Why :-moz-full-screen-ancestor necessary in firefox to display perfect result?
All of the other browsers are working very well without this code.
#skinn:-moz-full-screen-ancestor {
bottom: 0;
left: 0;
position: absolute;
width: 100%;
}

These are called vendor-specific prefixes and they are used by developers to enhance features and add nice touches to objects.
They (-moz prefixes) were initially developed by Gecko when they couldn't fully support the use of the full-screen attribute, and other attributes like them. So they made a work-around version which you have used above.
Here's a webpage which i came across that might help you: http://davidwalsh.name/moz-css
Here's the pickle. To resize checkboxes in html, it is usually recommended that you utilize js to force the browser to resize the elements.
However, in our case, we are using wkhtmltopdf (a command line converter that utilizes webkit to create the html output that is then converted into PDF,) which to my knowledge, does not execute js.
In this context we still need to shrink down some checkboxes and radio buttons (actually, 'some' is wrong - a whole heck of a lot of them!)
What is a possible method for doing this, and if there is more than one, the best practice?
I know this is pretty old thread, but I had the same problem and did not find a proper answer anywhere so I wanted to help other people with similar problem. I was dealing with size of checkboxes in generated pdf by mdpf. Only thing that worked was font-size. Try something like:
<input type='checkbox' style='font-size: 20pt;'>
Hope this helps somebody.
Have you tried to set a print stylesheet to see if it affects the output?
#media print { /* css code */ }
Have you tried using CSS to change their size? This works fine in Chrome which is a webkit based browser.
input.big{
height: 2em;
width: 2em;
}
input.small{
height: 0.5em;
width: 0.5em;
}
<input type="checkbox" id="small" class="small"/><label for="small">Small</label>
<input type="checkbox" id="big" class="big"/><label for="big">Big</label>

I am making a HTML/CSS and jQuery-based file manager aimed at mobile devices. Part of it involves the use of CSS=based modal dialog boxes for various file operations (copy, delete etc.).
I achieve the modal dialog behaviour like this:
<div id="overlay">
<div id="modalBoxControls">[close]</div>
<div id="modalBox">
<div id="modalBoxContent"></div>
</div>
</div>
And the CSS is:
#overlay {
position: fixed;
left: 0px;
top: 0px;
width:100%;
height:100%;
text-align:center;
z-index: 1000;
background: ([semi-transparent png]);
display: none;
}
#modalBox {
width: 80%;
background-color: #fff;
margin: 0px auto;
opacity: 1;
}
I use jQuery to show and hide it by calling .fadeIn() and .fadeOut() on the overlay element.
So far so good - this works great in all the browsers on my dev machine.
However, when testing on my WP7 (Samsung Omnia 7), a rather bizarre thing happens. The modal dialog shows up fine, the page behind it is blacked out. But clicks (or taps) go through the #overlay and activate anything behind it, even though it totally covers up everything behind and it's z-index is 1000.
I also tested this with the well-known "Lightview" plugin from Nick Stakenburg (a well-tested and refined piece of code) and found the same behaviour on IE on WP7.
So it seems like this could be a bug with the browser itself.
Does anyone know any solution for this?
Edit - jsFiddle with example of problem
So, check this out in your WP7 device and see how the files can still be clicked even when there is an overlay over the top of them: http://jsfiddle.net/michaelbromley/CHU76/
If by "activate anything behind it" means input controls like text input then I had the same issue. To be honesty I don't know a good solution. My workaround was disabling input controls during popup is showed and then activating them back by removing disabled attribute. The problem seems not to be related to jqmobile, but supposed to be a general behavior.
OK, so it seems that there may be no "proper" solution to this problem (hey, 24 hours is a long time on SO!), so I have come up with my own hack solution:
I when the modal dialog box is opened, I simultaneously set the "visibility" CSS property of all the elements "behind" the overlay (i.e. links and anything else that would otherwise erroneously respond to taps/clicks) to "hidden" (by using jQuery's .css() function). This means that the page layout is not affected, and that there is now nothing there to be clicked on.
As I said, this is a bit of a hack and will not be suitable for everyone who runs into this problem. However, it works well for me.

Yes, this is clearly a bug in Window Phone 7 and it is not even fixed in Windows Phone 10.
I will report this bug to Microsoft and hopefully it will be fixed.
I need image to stretch as background of page. It doesn't matter if page will not scale well, what ever screen resolution may be, whole image has to be visible on screen. I found some solutions on Google, but it either didn't work in Firefox2 or IE6 or both, and I need those two too.
I hate when people don't upgrade their software, but I'm still see these browsers in google analytics data hitting web page, especially IE6.
Is there good cross browser solution for this?
You could use a good old fashioned img tag, without height and width attributes. In your CSS, position it absolutely with a low z-index, set height and width to "100%".
Put everything else on the page in another div with a higher z-index
Like this:
<style type="text/css">
#stretchy {
postion: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
z-index: 0;
}
#everything_else {
position: relative;
top: 0;
left: 0;
z-index: 10;
}
</style>
...
<img src="/images/myimage.jpg" id="stretchy" />
<div id="everything_else">
...
</div>
See http://axoplasm.com/lost.html for an example.
It's not exactly a "background image" (and probably not W3C standards-compliant CSS) but it works.
I don't want to hijack this question, but if you had this code:
background-image: url('images/background.gif');
background-size: 100%;
This repeats the image in all current browsers (IE, FF, GC, SF, OP) which while unsavory works across all the browsers, unlike the z-index depth method (I have a complex foreground).
However if a browser was to suddenly get bg-size CSS3 support, does the CSS3 spec say what should happen? Should it stretch the image or do what it always did and repeat?
It is not possible in CSS1 or CSS2, however it is possible in CSS3: requiem4adream.wordpress.com/2006/09/29/css-stretch-background-image/
However this is not available to IE6.
An alternative would be using background-repeat, or this site has something that might work (I havent checked if it works): webdesign.about.com/od/css3/f/blfaqbgsize.htm
I know what you mean about users not upgrading browsers, but at what point do you stop coding for IE5, or even IE4?
Good luck,
Matt
A good alternative would be to use a "static image" that fades out to a pattern or solid color. That way you still get your background image (however big you want it) and scalability.
In CSS3, you can use background-size: 100%;
Firefox 3.5 supports some CSS3 properties, but I don't believe they support EVERYTHING yet... (I think).
How can I hide the div without using display:none or JavaScript?
In my country, a lot of Blackberrys come with the CSS support disabled (the mobile companies here are not so good to developers). I have text that says
<div class="BBwarn">
please activate your css support and a link
</div>
I want to hide that once the user activates CSS support, but i can't use display:none; because it is only supported in BB firmware 4.6. It is a public site and I can't make all my visitors upgrade.
Does anybody knows a solution to this? I hope the question is easier to understand now.
Update:
Thank you all for the answers but I can't use
position:absolute
overflow
because they are available from Blackberry firmware 4.6 and up
things to try:
use the z-index to put it behind some other element
move it off the screen by absolute positioning
visbility: hidden
make the content "invisible" by setting background to foreground color (works only for text)
opacity: 0
but the real question is: why?
This is a common way:
margin-left: -9999;
How about:
visibility: hidden;
That should hide the DIV, (note how it will still be rendered but be invisible, that means it will take space in the document as if it was visible, but be invisible (unlike display:none; where the div will not be rendered)).
<div style="height:0;width:0;overflow:hidden;">
<!-- content here -->
</div>
Incidentally, this is what I do to preload images, which is nice because it doesn't use javascript.
Visibility:hidden won't do the same thing because some browsers are smart and won't make the request unless it thinks its actually visible.
Why not try the simple:
position: absolute;
left: -1000px;
I can't see why it wouldn't work.
I'm not sure of the percentages you're talking about that are using < 4.6, but if it's that important to you, then I can see a rationale for accepting that you can't please all the people all the time, and an acceptable cascading solution to this should be achievable. Probably with a link to explain the benefits of upgrading and enabling css.
height: 0;
overflow: hidden;
visibility: hidden;
color: #fff;
background: #fff;
BTW - you'd better make sure that you're css is good if you're telling someone to turn it on... :-)
What makes you think display: none is not supported before version 4.6? Did you test that, or are you going by their documentation?
I'm not a mobile developer either, so I'm just going by what I gleaned from the documentation.
The BlackBerry Browser 4.6 CSS Reference indeed mentions "Availability: BlackBerry® Device Software version 4.6 or later" for the display property, but their BlackBerry Browser 4.3 Content Developer Guide indicates that 4.3 already supported a very limited version of the display property, including display: none. Versions before 4.3 don't support the display property (again, going by the BlackBerry Browser developer documentation).
Can you assume your users do at least have firmware version 4.3, or is that just as unacceptable as assuming they have 4.6?
Have you tried simply setting the width and height to zero? I'm not familiar with the BlackBerry (Browser), but I'm sceptically assuming its CSS support is less than perfect, certainly on the older versions. I wouldn't be surprised if this worked:
.BBwarn {
display: none; /* for 4.6 and up */
width: 0px; /* for 4.3 */
height: 0px;
}
But then width and height are only supported on all elements starting from version 4.3. Before that they could only be applied to <button> and <img> tags and some <input> types (according to the documentation).
So perhaps the safest way to really make it work on all BlackBerry firmware versions is to use an image for the warning, and use CSS to set its width and height to zero.
If an image is not an option (due to lozalization issues or so, perhaps), an ugly hack might be to specify an empty/illegal image source and put the warning text in the alt attribute. I don't know if setting its width and height to zero would still hide that alt text then.
visibility: hidden; will work, but the space taken up by that particular div will still appear. If you are going to use the negative left-margin method, remember that you will need to set the object's position to absolute.
How about this:
clip: rect(0,0,0,0);
Note: Please note the clip property does not work if "overflow:visible" is used.
In your case:
<div class="BBwarn">
please activate your css support and a link
</div>
just add this css:
.BBwarn{
position: absolute;
clip: rect(0,0,0,0);
}
You could position it absolutely off the screen.
But I, also, am not a mobile developer.
I assume You don't want to use JavaScript because the Blackberrys don't support it.
What about if you did the opposite and displayed the block of code with JavaScript, rather than tried to hide it?
<script type="text/javascript"><!--
document.open();
document.writeln('<div class="BBwarn">');
document.writeln('please activate your css support and a link');
document.writeln('</div>');
document.close();
//--></script>
This is a bit of a hack, but would not display the text with disabled JavaScript...
You can do something like wise:
.class{
opacity:0; overflow:hidden; visibility: hidden; height:0;
}
for being more precise you can add :
color:transparent; background-color:transparent;
What exactly is wrong with (the earlier mentioned)
width: 0
height:0
visibility: hidden
width: 0 height:0 visibility: hidden
...Does not always work with firmware 2.2 and older. Sometimes you can get an element to be hidden, but it will reappear with certain keystrokes (like underscore, for instance).
Or you could use Please enable Javascript
And use an image that reads "Enable CSS" and style it using "display:none".
So that whenever the corresponding feature is enabled these warnings wont show.
Alternately, I presume you are using some server side code? You could try detecting for the most common known platforms that support specific versions of css/javascript and deliver content accordingly. You might not even have to write it all yourself.
I had a similar problem when I was trying to customize a select box using javascript in BlackBerry Curve 8530 (OS 5.0). But, the menu created couldn't be hidden because the css following properties still don't work:
display
overflow
position: absolute
visibility
z-index
And destroying and recreating the HTML elements didn't work either, so I got here and could solve my problem.
I know my answer isn't exactly about the question raised here, but once I got here when had problems, I think I'm not the only one with it happened and is going to.
Anyway, even if those css properties worked, what I needed was some code that could work on the most of the BB models.
My solution was made using all the answers found here. It was simple. I made two classes:
.element
{
width: 100px;
height: 100px;
font-size: 12px;
color: black;
background-color: transparent;
border: 1px solid black;
}
.element_hidden
{
width: 0px;
height: 0px;
font-size: 0px;
color: white;
background-color: white;
border: none;
}
Yes. I've made two of them for each kind of element I had in my page.
Initially, all classes are set to class="element_hidden", so when the mouse is over the select box menu, all the classes are changed to class="element" and they are shown and hidden as if they were made invisible/visible.
I hope this can be useful to someone! ;D
We can use the transform property to scale the element along the x and y axis.
. BBwarn{
transform : scale(0,0);
}
I used font size to obtain this without using display none
font-size: 0px;
As you said in question that you need solution for Blackberry version below 4.6 and there are very few CSS properties supported for Blackberry version below 4.6 so we can use some sort of hack for this purpose. Try and set the text color to whatever the background is or set font-size to 0. It's a hack, but it makes it invisible. Run the following snippet and let me know if its works for you.
.alert1 {
color: #fff; //3.8 or later
}
.alert2 {
font-size: 0; //3.8 or later
}
<b>Alert1</b>
<div class="alert1">
please activate your css support and a link
</div>
<b>Alert2</b>
<div class="alert2">
please activate your css support and a link
</div>
