If you add one more digit it will go to &lt;code&gt;1e+308&lt;/code&gt;

Found some newer information from 2012:

&quot;Chrome, Opera and IE9 seem to be the only browsers supporting a true infinite value for the z-index, while Firefox is still using 2147483647 and Safari now engages in some strange rounding off behavior after a number exceeds 16 digits in length.&quot;

Is there a maximum / minimum possible value for the CSS `z-index` property? &lt;br/&gt;
Do different browsers have different maximum / minimum accepted values? &lt;br/&gt;
How will browsers handle a high / low value?

I thought I read somewhere once about a max `z-index` value. Maybe I&#39;m wrong. &lt;br/&gt;

Is there a way to delay the :Hover event without using JavaScript? I know there is a way to delay animations, but I haven&#39;t seen anything on delaying the :hover event.

I&#39;m building a son-of-suckerfish like menu. I&#39;d like to simulate what hoverIntent does without adding the extra JS weight. I&#39;d prefer to treat this as a progressive enhancement and not make JS a requirement for using the menu.

Example of menu markup:

    &lt;div&gt;
        &lt;div&gt;
            &lt;ul&gt;
                &lt;li&gt;&lt;a href=&quot;#&quot;&gt;
                    &lt;ul&gt;
                        &lt;li&gt;&lt;/li&gt;
                        &lt;li&gt;&lt;/li&gt;
                    &lt;/ul&gt;
                &lt;/li&gt;
                &lt;li&gt;
                &lt;li&gt;

    div {

       border-bottom:1px solid magenta;
       height:50px;   
    }

**[DEMO][1]**

The div width is 200px so border-bottom is also 200px but what should I do if I want border-bottom only 100px without changing div width?

Shouldn&#39;t the content of my container be cut off when the container has `border-radius`?

## Sample HTML and CSS:

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-css --&gt;

    .progressbar { height: 5px; width: 100px; border-radius: 5px; }
    .buffer { width: 25px; height: 5px; background: #999999; }

&lt;!-- language: lang-html --&gt;

    &lt;div class=&quot;progressbar&quot;&gt;
        &lt;div class=&quot;buffer&quot;&gt;&lt;/div&gt;
    &lt;/div&gt;


&lt;!-- end snippet --&gt;

As you can see I use `border-radius` on the container (`.progressbar`), [but the content (`.buffer`) goes &#39;outside&#39; the container][1]. I&#39;m seeing this on Google Chrome.

[1]:http://jsfiddle.net/u6xkd/

Is this the expected behavior?

P.S. This isn&#39;t about how to fix it, this is about whether it should work like this.

Should border-radius clip the content?

I am just getting started with Bootstrap from Twitter and am wondering what the ‘best practices’ is for customization. I want to develop a system that will take advantage of all the power of a css template (Bootstrap or other), be completely (and easily) modifiable, be sustainable (ie – when the next version of Bootstrap is released from Twitter I don’t have to start over.

For example, I want to add background images to the top navigation. It looks like there are 3 ways to go about this:

1. Modify the .topbar classes in bootstrap.css . I don’t particularly like this because I will have lots of .topbar items and I don’t necessarily want to modify them all the same way.
2. Create new classes with my background images and apply both styles (the new and the bootstrap to my element). This may create style conflicts, which could be avoided by stripping the .topbar class into separate classes and then only using the pieces that are not stepped on by my custom class. Again this requires more work than I think should be necessary and while it is flexible, it won’t allow me to easily update bootstrap.css when Twitter releases the next installment.
3. Use variables in .LESS to achieve the customization. Offhand this seems like a good approach but having not used .LESS I have concerns about compiling css on the client and about code sustainability.

Though I am using Bootstrap, this question can be generalized to any css template.  

Thanks in advance for input.

I&#39;ve been trying to align an image to the center of the table td. It worked with setting margin-left to a specific value but it also increased the size of td too and that isn&#39;t exactly what I wanted



Is there any efficient ways of doing this? I used percentages for the height and witdh of the table.

I have often experienced while developing my web applications that pressing &lt;kbd&gt;F5&lt;/kbd&gt; or refresh doesn&#39;t produce or refresh the proper result. But when we hit &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;F5&lt;/kbd&gt; it generates the correct result. What is the basic difference between simple &lt;kbd&gt;F5&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;F5&lt;/kbd&gt;?

I have often also experienced that pressing simple &lt;kbd&gt;F5&lt;/kbd&gt; and pressing the &lt;kbd&gt;Refresh&lt;/kbd&gt; button in the browser also generate different results.

What is the basic difference among all these requests?

I have tried some solutions but I am unable to get exact name and version:

**I am trying following code:**

    $browserAgent = $_SERVER[&#39;HTTP_USER_AGENT&#39;];
    echo $browserAgent;

**Output of above code:**

    Mozilla/5.0 (X11; Linux i686) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.68 Safari/534.24

**But I am using:**

    Google Chrome 11.0.696.68
    on   
    Ubuntu 10.04

So I can find in `Chrome/11.0.696.68` in output string but it is also showing some other browsers names that is confusing to extract exact browser **name/version** from string.

Why don&#39;t browsers add support for, say, Python scripting as an alternative to Javascript? Or more general purpose scripting languages? Is there a reason that Javascript is the only one implemented across browsers? After all, the script tag does have support to specify the scripting language used.

(I know there is VBScript support in IE, but it seems obsolete for all intents and purposes.)

Why is javascript the only client side scripting language implemented in browsers?

I&#39;m wondering if it&#39;s possible to detect whether a browser is running on iOS, similar to how you can feature detect with Modernizr (although this is obviously device detection rather than feature detection).

Normally I would favour feature detection instead, but I need to find out whether a device is iOS because of the way they handle videos as per this question https://stackoverflow.com/questions/8972726/youtube-api-not-working-with-ipad-iphone-non-flash-device

I have noticed that in Chrome and IE9, for `onmouseout` events there is an `event.toElement` property (so you can determine which element the mouse is now pointing at).

I can not find a comparable property in Firefox.

Unfortunately I can not use jQuery to handle these events, I have to use native js.

Any advice would be appreciated.

I&#39;m looking for a generalized solution for this.

Consider 2 radio type inputs with the same name. When submitted, the one that is checked determines the value that gets sent with the form:

    &lt;input type=&quot;radio&quot; name=&quot;myRadios&quot; onchange=&quot;handleChange1();&quot; value=&quot;1&quot; /&gt;
    &lt;input type=&quot;radio&quot; name=&quot;myRadios&quot; onchange=&quot;handleChange2();&quot; value=&quot;2&quot; /&gt;

The change event does not fire when a radio button is de-selected. So if the radio with `value=&quot;1&quot;` is already selected and the user selects the second, `handleChange1()` does not run. This presents a problem (for me anyway) in that there is no event where I can catch this de-selection.

What I would like is a workaround for the `onChange` event for the checkbox group value or alternatively, an `onCheck` event that detects not only when a radio button is checked but also when it is unchecked.

I&#39;m sure some of you have run into this problem before. What are some workarounds (or ideally what is the right way to handle this)? I just want to catch the change event, access the previously checked radio as well as the newly checked radio.

P.S.  
`onClick` seems like a better (cross-browser) event to indicate when a radio button is checked but it still does not solve the unchecked problem.

I suppose it makes sense why `onChange` for a checkbox type does work in a case like this since it changes the value that it submits when you check or un-check it. I wish the radio buttons behaved more like a SELECT element&#39;s `onChange` but what can you do...

OnChange event handler for radio button (INPUT type=&quot;radio&quot;) doesn&#39;t work as one value

I&#39;m working on a responsive design and I&#39;m thinking of creating navigation icons as .svg files. What is current browser support like and is there a workaround/plugin for older browser versions?

.SVG Browser Support

I created animation in flash and converted it into HTML5 using [Swiffy](http://www.google.com/doubleclick/studio/swiffy/).

I think it&#39;s using SVG to render all of it; is there some JavaScript or a trick to make IE8 and below support it? My animation is working well with Internet Explorer 9.

Thanks!

I am having a hard time  collecting publically available statistics on the percentage of web users that browse with JavaScript disabled.

[Yahoo has published data from 2010][1] and [R. Reid published data from 2009][2] (picked from a site he had access to). 

The findings from Yahoo were rather interesting at that time:

&gt; We took a combination of access logs and beacon data (previously
&gt; included in the page) and filtered out all of the automated requests,
&gt; leaving us with a set of requests we could confirm were sent by actual
&gt; users. This data, which is completely anonymous, gave us a good
&gt; indication of traffic patterns in several countries.
&gt; 
&gt; After crunching the numbers, we found a consistent rate of
&gt; JavaScript-disabled requests hovering around 1% of the actual visitor
&gt; traffic, with the highest rate being roughly 2 percent in the United
&gt; States and the lowest being roughly 0.25 percent in Brazil. All of the
&gt; other countries tested showed numbers very close to 1.3 percent.
&gt; 
&gt; ![Yahoo browser percentage with JavaScript disabled, 2010][3]


This is about what I could find so far. But since this data is getting old, I wonder what the percentages are today. 

I also looked at [Statcounter][4], which seems to be the only company left to still openly publish browser statistics. But they do not publish data about JavaScript. I know that [W3schools also publish stats][5], but since the target is aimed at developers, this data is extremely biased and therefore not interesting for me. (it has to be representative for ordinary users).


I, therefore, ask you to provide:

 * links to any open, freely available statistics which touches this area
 * Your own stats, preferably from larger sites with do not target developers

So if I understand `z-index` correctly, it would be perfect in this situation: 

![enter image description here][1]


  [1]: http://i.stack.imgur.com/UFHRb.jpg

I want to place the bottom image (the tag/card) below the div above it. So you can&#39;t see the sharp edges. How do I do this?

    z-index:-1 // on the image tag/card
    
or

    z-index:100 // on the div above

doesn&#39;t work either. Neither does a combination of anything like this. How come?


Why does z-index not work?

I cannot get `z-index` working on a `iframe` that contains a pdf file with IE8. It works with Google Chrome.

Example ([JSFiddle](http://jsfiddle.net/5J6zL/9/)):

    &lt;div id=&quot;div-text&quot;&gt;
          &lt;div id=&quot;shouldBeOnTop&quot;&gt;my text that should be on top&lt;/div&gt;
    &lt;/div&gt;
    &lt;div id=&quot;div-frame&quot;&gt;
        &lt;iframe src=&quot;http://legallo1.free.fr/french/CV_JLG.pdf&quot; width=&quot;200&quot; height=&quot;200&quot;/&gt;
    &lt;/div&gt;

**CSS**

&lt;!-- language: lang-css --&gt;

    #div-text{
        position:relative;
        left:210px;
        top:20px
    }
    
    #shouldBeOnTop{
        position:relative;
        right:60px;
        background-color:red;
        width:100px;
        z-index:2;
    }
    
    #div-frame{
        position:relative;
         z-index:1;
    }

I&#39;m using twitter bootstrap dropdown menu in a fixed navbar at the top of my page.

It all works fine but am having issues with the drop down menu items showing behind other page elements rather than in front of them.

If I have anything on the page with `position: relative` (like jquery ui accordion, or a google chart) then the drop down menu shows behind it.  Tried changing the `z-index` of the dd menu and of the nav-bar, but doesn&#39;t make any difference.

The only way I can get the menu to sit above the other content is to change the content to `position: fixed;` OR `z-index: -1;`  -but both of these solutions cause other problems.

Appreciate any help you can give me.

I think this is probably some standard issue with CSS positioning that I&#39;ve misunderstood, so haven&#39;t posted any code, but can do if needed.

Thanks.

Bring element to front using CSS

Suppose I have this code:

    &lt;div class=&quot;parent&quot;&gt;
        &lt;div class=&quot;child&quot;&gt;
            Hello world
        &lt;/div&gt;
    &lt;/div&gt;
    
    &lt;div class=&quot;wholePage&quot;&gt;&lt;/div&gt;

This jsFiddle: http://jsfiddle.net/ZjXMR/

Now, I need to have`&lt;div class=&quot;child&quot;&gt;` in above of `&lt;div class=&quot;wholePage&quot;&gt;` but in the jsFiddle you can see that the child element rendered before `&lt;div class=&quot;wholePage&quot;&gt;`.

If you remove the `parent` class `position` or `z-index`, everything works fine. This is the correct behavior that I need: http://jsfiddle.net/ZjXMR/1/

How can I do that with `z-index` and without removing anything from page?
