Many coders embrace sprites but they seem to forget that sprites require more-less fixed containers. You cannot use srite on h2 if you cannot control it's height. H2 looks good when you have 1 (2) rows of text, but hell breaks loose when you have 3 rows -- next image from the sprite becomes visible.
Whats the best solution to fix it? Icon inside it's container?
<h2>
<span class="ico">Text that needs to be hidden</span>
Lorem ipsum<br />dolor sit<br />amet
</h2>
Another solution is to place images on sprite file diagonally, but this solution doesn't allow 100% 0 positioning.
What's your solution?
Note the positioning of the red section in the images below
If neither the width nor the height is variable, place the image
anywhere in the sprite.
If the height is variable but the width is fixed, you can try placing the background along the left or right edge of the sprite. This will allow you to repeat-y.
If the width is variable but the height is fixed, you can try placing the background along the top or bottom edge of the sprite. This will allow you to repeat-x.
If both the width and height are variable, I don't believe you can use an image in the sprite effectively. You should just use a standard background image.

I hope what I try is not impossible.
Let me explain first: I have a responsive design which requires a background to be fixed under some situations (media query blocks). The design in question is this one:
http://think-open.at/fileadmin/templates/responsive/content.html
Basically there are two media queries: one for the maximal height and one for the minimal width. If there is enough viewport height there is a scrollbar in the content area and the design height is fixed. But if the viewport is not large enough for showing the predefined height the height-mediaquery removes the scrollbar from the inner div so there won't be two nested scrolling containers (body + div) and sets the content area to height: auto.
There is also a responsive media query if the viewport is too narrow but this works flawless.
Now the problem: When the design switches to the mode where the whole page scrolls (below 830px height) I would like to position the image in the right container "fixed" so it does not scroll out of the viewport. But then the problem arises, that I can't really position the background in regards to the container div as "fixed" positions an background image in regard to the viewport. I have created a CSS fiddle here:
http://dabblet.com/gist/ae5c3598e1465ce0c90e
If you change the width you notice the problem. I would like to have the right border of the image aligned with the right border of the green box.
Is this somehow possible? I have no problem using calc() as there will be a condition in my CMS to use the plain old-school design if an older browser gets detected.
I solved it myself now. Sorry for posting.
The trick was: As my design is centered, I started to try using calc(50% + somepixelvalue). This did the job.
I adjusted the CSS playground:
http://dabblet.com/gist/5b63553f47a81f3bb701
Now the image is always up in line with the right border of the green area. When scaling there is sometimes a 1pixel difference but this doesn't matter as the background will get assigned to some container element which acts as mask.
Is the background-position css property used to indicated where in the element should the image be displayed (like this) or what part of the image should be displayed (like when using sprites) ?
In my instance i have a div of let's say 300px width, i want the image to be shown in the right part of that element so normally i just added a center right to my background declaration, though now my image is a spirit so how can i control the coordinate of the image that i want to display ?
Seems to me that this background property act in 2 different way.. Am i missing something ?
If the place where you want to put element of the sprite is larger then the element then you need to put white space (trasnparent) around it. And you can't use keywords like center, you need to use pixels, because you will center whole sprite and not your element.
Using sprites is like using window where background is larger then background image so you need to position the window (actually you position the background).
If your container is larger than the background sprite image part you want to display then the other part of image will also be displayed. Better use Sprite cow to generate sprite it will give you the css for different parts of sprite image

I need to create this layout and I'd like to do as much of it as possible with CSS, rather than using images and whatever.
As such, how can I do this in CSS? (if at all?)
As you can see, there is the image behind, with the button overlaid with padding. The bit that I'm struggling with is creating the curves on the IMAGE above and to the left of the button and bottom to the right of the button (I've pointed them out on the pic below).
Any help would be great.
Thanks
I know just enough CSS to be dangerous so I can't detail every step, but I think you can approach it like this:
Split the background image into two separate images both at a z-index of 0 at the height of the top of the grey box. I think you can use two div's that reference the same original image with different offsets (similar to CSS Sprites) but I don't know the details of how to do that. The left edge of the lower div would start where the grey box ends. Round the lower-left corner of each "image" div.
Add the grey box at a z-index of 1 with appropriate rounding, and then the blue box at a z-index of 2, again with appropriate rounding.
The background of the block element containing all of this would also have to be grey to match the grey border and properly fill in grey where your right-most arrow is pointing.
You don't have to split your image at all, only the container divs.
Let me detail a bit:
You can have your image set as a background image instead of putting it in a src attribute of an img tag. This technique is most commonly used when working with CSS sprites.
So, if you have you uppermost div at a constant width and height, if you try to apply the background image in it, you'll see it fits very nice.
On the bottom, you have two divs or whatever block element you'll like, just be sure to put fixed width and height, so the background will be applied and you will be able to actually see it.
Then all you have to do is fiddle with css background-position to adjust the SE chunk of image.
I'll be putting a small demo together to better illustrate the idea.
After you have a big div at the top, and two smaller at the bottom, where two of them share the same background-image, but with different background-position, you can safely add some css3 border-radius to fit your roundness needs. You can also use some tool like http://css3generator.com/ to add a compatibility layer on all browsers with ease.
That is very easy to realize with pure css. The page you have shown is divided into 3 divs without any margin. You only need to set the right border radius for each div.
This is a function of the background image, which is a css element if that's what you mean, but it is not a seperate attribute for a selector, at least not in standard CSS. Wait until CSS3 becomes more prevelant, then it's corner-radius or some such thing.
Well it's 3 probably 3 seperate divs, a hole "burned" into the background image, or a div being overlayed for the button.
The best way to figure out how it's done is to read the source of the page you found it on.
For convenience:
If you have a webkit based browser like chrome or safari then enable developper mode mouse over the button "right click" and choose inspect element. Otherwise you can pour over the page source until you find what you want.
I'm trying to use two divs, one with a non repeating background in the left corner to serve as a 'curved border' image, and the second div, within that one, with a background that is offset by the width of the first div's image so that it seems to be one solid image, that fluidly stretches with the page width. I tried doing this the way I described but it isn't working, only the stretched repeating background div shows up. I would prefer to try from scratch something one of you suggests.
Try setting an explicit widh on the left div, and try using float:left on both (to make sure they align properly).
And set border:none (I'm stating the obvious here, probably).
I have this website.
The div container contains a background with a grungy look, and the body contains another background that is repeated on the x coordinate.
If you view the site you'll see whitespace on the left and right side. I am wondering how I can set the background images to expand based on the screen resolution. Would it work to set a width based on percentage for each div?
To my knowledge, CSS does not support scaling background images, which is disappointing to say the least. Long story short, you'll probably have to fake it with a fixed-position, z-indexed img tag. That, or what you did: a large image with a background-repeat.
I dont see any issues with what you've got in FF3/IE6/IE7 and chrome. only issue i see is the transparent png in ie6 with the ugly gray behind it.
ie6 I gotta fix but what the customer wants is for the with of the page to size up based on the users computer resolution
Unfortunately, you can't scale the image itself.
What you could do would be remake the div structure so that the inner div contains the center of the grungy background and the sides were tiled through two separate divs. You could then recut the center piece to tile both vertically and horizontally and give it a width that is a percentage of the window size. You could keep it from getting too small via javascript.
This is not an optimal solution, but if the client is set on having it scale with the browser window, this might accomplish it for them.
thanks for all your answers, when i said white space i didnt mean actual white space what i was refering to was that the entire container div wasnt sizing (width wise) towards what the users computer resolution was. and since allot of the divs are set with a background image there is no css code for setting the width on the image but i guess it would work on the divs. but thankfully after talking with the customer he changed his mind and doesnt want it anymore :)
