css background-position not working

css background-position

Solution 1

I'm not reproducing your issue. Which browser?

Initial thought (without seeing an error case) is to change your initial background definition from a full 'background:' to a background-image declaration:

.button{
  background-image:url(theimage.jpg);
  width;height; etc...
}

By setting background, which is a container for background-position, some browsers may have issues with specificity issues there.

Solution 2

Split up the "background" shorthand property.

If you omit one of the entries in a shorthand property, the omitted entry is reset to the default rather than simply being left alone.

So what's happening is more-or-less the equivalent of this:

#someElement {
    background-position:0 -100px;
    background:url(image.png) no-repeat;
    /* ^--- omitted background-position gets reset to the default */
}

Break the shorthand into different entries:

#someElement {
    background-image:url(image.png);
    background-repeat:no-repeat;
}

EDIT: In your code, the background-position values come after the background values... But I'm pretty sure that the #buttons .button selector is more specific than the #retain-our-firm and similar selectors, meaning that its rule takes precedence over the others even though the others come after.

I know this was asked ages ago, but I think I have the fix.

I had the exact same problem, the positioning was working in Chrome etc but not Firefox.

Took so long to figure out the silly answer,

background-position     :   7 4;

Will work in chrome, but not Firefox..

background-position     :   7px 4px;

Will work in both.

Solution 4

Works if you split up the background properties, http://jsfiddle.net/kTYyU/.

#buttons .button{
    display:block;
    position:relative;
    float:left;
    width:250px;
    height:80px;
    padding-left:20px;
    background-image:url(http://www.websitesforlawyers.us/images/valid_xhtml_code_icon.png);
    background-repeat:no-repeat;
}

I have 3 a tags disguised as "roll over buttons".
```
<div id="buttons">
    <a class='button' id='but1' href=''></a>
    <a class='button' id='but2' href=''></a>
    <a class='button' id='but3' href=''></a>
</div>
```
Each button is getting its initial image from the CSS as follows:
```
.button{
    background:url(theimage.jpg);
    width;height; etc...
}
```
Now, when i try to assign initial background position for each specific element as such:
```
#but1{
    background-position:0 0;
}
#but1:hover{
    background-position:0 -50px;
}

#but2{
    background-position:0 -100px;
}
#but2:hover{
    background-position:0 -150px;
}

#but3{
    background-position:0 -200px;
}
#but3:hover{
    background-position:0 -250px;
}
```
The Issue: each button defaults to position 0 0

Note that the hover positions work as expected.

I'm kind of sick right now so this is probably an oversight but I've been stairing at this for an hour now and can't figure it out.

Any thoughts?

Thanks

Ditto, couldn't find an issue. I'd try ^.

Thanks for the reply. Tried that but no joy. Driving me nuts because I'm not getting any CSS errors reported by the web dev plugin (firefox)

Yeah, you'll have to post an example. I think you'd have an answer within 2 minutes if you did.

This is exactly the specificity issue I was talking about before. Change 'background' in the #buttons .button to 'background-image:url(blah);background-repeat:no repeat' and it works.

Ah ok, IE7 supports :hover, it flounders on :active though, quirksmode.org/css/contents.html#t16.
John Green about 13 years

Yeah, he didn't mention in the original code that he had '#buttons .button'. Changed the face of it entirely. : )

@john, that worked. thanks. as mentioned before, being sick every thing is hazy O.o

Ran into the same issue with chrome. background:URL(image.png) was defined inline on the a tag. It was somehow overriding the a:hover. Changing it to background-image worked perfectly!

For clarification, its the lack of "px" that is breaking it

The regular background:url worked perfectly for me for 2 years. All of a sudden it was broken. Changing it to background-image did the trick!
