Flickering line under background image in Firefox on resize - css

I'm building a website that has a full width background image in the header that resizes with the page. There is an unusual flickering horizontal line that appears under the image when it is resized in Firefox. The line does not appear at full with, but blinks on and off when the size is changed. The line appears at the bottom of the background image, not the bottom of the header element.
It appears in the MacOS build of Firefox only when I tested it in OSX 10.8.4, Firefox 23.0. The problem did not appear with Windows 8, Firefox 23.0.1, or in other browsers that I have tested.
Here is the code on my header:
<header>
<h1><span>Sound Soups on Madison - Healthy & Convenient Alternatives for Your Busy Work Week</span><img src="images/sound-soups.jpg" id="logo" alt="Sound Soups"></h1>
<nav id="nav-main">
<?php echo makeLinks($nav1); ?>
</nav>
</header>
header{
padding:0 2.12765957% 35px;
overflow:hidden;
background-image:url('../images/bg-header.jpg');
background-repeat:no-repeat;
-webkit-background-size: 100%;
-moz-background-size: 100%;
-o-background-size: 100%;
background-size: 100%;
}
I've tried using cover instead of 100% for the background size, and putting padding or a border under the header. Googling the problem didn't turn up anything. Thanks in advance if anyone knows the answer here.

EDIT:
The issue seems to be related to how FireFox scales the background image. The following seems to fix it for me with FireFox 23.0.1 , OSX 10.8.4
In style.css, try changing the background-size property in the header rule from 100% auto to 99.99% auto, ie
header {
background-image: url("../images/bg-header.jpg");
background-repeat: no-repeat;
background-size: 99.99% auto;
margin: 0;
overflow: hidden;
padding: 0 2.12766% 35px;
}
If I'm understanding your question correctly, check the top of the stylesheet # http://soundsoups.julie-edwards.com/css/responsive.css
You have
header{
background-image:url('../images/none.png');
padding-bottom:15px;
border-bottom:2px solid #7a918c;
margin-bottom:20px;
}
I think the border-bottom is the cause of the problem.
Good luck!

Had the same problem for a background-sized image on the body element.
I fixed it by applying the background-sized image to a positioned div element.
If that can be of any help.

I solved this problem by converting my .jpg background image to a .png. In case anyone else runs into this and can't change background-size, try this.

background image for homepage

I am quite new to the css and bootstrap i have searched and tried the w3c solution and also the SO but did not work well. Actually i want to have an image as a background on my homepage. on which there would be my content like 3 small buttons/icon in the middle of the page.
I have tried this
<div id="homepage">
</div>
css:
#homepage{
background: url(../images/homepage.jpg);
background-size: 100% 100%;
background-repeat: no-repeat
}
but it is not working.
2nd Solution:
Second thing which i tried was to include a img tag then add my content and drag to the middle by absolute position which i think is not a good way because responsiveness did not remain there.
Can any one help me in this regard.
Assuming you double checked the image path,I think the problem is the size of the div.
try giving your div a fixed width and height in order to test if at least this way the image is showing.
<div id="homepage" style="width:500px;height:300px">
</div>
Then check out how to use the bootstrap grid system in order to make your div as big as you wish.
You can try this:
#homepage{
background: url(https://paulmason.name/media/demos/full-screen-background-image/background.jpg);
background-repeat: no-repeat;
background-size: cover;
height: 100vh;
width: 100%;
}
http://jsfiddle.net/y558vo9a/
if you want the background image to be in your index page, there is no need in adding '../' and no need in adding background-size, -repeat when you can actually set your code so;
background: url(images/homepage.jpg) no-repeat 50% 50%;
but if it works for you, you can use it so. And i also noticed, you forgot to close your background-repeat with ';'

CSS3 IE 11 background image not appearing works in chrome, edge, safari just not ie

my css looks like this:
body {
background: url(images/Gabrielheroimage3.jpg);
background-repeat: no-repeat;
background-size: contain;
max-height: 700px;
max-width: 1300px;
}
tried removing max-height and width but didn't help. also tried background-image rather than background and that didn't help either. I appreciate any suggestions! Thank you!
background-image: url(images/Gabrielheroimage3.jpg);
the page having a problem was literally just a background image with navigation. Took the background image out of the css file and add div img tag and styled it within html and it worked on IE and all the other browsers for that matter.

css repeat-y not working in IE8

I am using a div tag and I am applying css to it.
Please find below the div tag
<div class="testcss">
</div>
My css class is as follows
.testcss
{
background-image: url('images/imag2.gif');
background-repeat: repeat-y;
background-position: bottom-left;
padding-left: 10px;
padding-right: 10px;
}
The div is showing background image and displaying properly in Mozilla other browsers but it is not working in IE8 and IE9.
Even it is working fine in IE10.
There is some issue with background-repeat: repeat-y not working properly in IE8 and IE9.
Is there some way that we can fix this in IE8 and IE9.
Any help would be greatly appreciated.
Thanks in Advance.

Rahul Rathi
I believe your syntax is wrong, and no.. it should work in IE8 and IE9 ... try:
.testcss {
background: url('images/imag2.gif') bottom left repeat-y;
padding-left: 10px;
padding-right: 10px;
}
http://jsfiddle.net/feitla/85XFu/
PS - tested in IE9... background repeated just fine. Make sure your div actually has a set height/width if it is empty.
I agree with #feitla on the fact that your syntax is wrong. You can't use bottom-left as it doesn't exist in the background property for CSS.
I also agree that you should simply use background: url('images/imag2.gif') left repeat-y as the bottom is not needed because it's already repeating in the Y axis and spanning all the height of the container.
Last but not least, you do have to set a width and a height to your element if it's empty (as in with no other markup) because otherwise you would only be able to see 20 pixels in width because of your padding left and right.
I think that the lesson to take from this is that it's safer to use shorthand styles as it makes your code cleaner and easier to read.
You would end up with:
HTML
<div class="testcss"></div>
CSS
.testcss {
background: url('images/imag2.gif') repeat-y left;
padding: 0 10px;
}
Read more about how to use shorthand code as it makes writing CSS a lot cleaner and more fun... and it's not as hard as it may seem, here's a link to this specific issue and shorthand css for background.

Background Picture on a Responsive Website doesn't fit when the screen size changes

How can I get the background of a Responsive website to adapt and move with the rest of the content on the Website?
My background is split doesn't cover the entire background, only partially to create an effect where each sides are of a different color (gray).
However, when I change the size of the screen, all of the elements will be moved and the background will not be positioned as it was initially.
How could I go about making sure that no matter what the size of the window is, the "gray bars" will always fit with main content?
If you look at this picture, this is how it should look like:
Also here is the script for the background image as well as the site wrapping:
.gray {background:url(http://frenchegg.com/images/gray.png) no-repeat; height:100%;}
.lgr {background-size:85% 100%; background-position:center;}
.main-content p {
color:#555;
}
.site-wrap {
position:relative;
min-height:100%;
background-color:#ebebeb;
}
You can find the website here.
Ok, you're page may need a little restructuring, but I believe I have a solution for you.
Initially, the main problem stems from background size being set to percentage widths (note background-size is a css3 property and not fully supported... but thats another issue).
For a proof of concept and for you to see what you're going to have to change, try to following:
Remove the background on 'gray' (line 1880 in styles.css)
Apply inline rules to 'row' (NOT TO THE ROW RULE) on line 230 in the source so it looks like the following:
<div class="main-content">
<div class="row" style="
padding: 65px;
background: url(http://frenchegg.com/images/gray.png) no-repeat;
background-size: 85% 100%; background-position: center;">
The rules are as follows for copying purposes.
padding: 65px;
background: url(http://frenchegg.com/images/gray.png) no-repeat;
background-size: 85% 100%;
background-position: center;
Note the padding is a bit screwy, but it's simply to show you where your background needs to be to respond correctly.

browser does not fill the background properly with repeat-x

in the header menu i am using an image with repeat-x property. it works perfectly in full screen however in low resolution i.e in 1024X768 and 800X600 screen it leaves some margin. it leaves the margin when a horizontal scroll takes place. how do i make sure even if horizontal scroll exist the repeat-x property should cover the area of the scroll. is there any css property for this?
the css for this i am using is.
#header {
height: 111px;
background: url('../img/header-bg.jpg') repeat-x;
width: 100%;
}
let me know if you want more code ill host it in jsfiddle. thank you.
i have hosted my site in http://iarmar.com/test/bn just in case you want to test.
Set min-width: 1040px; to your #header
As expalined in my comment (and by Jeaffrey), set your #header with a min-width or use 100%.
See this www.viralment.com oh its says 30 at least
try using these:
background-image: url("gradient_bg.png");
background-repeat: repeat-x;
