after {
left: 100%;
}
See jsFiddle.
Taken from CSS Tricks: Full Browser Width Bars

Overflow-x:hidden doesn't prevent content from overflowing in mobile browsers

I have a website here.
Viewed in a desktop browser, the black menu bar properly extends only to edge of the window, since the body has overflow-x:hidden.
In any mobile browser, whether Android or iOS, the black menu bar displays its full width, which brings whitespace on the right of the page. As far as I can tell, this whitespace isn't even a part of the html or body tags.
Even if I set the viewport to a specific width in the <head>:
<meta name="viewport" content="width=1100, initial-scale=1">
The site expands to the 1100px but still has the whitespace beyond the 1100.
What am I missing? How do I keep the viewport to 1100 and cut off the overflow?
Creating a site wrapper div inside the <body> and applying the overflow-x:hidden to the wrapper instead of the <body> or <html> fixed the issue.
It appears that browsers that parse the <meta name="viewport"> tag simply ignore overflow attributes on the html and body tags.
Note: You may also need to add position: relative to the wrapper div.
try
html, body {
overflow-x:hidden
}
instead of just
body {
overflow-x:hidden
}
VictorS's comment on the accepted answer deserves to be it's own answer because it's a very elegant solution that does, indeed work. And I'll add a tad to it's usefulness.
Victor notes adding position:fixed works.
body.modal-open {
overflow: hidden;
position: fixed;
}
And indeed it does. However, it also has a slight side-affect of essentially scrolling to the top. position:absolute resolves this but, re-introduces the ability to scroll on mobile.
If you know your viewport (my plugin for adding viewport to the <body>) you can just add a css toggle for the position.
body.modal-open {
// block scroll for mobile;
// causes underlying page to jump to top;
// prevents scrolling on all screens
overflow: hidden;
position: fixed;
}
body.viewport-lg {
// block scroll for desktop;
// will not jump to top;
// will not prevent scroll on mobile
position: absolute;
}
I also add this to prevent the underlying page from jumping left/right when showing/hiding modals.
body {
// STOP MOVING AROUND!
overflow-x: hidden;
overflow-y: scroll !important;
}
As #Indigenuity states, this appears to be caused by browsers parsing the <meta name="viewport"> tag.
To solve this problem at the source, try the following:
<meta name="viewport" content="width=device-width, initial-scale=1, minimum-scale=1">.
In my tests this prevents the user from zooming out to view the overflowed content, and as a result prevents panning/scrolling to it as well.
This is the simplest solution to solve horisontal scrolling in Safari.
html, body {
position:relative;
overflow-x:hidden;
}
body{
height: 100%;
overflow: hidden !important;
width: 100%;
position: fixed;
works on iOS9
Keep the viewport untouched: <meta name="viewport" content="width=device-width, initial-scale=1.0">
Assuming you would like to achieve the effect of a continuous black bar to the right side: #menubar shouldn't exceed 100%, adjust the border radius such that the right side is squared and adjust the padding so that it extends a little more to the right. Modify the following to your #menubar:
border-radius: 30px 0px 0px 30px;
width: 100%; /*setting to 100% would leave a little space to the right */
padding: 0px 0px 0px 10px; /*fills the little gap*/
Adjusting the padding to 10px of course leaves the left menu to the edge of the bar, you can put the remaining 40px to each of the li, 20px on each side left and right:
.menuitem {
display: block;
padding: 0px 20px;
}
When you resize the browser smaller, you would find still the white background: place your background texture instead from your div to body. Or alternatively, adjust the navigation menu width from 100% to lower value using media queries. There are a lot of adjustments to be made to your code to create a proper layout, I'm not sure what you intend to do but the above code will somehow fix your overflowing bar.
Creating a site wrapper div inside the body and applying the overflow->x:hidden to the wrapper INSTEAD of the body or html fixed the issue.
This worked for me after also adding position: relative to the wrapper.
No previous single solution worked for me, I had to mix them and got the issue fixed also on older devices (iphone 3).
First, I had to wrap the html content into an outer div:
<html>
<body>
<div id="wrapper">... old html goes here ...</div>
</body>
</html>
Then I had to apply overflow hidden to the wrapper, because overflow-x was not working:
#wrapper {
overflow: hidden;
}
and this fixed the issue.
Adding a wrapper <div> around the entirety of your content will indeed work. While semantically "icky", I added an div with a class of overflowWrap right inside the body tag and then set set my CSS like this:
html, body, .overflowWrap {
overflow-x: hidden;
}
Might be overkill now, but works like a charm!
I encountered the same problem with Android devices but not iOS devices. Managed to resolve by specifying position:relative in the outer div of the absolutely positioned elements (with overflow:hidden for outer div)
I solved the issue by using overflow-x:hidden; as follows
#media screen and (max-width: 441px){
#end_screen { (NOte:-the end_screen is the wrapper div for all other div's inside it.)
overflow-x: hidden;
}
}
structure is as follows
1st div end_screen >> inside it >> end_screen_2(div) >> inside it >> end_screen_2.
'end_screen is the wrapper of end_screen_1 and end_screen_2 div's
As subarachnid said overflow-x hidden for both body and html worked
Here's working example
**HTML**
<div class="contener">
<div class="menu">
das
</div>
<div class="hover">
<div class="img1">

easiest way to solve this , add
<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
I had tried many ways from replies in this topic, mostly works but got some side-effect like if I use overflow-x on body,html it might slow/freeze the page when users scroll down on mobile.
use position: fixed on wrapper/div inside the body is good too, but when I have a menu and use Javascript click animated scroll to some section, It's not working.
So, I decided to use touch-action: pan-y pinch-zoom on wrapper/div inside the body. Problem solved.
I've just been working on this for a few hours, trying various combinations of things from this and other pages. The thing that worked for me in the end was to make a site wrapper div, as suggested in the accepted answer, but to set both overflows to hidden instead of just the x overflow. If I leave overflow-y at scroll, I end up with a page that only scrolls vertically by a few pixels and then stops.
#all-wrapper {
overflow: hidden;
}
Just this was enough, without setting anything on the body or html elements.
Setting overflow-x to 'clip' instead of 'hidden' also prevents unwanted scrolling on touch-devices, with wacom-pens, with shift-scrollwheel or any other programmatic scrolling. On the downside, it also prevents programmatic scrolling with javascript.
https://developer.mozilla.org/en-US/docs/Web/CSS/overflow#clip
The only way to fix this issue for my bootstrap modal (containing a form) was to add the following code to my CSS:
.modal {
-webkit-overflow-scrolling: auto!important;
}
step 1: set position to fixed to the element that goes out from the viewport. In my case it is:
.nav-links {
position:fixed;
right:0px;
background-color:rgba(0,0,0, 0.8);
height:85vh;
top:8vh;
display:flex;
flex-direction:column;
align-items: center;
width:40%;
transform: translateX(100%);
transition: transform 0.5s ease-in;
}
Step2: add a css property to body and html as:
body, html{
overflow-x: hidden;
}
I didn't add any wrapper. Only these two steps worked for me. The project I am working on is an angular project.
The following works
body,
.innerbodywrapper{
overflow-x: hidden;
position: fixed;
width: 100%;
height: 100vh;
}
Solution that properly work for mobile device with flex positionning top :
html,body {
width: 100%;
margin: 0;
padding: 0;
}
and in web page :
<meta name="viewport" content="width=device-width, user-scalable=0">
Don't forget to positioning this css in the different webpage main divs :
height : auto !important;
html, body{ overflow-x: hidden; position: relative; } Just try like this where you have added the overflow-hidden.

How to expand the height of the page in blueprint?

Using blueprint.css, is there a way to stretch a <div> to the height of the page? I know how to do it in pure CSS, but nothing I've found suggests how to do it with blueprint, so I'm left with a <div> that has a background that stops halfway down the page (which looks terrible).
There isn't a Blueprint class for this and a quick grep will show that the necessary CSS doesn't show up in the project.
Compass handles it with a set of stretch mixins. stretch-y adds the following CSS to the element:
bottom: 0;
position: absolute;
top: 0;
Since absolute positioned elements don't interact with floats, you'll need a in a div with the background-color that you want and the appropriate width (i.e. give it the right span-# class).
The purely presentational div feels like a hack, but I like it better than the Faux Column method.
You might want to to include:
html, body {
height: 100%;
}
and the following for your container, to give it 100% height and so the div's absolute positioning happens inside of it:
min-height: 100%;
height: auto !important;
height: 100%;
position: relative;
and maybe even this IE hack, though it might only be necessary with a footer:
<!--[if !IE 7]>
<style type="text/css">
#wrap {display:table;height:100%}
</style>
<![endif]-->

Without javascript, can I style a div to cover up the current document including its margins?

it can be done using javascript, but with CSS alone, is it possible to style a div to overlap exactly any page's document content or viewport (to apply an opaque gray layer on the page)? since a page can have margin for it body element, so styling a div to the width of its body element won't do. (needs to work in IE 6 too)
IF you have a <div> like this:
<div id="cover"></div>
These styles should do it:
#cover {
background-color: #ccc;
opacity: 0.6;
filter:alpha(opacity=60);
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
Tested on a page where the body has a margin and it covered the entire viewport for me on IE and FF.
height: 100% won't cover the viewport if document length is less than height of viewport. In this case you will have to use Javascript.
would it be cheating to use IE's ability to execute javascript in CSS?
width:expression(document.body.clientWidth)

Why is CSS height:100% not working in IE6?

I have an IE6 absolute position div that I want to be full screen (100% width and height). It's being used as a "loading, please wait" message while the data loads on the page.
It appears that ie6 does not recognize the css of "height:100%".
Any work arounds?
Also, in some older browsers you need to set the height of the html tag as well:
body, html {
height: 100%;
}
Height 100% on a div needs it's parent to also have a height defined in IE6. Try this:
body{
height:100%;
}
Also, and this might have flaws of its own, you could do the following:
#fullScreenDiv {position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
}
It'll maybe screw with nested components and their floats and so forth, but it would definitely, with a doctype, make the div full screen.
