background image shifts depending on browser

Background image of leaves looks great in Safari. Not so good in Chrome and FF.

/*background image*/
#supersize img
{
	height: 100%;
	position: absolute;
	width: 100%;
	z-index: -100;
	top: 1px;
}
	
	#supersize{position:fixed;z-index:0;overflow:hidden;width:100%;height:100%;top:0;}

Why don't you just set it as the background of
<div id="supersize">
and forget the <img>.

Neil_Bradley

I agree with GaryC123
Update your css to something like:
#supersize{
background: url(yourimage.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

Didn't work. Maybe the end div for the supersize is in the wrong spot. I put it right above the closing body tag. The background does not extend the full page.

Here is link:

http://plymouthwisconsin.com/test.css

#supersize{
		  background:url(img/back_fall_tree.jpg);
		  no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;

Neil,

Tried your solution but it didn't work either. Here is a screen shot. As you can see, the background only fills the top and bottom of the screen. It is supposed to fit the left and right margins as well.

Gary,
Your solution didn't work either. Got no background image at all.
Geez, this isn't supposed to be this hard!

Is this supposed to be one declaration?
background:url("img/back_fall_tree.jpg") no-repeat scroll 0 0 / cover rgba(0, 0, 0, 0);

Gary

Do an hard refresh, it looks fine to me with it on the body tag.

n.b.
css cover is a CSS3 attribute so won't work in <=IE8

Neil_Bradley

By removing the body colour you will allow the background image to show up. Your screen shot shows the white body colour over the top of the html style (which contains the image).
The image is there, just covered.

Hi Gary,
you are correct re <=IE8.
” background-size:cover ” is the best solution for this issue. for ie7 and ie8 you could use jquery background image re-size plugin (Please visit the link: http://github.com/louisremi/jquery.backgroundSize.js).
You can use conditional statement only for IE7 & IE8 (helps to optimize site loading time).

Unfortunately when using more advanced CSS techniques to solve a problem or achieve an effect there will always need to be some compromise or fall back code for older browsers.

Neil, Your solution worked but alas, I do have to allow for older browser users so I cannot use it.

Gary, I cannot get your solution to work in Safari but it does work in Chrome and ff. Is there a workaround for Safari?

Neil_Bradley

Visit https://github.com/louisremi/jquery.backgroundSize.js for a fall back solution.

The transitional doctype is going to contribute to cross-browser issues. You should be using HTML5 or XHTML strict.

I don't know that the 28 validation errors are contributing to the problem, but they are certainly not helping to create the desired rendering.

COBOL, I am using html5. When I create a new page in DW, that is the setting that I select.
See screen shot. Not sure why it appears that I am not using the right type of doc

The validation errors are mostly out of my control. They are all in the code for the animation. The animation is done with cu3ox which is a software that was recommended by an expert of expert-exchange.

after some thought i decided to go with the following solution

html {
background: url(img/back_fall_tree.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

This what is in the head of the rendered page:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

For the page: http://plymouthwisconsin.com/index.html

Dreamweaver development tools and the way the page is actually generated and rendered are two different thing. The only way you know how the code is be ing seen by the client is to do view source in a real browser, not Dreamweaver.
