IE7\8 Doesn't Play Well with Sprites On inputs? - asp.net

I'm using the css sprite technique to hold all the buttons on the site in one PNG Image.
This technique works fine on all browsers on your normal Style Buttons, however for IE 7/8 it shows a border and a red x on any input where I use a css class to define the image. This technique works fine for Firefox.
Am I missing something here ?

The "red X" occurs because there is no SRC (or an invalid/not-available resource specified in the SRC) for the IMG element.
You can use a transparent "stub" image to fix that issue. Also, make sure to set BORDER=0 on the IMG as well (guess why :-).

Please try to change the background part from CSS code:
background: url('XXXXXXXX.png') no-repeat
I think it is a CSS parsing problem

CSS to avoid the image alt text getting displayed in print preview

In IE 8, I am seeing the alt text getting displayed in the print preview when the image is not getting displayed.The issue is not occurring in chrome. I want to fix this issue in IE 8.
Src of the image gets added in run time. At some times images will not be available from the server
<img src="null" alt="weird issue">
Needed a fix without using javascript
You can't style the alt text directly, but it will inherit from the img parent so probably the easiest is to simply set the color of your img to white in the CSS (and if for print applications, then within your print styles).
Try this:
img{
color: #fff;
background-color: #fff;
}
In that example, I've also set the background-color to white but this probably isn't 100% necessary given that if this is a print style, the background will inevitably be white anyway.
As has been mentioned in the comments below this answer, you may be able to use a CSS attribute selector to only target those imgs that have 'null' as their source.
This would work like this:
img[src="null"]{
color: #fff;
background-color: #fff;
}
This would, however, come with a few additional requirements/assumptions:
That the src is indeed 'null', and not just an ampty string (in which case you could use img[src=""]).
CSS attribute selectors work in IE7 and up. However, IE7 and IE8 are a little delicate to !DOCTYPE declarations so you have to ensure that your page has a valid !DOCTYPE declared.
Older browsers (IE6, for example) will not support this, so you'll still get the alt text come through.
Assumes that a CSS resolution is actually what you're asking for, and - as before - that the background the image sits on is indeed white!
You could extend upon ths use of attribute selectors to simply ensure that those images coming through with src="null" aren't displayed at all:
img[src="null"]{
display: none;
}
For mozilla : study this code and find a way to achieve it with other browsers.
img:-moz-broken:before,
input:-moz-broken:before,
img:-moz-user-disabled:before,
input:-moz-user-disabled:before,
img:-moz-loading:before,
input:-moz-loading:before,
applet:-moz-empty-except-children-with-localname(param):-moz-broken:before,
applet:-moz-empty-except-children-with-localname(param):-moz-user-disabled:before {
content: -moz-alt-content !important;
unicode-bidi: -moz-isolate;
}
Or, some absolutely basic inline javascript, some verry ugly old-school inline event handler:
<img src="broken.png" onerror="this.style.display='none'" />

Cursor Image using CSS

I would like to use an image that is 195 x 29 to replace the hand when someone hovers over a map image. I'm trying to do this css but would consider a javascript option if no css option is available. I've tried several different css options but can not get the results I'm looking for. Currently i have my css code setup as:
#docmap {float:left;width:620px;height:225px;}
.click a:hover {cursor:url(images/click.png) no-repeat !important;}
and my html is:
<div id="docmap" class="click"><img src="http://whistlerworks.com/clients/918smile/site/wp-content/themes/Karma/images/map.png" alt="" /></div>
Thanks for the help.
.click a {cursor: url(images/click.png), pointer}
https://developer.mozilla.org/en-US/docs/CSS/cursor/url
check this out, might help let me know if its useful
http://www.htmlgoodies.com/beyond/css/create-custom-cursors-with-javascript-and-css3.html#fbid=2P5qQIHDj3T
The safest image format is a 32x32 8-bit black and white .ico file.
As #isherwood mentioned, the basic syntax is:
.click a {
cursor: url(my-icon.ico), auto;
}
I don't think JavaScript would help. Any browser support available would likely be via CSS alone. And you'd have to be willing to live with some browsers simply not supporting it (i.e., progressive enhancement).
Testing in different browsers
Here's a demo that uses a variety of image formats. Move the mouse over the squares to find out what works in each browser. In each case, if it works, you'll see a butterfly cursor.
Exceptions: The bottom row uses a completely-transparent image, so you should see no cursor at all. On the first two rows, in the "Help" column, you should see the default help icon (which is the fallback cursor for all of the other squares).

declaring background property in css twice

I am reverse engineering a previous employee's work and noticed a number of css classes look like this...
.img-shadow {
float:left;
background: url(../images/shadowAlpha.png) no-repeat bottom right !important;
background: url(../images/shadow.gif) no-repeat bottom right;
}
Can anybody think of a reason for a css class to declare background twice like this (specifically with the !important)?
According to wikipedia, the second background rule is for IE6.
Internet Explorer 6 and below also
have a problem with !important
declarations when the same property of
the same element has another value
specified within the same code block,
without another !important
declaration. This should result in the
second value being overridden by the
first, but IE6 and lower do not honor
this.
It's a cheap PNG fix for IE6. Since IE6 won't recognize the !important tag, it will use the GIF background, while all other browsers will use the PNG.
Older versions of IE will use the last one.
These versions had problems with png transparency.
looks like he's attempting to support browsers that don't handle alpha .png's properly (cough IE6 cough)

What is the standard way to add an icon to a link with CSS?

I'm used to use padding + background-image to place an icon next to a link.
There are many example of this approach. Here is one from here:
<a class="external" href="http://www.othersite.com/">link</a>
a.external {
padding-right: 15px;
background: transparent url(images/external-link-icon.gif) no-repeat top right;
}
But most browser don't print background image, which is annoying.
What is the standard to place icon next to links which is semantically correct and works in all cases?
EDIT
What about CSS :before and :after? Is it a recommended practice?
a.test:after {
padding-right: 5px;
content: url(../pix/logo_ppk.gif);
}
I'd personally pad it and put a background image via a CSS class (just like your example). It's by far the lightest route, it keeps the document light and semantic.
If printing them really matters (and I do mean really matters) stick a real image in there but be aware that it does screw up markup from a semantic aspect.
Perhaps a better compromise solution would be to have a "printable version" which uses images instead (either by something server-size or some JS that replaces the CSS class with an actual image.
Although as OLi saying keep icon in css is best method and there is no way to print css backgrounds. (until you turned on css background printing from browser settings).
but if you can use javascript then this method will work for you
http://www.learningjquery.com/2008/08/quick-tip-dynamically-add-an-icon-for-external-links
you can add inline image to link.

Background image is not displayed in Firefox

An image set as the background of a DIV is displayed in IE, but not in Firefox.
CSS example:
div.something {
background:transparent url(../images/table_column.jpg) repeat scroll 0 0;
}
(The issue is described in many places but haven't seen any conclusive explanation or fix.)
Sorry this got huge, but it covers two possibilities that consistently happen to me.
Possibility 1
You may find the path to the CSS file isn't correct. For example:
Say I have the following file structure:
public/
css/
global.css
images/
background.jpg
something/
index.html
index.html
On public/index.html the following paths will include the CSS file:
#1: <link href="./css/global.css"
#2: <link href="/css/global.css"
#3: <link href="css/global.css"
However on public/something/index.html number 1 and 3 will fail. If you are using a directory structure like this (or an MVC structure e.g.: http://localhost/controller/action/params) use the second href type.
Firebug's Net monitor tab will tell you if the CSS file can't be included.
On the subject of paths remember that images are relative to the path of the CSS file. So:
url('./images/background.jpg') /* won't work */
url('../images/background.jpg') /* works: ../ == up one level */
Hover over the url() part of the background attribute in Firebug's CSS tab to check if the file's being loaded.
Possibility 2
It could be that the div has no content and thus has a 0 height. Make sure the div has at least a line of something in (e.g.: lorem ipsum delors secorum) or:
div.something {
display: block; /* for verification */
min-height: 50px;
min-width: 50px;
}
Check Firebug's layout tab (of the HTML tab) to check the div has a height/width.
Strangely enough, after smashing my head on the keyboard for hours, I added display:table; to the DIV's style and the background image magically appeared in FF.
It looks like a background-attachment issue. It needs to be set to fixed (not scroll) to work in FF.
See: http://www.w3schools.com/cssref/tryit.asp?filename=trycss_background-position
Happend with me. The jpg does shows in IE but not in Firefox or Chrome. Here is the solution
Change the following css for the element where image is displayed. It can be span, div or any other element :
display:block
Old post but I just Had a similar problem images not showing up in Firefox turns out it was Ad-block add-on, had to change the names of my images
Try putting the image name in quotes, e.g.:
background-image: url('image.jpg');
I've had a similar issue. The reason is that firefox is sensitive for missing fields in your css. Chrome will (sometimes) auto complete missing field, thus the issue appears on your firefox browser.
You need to add a display type, because right now it is being translated to 0 height.
In my case:
.left-bg-image {
display: block; // add this line
background-image: url('../images/profile.jpeg');
background-repeat: no-repeat;
background-size: cover;
background-position: center center;
opacity: .6;
min-width: 100%;
min-height: 100vh;
}
Make sure that the image you are referring to is relative to the css file and not the html file.
try this.
background-color: transparent;
background-image: url("/path/to/image/file.jpg");
background-repeat: repeat;
background-position: top;
background-attachment: scroll;
Instead of using URLs relative to the page/stylesheet, a cross-browser solution is to give a relative URL starting with the application/domain root.
/* Relative to Stylesheet (Works in Firefox) */
background: url('../images/logo.gif');
/* Relative to Page (Works in IE, Chrome etc.) */
background: url('images/logo.gif');
/* Absolute path (Fine, unless you change domains)*/
background: url('http://www.webby.com/myproduct/images/factsheet.gif');
/* Domain Root-relative path (Works in Firefox, IE, Chrome and Opera) */
background: url('/myproduct/images/factsheet.gif');
FYI: As far as I'm concerned, there is no requirement to use quotes in CSS URLs, I've used them here 'cause it looks prettier.
I solved a similar problem by renaming the CSS class. MSIE allows CSS class IDs to begin with numbers; Firefox doesn't. I had created a class using the width of the image in pixels e.g. .1594px-01a
I actually knew it was non-standard syntax but since it was working fine in MSIE I had forgotten about it. After trying all the other stuff it finally dawned on me that it could be a simple as the naming, and as soon as I put a letter in front of the class, presto!
For me, it was a matter of the file-name being case-sensitive. I'm not sure if it was CSS or if it was my Ubuntu operating system, or if it was firefox, but the way that I finally got the background images to display was by referring to BlueGrad.jpg instead of bluegrad.jpg. The former of the two is how it was saved. I didn't think it would be case sensitive, but it was.
You could try this:
div.something {
background: transparent url(../images/table_column.jpg);
}
The other declarations are shorthand CSS properties, and I afaik they are not needed.
Do you have this online somewhere? I'd like to see if I can fiddle with it a bit. (locally)
More questions than answers I'm afraid, but they might help you get to the right answer:
Is it possible that you are collapsing the div in Firefox in some way (with some floats or similar)?
Is there any other content in the div to ensure it's large enough to display the image?
Have you installed Firebug and taken a look at the CSS definitions on the page?
Are you absolutely sure the image is a JPG file and not a PNG/Other file?
I'm wondering if IE is letting you get away with something other browsers are not.
Likewise, is the files case exactly as specified?
There's this HTML 'base' tag like in
<head>
<base href="http://example.com/some/bizarre/directory"/>
</head>
If this is present in your page, the image for the url is not relative to your current url, but to the given base url. I wouldn't know why IE displays it and Firefox doesn't, though.
The Webdeveloper Firefox extension provides the option to "Display broken images" - this may come in handy. Also, you might try "Live Http Headers" to see if/what image is requested and what the return code is.
I had a similar problem regarding the CSS background-image property in FF. It worked fine in IE but refused to work in FF ;) After reading a few posts I established that the issue was indeed that there was no content in the div except for a table (I was trying to make the background image adjust to the size of the broswer without collapsing or expanding and therefore used a much larger image in the background of the div in order to form a 'cropping' of sorts.) The solution for me it seems was to simply 'cheat' by placing an img tag that displayed a blank .png file that I then re-adjusted to the the correct height of the image with width set to 100%. This worked for my problem, and I hope it helps anyone else who is running into a similar problem. Probably not the best fix, but it's a fix ;)
The only other thing I can think of besides what has already been said is the way the picture was created. If you made/edited the image in Photoshop, make sure you save as Save For Web...
Sometimes if you use a JPG image for Photoshop without saving as a Web image, it may not appear in Firefox. I had that happen a few weeks ago where a graphic artist created a beautiful header for a mini site and it would NOT appear in FF!
Wait...
Try setting a width and height on the div to expand it. It may be a no-content issue in your div.
For those, who encounter the problem in FF, but not in Chrome:
You could mistakenly mix between different value types for the position.
For example,
background: transparent url("/my/image.png") right 60% no-repeat;
Will make this error. The fix could be:
background: transparent url("/my/image.png") 100% 60% no-repeat;
My mistake was to use '\' instead of '/'. Worked OK in IE, but not in other browsers.
I found two things that were causing this problem:
I was using a .tif file which Firefox did not seem to like - I changed to a .png file.
I added overflow:auto; to the CSS for the div - display:block; did not work for me.
It may look very weird, but this works for me >
#hwrap {
background-color: #d5b75a;
background: url("..//design/bg_header_daddy.png"), url("..//design/nasty_fabric.png");
background-position: 50% 50%, top left;
background-origin: border-box, border-box;
background-repeat: no-repeat, repeat;
}
Yes, a double dot and double slash ... ??!!?? ... I can't find anything on the internet that reports this strange behaviour.
[edit]
I've made a seperate post > https://stackoverflow.com/q/18342019/529802
(It doesn't seem like these are the exact circumstances as of the OP but the issue is somewhat related and I've found a workaround for that which I want to share)
I've had the same problem – background-image visible everywhere except in Firefox – and for me, the issue had to do with the fact that I'm working on a browser add-on.
I'm injecting a file style.css in the pageMod module with the contentStyleFile attribute. In it, there's the rule background-image: url(/img/editlist.png); where I'm referencing an image file external to the add-on. The problem here is that Firefox, unlike other browsers, misinterprets this external domain root as the add-on's internal root!
The css-file is a 1:1 port from the Chrome version of the extension/add-on, so I didn't want to mess around with it. That's why I've added an additional contentStyle rule in combination with a copy of that image in my resource folder. This rule simply overwrites the rule inside the css-file.
(In hindsight maybe even a more elegant method than before …)
Nobody mentioned background-origin so there you go :
background-image:url('dead.beef');
background-size: 100% 100%;
background-origin:border-box;
Solved the problem for me ; my background apparently was outside my div.
In my case it caused by "Strict" mode in FF Privacy & Security settings. After I have changed to "Standard" all background images had become visible.
This worked for me:
1) Click on the background image table.
2) Right click on the status bar at the bottom of the page.
3) Click Inline styles.
4) Click the Background styles tab.
5) If you see 'Transparent' in the colour title, that is the problem.
6) Click the colour box and select a colour (white is a good choice.)
7) The colour title should now read white.
8) Click OK.
9) Save the page.
10) Upload the page and overwrite the existing file.
11) Refresh the page and your background picture will display.
Note: Please ensure that you have uploaded your background picture jpeg. I forgot to upload the background jpeg once and spent ages trying to sort it before I realised my error.

Martin
