I´ve a litle problem with a website.
jn-racing.de
The "Banner" bar under the navigation in the background is an .png image with gras but the sliding images are in the front of the png.
Z-index of the sliding images are 3 and the css class "banner" are 99.
The background must be in front of the sliding images.
Thanks
The childs of #slider and #slider itself are positioned (relative), which means they belong each to their own stacking context and the z-index will have no effect.
A)
You'll need to remove the position-property. But that might conflict with your positioned images, so that's not really an option.
B)
You'll need the grass-background to reside in the same stacking context as #slider, which means is has to be on an element, which is a direct child of #banner too (a sibling to #slider).
Example:
#slider:after {
content: '';
height: 10px;
width: 1024px;
background: url(images/banner.png) no-repeat left bottom;
}
You should put your grass .png your html under the #slider div and give it (the new img) an ID. As long as it is a background, it will be harder to move it to the front via css. Does that help?

I want to ask about CSS that cause my image stacking each other.
I can't give the fiddle because too many code and css, but I give my web page in here
As You can see there are thumb image for the slideshow, but they stacking each other. I have try to use margin or padding for the img, but nothing happened, except if I change the size of image to 100, it will run nomrally. I've try to change position to absolute, relative, etc, but the image being worst, full stacking.
So what must I do to create this image not stacking each other?
Sorry for my bad English.
From what I can see, you are setting each parent element to have a width of 69px, whilst each child image is 180px wide. This will cause overlapping, as the size of the image does not affect it's parent size.
applying these rule fixed the problem for me:
.es-carousel ul{
width: auto;
}
.es-carousel ul li {
width: 180px;
}
ensure you remove the 'width:69px' from each li element, too.
I am trying to create a hover over image from a single split PNG
How do I enable it so when the image is not hovered over, the top image will view, but when they hover over, the bottom one will show.
The technique you are asking for is called "CSS-Sprites". Here's a tutorial
It uses the background-position style. For the default state of your element, just set the image as background. Note that you need a fixed height (half the height of your sprite) to hide the second part of the image. You also need a width, because your button will contain no content, just a background. For the hover state, use a negative background-position:
.button-foo{
display: block;
height: 29px;
width: 110px;
background: url("http://i.imgur.com/sJu5vvo.png") no-repeat scroll left top transparent;
}
.button-foo:hover{
background-position: 0 -29px;
}
This means the image is moved up so the top icon in there is above the visible area of your button.
Try to make sprites there is many applications out there. Google Css sprites generator.
Or try this one its free http://csssprites.com. Then its just simple css or jquery if u want any effects.
I actually solved this issue for myself but was wondering if anyone could explain why my fix works. I was styling a popup modal on a mobile site using the MoovWeb SDK and sass. The modal consists of a mask div, which is located immediately inside a container div, and the modal div itself, which was buried more deeply in the DOM.
mask styling:
#modalMask{
opacity: .8;
position: absolute;
display:none;
height:100%;
width: 100%;
z-index:9990;
}
modal styling:
.mw-popup-modal {
top: 80px !important;
left: 0 !important;
position:fixed;
z-index:9999;
display:none;
}
This resulted in the mask sitting on top of the modal and the buttons inside the modal being un-tappable - their tap area was actually located around 3cm below where the button was appearing onscreen on the phone. However, on the desktop version of the site, this styling looked fine.
When I changed the positioning of the modal from "fixed" to "absolute" this fixed the problem, but I'd like to understand why. Do fixed- and absolute-positioned elements each work on their own z-index stack?
Official W3 documentation states
Fixed positioning is a subcategory of absolute positioning. The only difference is that for a fixed positioned box, the containing block is established by the viewport. For continuous media, fixed boxes do not move when the document is scrolled. In this respect, they are similar to fixed background images.
Absolute and Fixed positioning do not work on their own z-index stack context.
I have a background on an div element with position top. Now this background spans across multiple li floats (progress indicator).
div.myListingProgressWrapper{
width: 807px;
height: 39px;
background: url(background.png) top no-repeat;
}
ul.fiveStepProgress li a{
float: left;
}
Now I would like to apply an active state to the a class and move the background of the parent container to bottom as the background contains a different colour and a progress arrow.
My question is, can I move the parent container background to bottom by applying the active class on the child a link?
Cheers
You cannot select a parent from within CSS. There have been several suggestions to the W3C on how to do this over the past few years, but the performance concerns have shot everything down. Plenty of reading on this, here's a link: http://css-tricks.com/7701-parent-selectors-in-css/
You're best off setting the a class on the parent, which affects the child... since you can't do it the other way around without javascript anyway.
I need to place an icon of 48x48 as background. I have this icon in my image sprite where of course there are many other images.
Is there a way to show as background only a porition of the image?
thanks
EDIT: Is there a way to do this without setting width-height of the backgrounded element? (I am not sure if acutally i can set a width-height)
Edit2: this is what i need: http://jsfiddle.net/pdxnj/
Thanks
Set the width and height of the element to 48px.
.element{
width: 48px;
height: 48px;
}
Set the background of the element to your image
.element{
background-image: url('image.png');
}
Move the background so that the top left corner of the icon is positioned correctly.
.element{
background-position: 20px 94px;
}
The two numbers in background-position are the X and Y coordinates (respectively) where the top left corner of your 48px by 48px is in your sprite image. So maybe it's actually 96px 0px or something.
EDIT
If you can't control the width and height of the element you are trying to put the background in, but you can add new DOM elements, you can try adding a span inside the element you really want to put the image as a background for.
It would look something like:
<div id="noControl">
<span id="justCreated">
</span>
</div>
and the CSS would look exactly the same as above, except you would need to treat the inline span as a block element:
#justCreated{
display: inline-block;
}
EDIT 2
If you have control over new DOM elements, and want to make your sprite the background without messing with a span, just add another div inside your original one.
Would wind up looking like:
<div id="noControl">
<div id="justCreated">
ALL of the content that used to be inside #noControl
</div>
</div>
and the CSS for it would be
#justCreated{
width: 48px;
height: 48px;
background-image: url('image.png');
background-position: 96px 0px;
z-index: -200;
/* z-index of all the contents needs to be not set, or set to larger than -200 */
}
This is all theoretical, but it SHOULD work.
This way, you can apply the sprite sizing to a block element without messing with the inline stuff. This may affect CSS if it addresses elements by child status (like #noControl > a), because you are inserting a div between the parent and the child.
I am still researching whether you can do this at all if you have no control over the DOM at all.
simple answer no, but by using html elements you can. Html element hight and width should match the background portion of image.
You can if you're not going to be setting a repeating background. Otherwise no.
To do this, you need to play around with the background offset, and width/height of the actual element that you're setting the background on.
it will depend on how much whitespace is around it in the sprite whether it will fit where you need it to without showing parts of other images.. however you could e.g. put a span where you want the image and crop the span to 48x48 so that it only shows the icon itself. it kind of depends what you want to use it for and how the sprite is built
It's better using ::before or ::after so you can easily define your image size without having overflow problems!
This is possible. You need to display that in a 48x48 div then set position: absolute style for the div and define left and top too for it. Also set z-index: 0 for the div so that it appears under everything.
