I'm using jQuery's .css() method to set the background image of a div. The HTML in its final state is thus:
<div id="front-page-bg" style="background-image: url(http://peterfcarlson.com/wp-content/uploads/2011/09/ert-011.jpg); display: block; "></div>
It works fine, however, I'm getting an error/warning in Chrome, where the background-image property is struck through as though it's being ignored due to bad input, even though it is obviously being applied. Why would this be? Is it a problem with Chrome, or on my end?
I've tested the page in FF and IE, where it also seems to work without any errors or similar warnings. Any ideas about why this might be happening, and perhaps more importantly, should I ignore it, since the page seems to be working?
EDIT:
By inspecting more deeply (ignoring the first misleading 404 problem with image), seems that developer tools is ignoring the style definition; infact it applies a
not-parsed-ok class which appends the warning icon, and an overloaded class which causes the line-through.
The overloaded class is not appended if using background in place of background-image css definition.
But to discover the reasons of this behaviour would be necessary to analyze the developer tools source code.
My guess is that is a developer tools bug/incomplete feature.
This is my own test:
as you can see the image used is local, and have apix. And this is the resulting inspection:
Testing with a non existent css property, it shows the identical behaviour:
Your referenced image has some strange web server issues:
infact it is returning a 404 error (maybe timeout?), then a redirect.
So you should check the image and the web server path, not your actual html code.
Even trying to put in actual html code, the error is the same:
This is the actual response of your web server, instead of your image:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
html,body{height:100%;width:100%;margin:0;padding:0;}
body{overflow:hidden;background:#EDEDED url(http://peterfcarlson.com/wp-content/themes/comingsoon/pfc.png) center center no-repeat}
</style>
</head>
<body>
</body>
</html>
The problem is the DevTools/WebInspector bug.
DevTools UI code just shows the data not always correctly generated by the back-end part of DevTools.

#IsaacLubow; Both Chrome & Safari developer tool show that warning error. Then question is
Why they show a warning ?
Answer:- Both Chrome & Safari developer tool show warning when the property is not understand & recognized by them.
for example:- write -moz-border-radius in the css. Then check the page in chrome or safari. It's shows the same error which you have.
Then the second raised question is
But background-image property is recognized by all browsers !
Answer :- Yes; background-image property is recognized by all browsers & the image is still shows in the website but the way we define the image is cause for that warning/error. In your example if you define background-image property inside the html tag instead of css. It's shows the warning/error.
Check this example the first div images show an warning but second div is not show any warning:
http://jsfiddle.net/sandeep/RDmRz/3/show
So; why that's happen ?
Because assigning attributes in html tag is a Deprecated method means
Those deprecated features can still be used, but should be used with
caution because they are expected to be removed entirely sometime in
the future. You should work to remove their use from your code.
Check what mozilla said about that https://developer.mozilla.org/en/JavaScript/Reference/Deprecated_Features
https://developer.mozilla.org/en/DOM/HTMLImageElement
So; Developer tool are updated as per the new html standards & after introducing HTML4 some properties deprecated & outdated.
Check this for more http://fantasai.tripod.com/qref/HTML4/deprecated.html
http://www.createafreewebsite.net/html_tutorial/body_tag.html.
It's good to write background-image in css instead of html tag.

Your image is not coming up, instead we are getting a 404 error. I noticed that you are using a wordpress site from the structure of your image url, what we might be looking at is not your image but the image included inside your 404.php page inside your theme.
The html that is returned is the following:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
html,body{height:100%;width:100%;margin:0;padding:0;}
body{overflow:hidden;background:#EDEDED url(http://peterfcarlson.com/wp-content/themes/comingsoon/pfc.png) center center no-repeat}
</style>
</head>
<body>
</body>
</html>
And this is the image being loaded instead: http://peterfcarlson.com/wp-content/themes/comingsoon/pfc.png
I'm quite sure that if you check your 404.php page from your theme that is what you will find. So you might want to re-upload the image and use the new url.
Comment
I know the question was answered but wanted to chime in with my results as to what i found. I noticed that, for some reason, when you specify a background-image to an element it sometimes drops a warning in a webkit browser, which is the issue that the OP was having. But i noticed that the warning disappears when the background shorthand is used instead.
Like so:
background:#ffffff url('image.png') repeat scroll right top;
I modified #sandeep's demo to show how it works:
Here is the full fiddle: http://jsfiddle.net/RDmRz/7/
And demo page: http://jsfiddle.net/RDmRz/7/show/
Check the page with the developers tools and switch between the divs to show how it is working for the "works" images and not working for the others.

When I inspected my webpage, and clicked for a particular element, which is not rendered as I wanted, I saw some faults in the Css used in the style section of the browser. How to find that particular Css in the Code base.
You should see, in addition to the CSS and the warning about a fault, an indication of which file that CSS came from.
For instance in this trivial example:
<style>
body {
background: rubbish;
}
</style>
<body></body>
I saw:
Notice that to the right of the faulty CSS is the file which it came from.
Search in that file for the CSS that is causing a problem
I'm looking for a way to append styles to my stylesheet dynamically with Javascript.
In today's browsers, I can use this for example:
<style>
#id{background-color:#F00;color:#000;}
</style>
<div ID="id">Test1</div>
<div ID="id2">Test</div>
<script>
document.getElementById('ID').innerHTML+="#id2{color:#00F}";
</script>
The above would change the color of Test from black to blue because of the javascript, but this code does NOT work with older browsers such as Internet Explorer 7.
In Internet Explorer 7, I narrowed the problem down to the fact that it produces a javascript warning symbol at the bottom left corner when it is expected to set the innerHTML value of the style element.
I tried replacing:
document.getElementById('ID').innerHTML+="#id2{color:#00F}";
with:
document.getElementById('ID').appendChild(document.createTextNode("#id2{color:#00F}"));
and I'm still unsuccessful.
I need javascript for this because I want to set the background image for multiple elements at once, and by ramming in CSS code, I can call the image only once. If I used native javascript properties for each element, then I'm going through numerous elements as well as requesting the load of the same element numerous of times, and if IE is bad with caching, then burden will be placed on the server.
What can I do in Javascript to append CSS data to the style element that works with IE 7? I'm looking for something simple.
Well, I went back to the olden days, and managed to pull this off in IE 7:
document.write('<style>'+d+'</style>');
the variable d is the actual rules to insert.
I understand this is a slower method as it creates numerous <style> tags which is bad HTML practice, but the idea works in IE7.
After spending a while creating an online portfolio, then uploading it, I noticed an issue with one of my sections. On the "Advertisement" section, I noticed it was not displaying the information, just the title. So, I kept on re-pushing the stylesheet.css, even editing it, and it would still look the same. The HTML, CSS, and JS is working how I wrote it. But it is just the section that is not showing. After browsing online and on stackoverflow for an answer, I believe it has to do with Firefox. When using Firebug, I noticed the section's background has been removed, causing the entire section to "disappear." It works just fine on Chrome. I'm not worried about IE, I know that browser has some issues in itself. Anyway, would anyone on here have an idea to resolve this issue, if I can? Or even, what could be causing this issue?
Here is my website to see for yourselves. www.voelkerdesigner.com
Cheers!
It is the opposite for me your entire site works in firefox for me but not in chrome, looking through your code, its being caused by your naming conventions. Namely #advertise
I use the adguard extension in chrome and below is the css it plugs into my html pages to hide ads, so im guessing your using an adblocker in firefox
#adsense_top, #adsensewide, #adspace, #adspace_top, #adspot-300x250-pos-1, #adspot-300x250-pos-2, #adswidget1-quick-adsense, #adswidget2-quick-adsense, #adtext, #adtop, #adv-masthead, #adv-top, #advert1, #advert2, #advertbox3, #advertise, #advertisement1, #advertisetop, #advertising-container, #advertising_wrapper {
display: none!important;
}
Might as well post a random answer on this... As i wont visit posted links by new users.. i'm just gonna guess that your background image might not be 100%...
In general i use background-image instead of background.. Short hand can be a little pain and breaks in some browsers if not perfect.
so i would compare against the following example
background-image:url('images/mybg.jpg');
background-image:url('http://somesite.com/images/mybg.jpg');
Basically alot of people do not use the url and just go straight for a file name or dont quote it.. And have seen that be the problem in the past, so do use the url('') method.
Otherwise if it still fails to work and you know the image is absolute, you would then have some other css that is either over riding your elements background or is preventing it from loading.
Another trick is using your console / inspect element to manually inject the background-image and see if that works... So once the page has loaded in chrome, inspect the element as normal.. And double click on your css property listing as you can add your own styles this way and if it fails, then its not the markup but something else.
So, I've tried everything I can think of, or have found regarding how to make sure that IE 8 will work with the 'content' property in my page.
No matter what I try though, when viewing in IE9 using F12 dev tools to view in IE8 standards mode, the page simply won't load AT ALL. I get a "page error" when viewing in Adobe's browser tester as well.
As soon as I remove my "content" property line from my css, then it works fine, but of course, then I lose my cool drop-shadows that I'm wanting to use in all the other browsers.
here's the page: http://saks-jewelers.com (the featured product section towards the bottom).
Any thoughts on what I'm missing? (this site is run using magento CE 1.7)
The content property will not work in IE8 unless you specify a doctype. This is according to W3C.
Put this at the top of your code and let us know if it works:
<!DOCTYPE html>
Both people on IE8 are going to be disappointed! Did you try checking the inspect element in ie8 to see if the error is more specific?
Is your drop-shadow defined in the last CSS loaded?
I am having problems with my webpage. On all browsers the div aligns perfectly. However, on all versions of Internet Explorer the Div shows out of line. Here is an image of the difference:

I would really love the help, IE has done this to me several times. I would love to learn what to do in these types of situations. I read somewhere about an IE specific CSS file that would fix this but I did not fully understand what needed to be changed in this new CSS file. All help appreciated.

Try fixing the issues presented by the W3 validator. http://validator.w3.org/check?uri=http%3A%2F%2Fkynikosdesign.com%2Fcontact.php&charset=%28detect+automatically%29&doctype=Inline&group=0&verbose=1
You can add this and it should work (at least it did just through in-browser modifications)
after your normal css
<!--[if IE]>
<style type="text/css">
#mainbox{padding-left:0;}
#servicesright{float:left;}
</style>
<![endif]-->
That aside, you're also missing some closing tags it would seem and probably the reason for the weirdness.
Issues I detected on your page structure so far (which are causing the display issue):
#main-container should not have width
you are using table for your form layout which is a big mistake (it's pushing the whole content together down)
as a workaround removing width in (1) and width=100% in (2) will fix your problem butI highly recommend to follow good practices for your page layout. (i.e. using div instead of table).
