The values of `cursor` that represent what you&#39;re looking for are `not-allowed` and `no-drop`. These values are new to CSS3, so if you need browser compatibility you should specify an image instead.

The css  `cursor: not-allowed;` also works.

here is complete sample:

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-css --&gt;

    .not-allowed {
      cursor: not-allowed;
    }

&lt;!-- language: lang-html --&gt;

    &lt;input type=&quot;submit&quot; value=&quot;not-allowed&quot; class=&quot;not-allowed&quot; disabled /&gt;

&lt;!-- end snippet --&gt;



    #define SIZE 9
    int number=5;
    char letters[SIZE]; /* this wont be null-terminated */
    ... 

    char fmt_string[20];
    sprintf(fmt_string, &quot;%%d %%%ds&quot;, SIZE);
    /* fmt_string = &quot;%d %9d&quot;... or it should be */

    printf(fmt_string, number, letters);

Is there a better way to do this?

I have a javascript function:

    {
         //Do stuff and

    if(value2 &amp;&amp; value3)
    {

in this scenario how to pass value2 and value3 to the called method or how to return values in Java script.

**How do I resize an iframe from another domain**

-Edit


Scroll down for some solutions.. or read on how NOT to do this :D

After many hours of code hacking- the conclusion is that anything inside the iframe is not accessible, even the scrollbars that render on my domain. I have tried many techniques to no avail.

***To save you time don&#39;t even go down this route just use  sendMessages for cross domain communications.***
There are plug ins for HTML &lt; 5 that I use- Go to the bottom for a nice example :)


 ----


Past few days I have been trying to integrate an iframe into a site. This is a short term solution while the other side develops and API(could take months...) 
And because this is as short term solution we done want to use easyXDM- I have access to the other domain but its difficult enough asking them to add p3p header as it is.....

**3 iframes**

The closest solution I found was the 3 iframes- but it goes mental of chrome and safari so I cannot use that.

open in chrome

http://css-tricks.com/examples/iFrameResize/crossdomain.php#frameId=frame-one&amp;height=1179

**Measure the scrollbars**

I found a another post on how to use the scrollheight to try and resize the form.. in theory it works well but I could not apply it properly using the iframes scroll height.. 

    document.body.scrollHeight

That obvoisly uses the bodies height (cannot access these properties 100% is based on the clients display canvaz and not the x-domains document height)

I tried using jquery to get the iframes height

    $(&#39;#frameId&#39;).Height()

    $(&#39;#frameId&#39;).clientHeight

    $(&#39;#frameId&#39;).scrollHeight


return values different in chrome and ie - or just don&#39;t make sense at all.
The problem is that everything inside the frame is denied- even the scrollbar...

**Computed Styles**

But if I inspect and element in chrome of the iframe it bladdy shows me the documents dimensions inside the iframe (using jquery x-domain to get iframe.heigh - access denied)
There is nothing in the computed CSS ![enter image description here][1]


  [1]: https://i.stack.imgur.com/wox5C.jpg

Now how does chrome calculate that?  (edit- browser re-renders the page using its build in rendering engine to calcualte all these settings - but are not attached anywhere to prevent cross-domain fraud.. so..)

**HTML4**

I read specification of HTML4.x and it says there that there should be read-only values exposed via document.element but it&#39;s access denied via jquery

**Proxy Frame**

I went down the route of proxying the site back and calculating which is OK.. until a user logs in through the iframe and the proxy gets a login page instead of the actual content. Also to some calling the page twice is not acceptable 

http://www.codeproject.com/KB/aspnet/asproxy.aspx

http://www.johnchapman.name/aspnet-proxy-page-cross-domain-requests-from-ajax-and-javascript/

**Re-Render the page**

I did not go this far but there are jscript engines out there that will look at the source and re-render the page based on the source file . but it would require hacking those jscripts.. and thats not an ideal situation for commercial entities...
and some invole pure java applets or server side rendering

http://en.wikipedia.org/wiki/Server-side_JavaScript

http://htmlunit.sourceforge.net/ &lt;-java not jscript

http://maxq.tigris.org/

----

EDIT 09-2013
**UPDATE**

All this can do done with HTML5 sockets. But easyXDM is  great fallback for non HTML5 complaint pages.


**Solution 1** Very Great Solution! 

Using easyXDM

On your server you set up a page in the form of

    &lt;html&gt;
    &lt;head&gt;
    &lt;script src=&quot;scripts/easyXDM.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;
    &lt;script type=&quot;text/javascript&quot; language=&quot;javascript&quot;&gt;

        var transport = new easyXDM.Socket(/** The configuration */{
        remote: &quot;http://www.OTHERDOMAIN.com/resize_intermediate.html?url=testpages/resized_iframe_1.html&quot;,

        //ID of the element to attach the inline frame to
        container: &quot;embedded&quot;,
        onMessage: function (message, origin) {
            var settings = message.split(&quot;,&quot;);
            //Use jquery on a masterpage.
            //$(&#39;iframe&#39;).height(settings[0]);
            //$(&#39;iframe&#39;).width(settings[1]);

            //The normal solution without jquery if not using any complex pages (default)
            this.container.getElementsByTagName(&quot;iframe&quot;)[0].style.height = settings[0];
            this.container.getElementsByTagName(&quot;iframe&quot;)[0].style.width = settings[1];
        }
    });

    &lt;/script&gt;
   
    &lt;/head&gt;

    &lt;body&gt;
        &lt;div id=&quot;embedded&quot;&gt;&lt;/div&gt;
    &lt;/body&gt;


and on the callers domain they just need to add the intermiedate_frame html and easyXDM.js  in the same place. Like a parent folder - then you can access relative directories or a contained folder just for you.

OPTION 1
-
**If you don&#39;t want to add scripts to all pages look at option 2!**

Then they can just add a simple jscript to the end of each the pages you need the resize to occur. No need to include the easyxdm in each of these pages.

     &lt;script type=&quot;text/javascript&quot;&gt;
    			window.onload = function(){ parent.socket.postMessage( (parseInt(document.body.clientHeight)) + &quot;,&quot; + ( document.body.clientWidth ) );  };
            &lt;/script&gt;

I have modified the parameters it sends. If you want the width to work properly then the pages on the otherdomain need to include the width of the page in a style somwhere that look something similar to:

    &lt;style type=&quot;text/css&quot;&gt;
                html, body {
                    overflow: hidden;
                    margin: 0px;
                    padding: 0px;
                    background-color: rgb(75,0,85);
    				color:white;
    				width:660px
                }
    			a {
    			color:white;
    			visited:white;
    			}
            &lt;/style&gt;

This works great for me. If the width is not included then the frame behaves a bit strange and kind&#39;of tries to guess what it should be .. and will not shrink down if you need it to.


OPTION 2
-
**Modify the intermediate frame to poll for changes**

Your intermediate frame should look something like this..

 

        &lt;!doctype html&gt;
    &lt;html&gt;
        &lt;head&gt;
    	
            &lt;title&gt;Frame&lt;/title&gt;
            &lt;script type=&quot;text/javascript&quot; src=&quot;easyXDM.js&quot;&gt;
            &lt;/script&gt;
            &lt;script type=&quot;text/javascript&quot;&gt;
                var iframe;
                var socket = new easyXDM.Socket({
                    //This is a fallback- not needed in many cases
    				swf: &quot;easyxdm.swf&quot;,
                    onReady: function(){
                        iframe = document.createElement(&quot;iframe&quot;);
                        iframe.frameBorder = 0;
    					document.body.appendChild(iframe);
                        iframe.src = &quot;THE HOST FRAME&quot;;
    			iframe.onchange = messageBack();
    					
                    },
                    onMessage: function(url, origin){
                        iframe.src = url;
                    }
                });
    			
    			//Probe child.frame for dimensions.
    			function messageBack(){
    				socket.postMessage ( iframe.contentDocument.body.clientHeight + &quot;,&quot; + iframe.contentDocument.body.clientWidth); 
    			};
    			
    			//Poll for changes on children every 500ms.
    			setInterval(&quot;messageBack()&quot;,500); 
    				
            &lt;/script&gt;
            &lt;style type=&quot;text/css&quot;&gt;
                html, body {
                    overflow: hidden;
                    margin: 0px;
                    padding: 0px;
                    width: 100%;
                    height: 100%;
                }
                
                iframe {
                    width: 100%;
                    height: 100%;
                    border: 0px;
                }
            &lt;/style&gt;
        &lt;/head&gt;
        &lt;body&gt;
    	 
        &lt;/body&gt;
    &lt;/html&gt;


The interval could be made more efficient to chaeck if size has change and only send if the dimensions changes isntead of posting messaging every 500ms. If you implement this check then you can change the polling as low as 50ms! have fun

----

Work across browsers and is fast. Great debugging features !!

    Excellent Work to  Sean Kinsey  who made the script!!!


----


**Solution 2** (Works but not great)

So basically if you have a mutual agreement with the other domain then you can add a library to handle sendmessage.  If you do not have any access the the other domain.. Keep on looking for more hacks- because I could not find or fully justify these I found.

So the other domain will include these in there Head tag

    &lt;script src=&quot;scripts/jquery-1.5.2.min.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;
    &lt;script src=&quot;scripts/jquery.postmessage.min.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;
    &lt;script src=&quot;scripts/club.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;

In the club.js is just some custom calls i made for resize calls and contains..

     $(document).ready(function () {   
        var parent_url = decodeURIComponent( document.location.hash.replace( /^#/, &#39;&#39; ) ),link;
	//Add source url hash to each url to authorise callback when navigating inside the frame.Without this clicking any links will break the communication and no messages will be received
	$(&#39;a[href]&#39;).each(function(){ 
         this.href = this.href + document.location.hash ;
	});
	//Get the dimensions and send back to calling page.
	var h1 = document.body.scrollHeight;
	var w1 = document.body.scrollWidth;
	$.postMessage({ if_height: h1, if_width: w1 }, parent_url, parent );
      });

And your page will do all the hard work and has a nice script...

      //This is almost like request.querystring used to get the iframe data
      function querySt(param, e) {
             gy = e.split(&quot;&amp;&quot;);
             for (i = 0; i &lt; gy.length; i++) {
                 ft = gy[i].split(&quot;=&quot;);
                 if (ft[0] == param) {
                     return ft[1];
                 }
             }
         }


         $(function () {
             // Keep track of the iframe dimensions.
             var if_height;
             var if_width;
             // Pass the parent page URL into the Iframe in a meaningful way (this URL could be
             // passed via query string or hard coded into the child page, it depends on your needs).
             src = &#39;http://www.OTHERDOAMIN.co.uk/OTHERSTARTPAGE.htm&#39; + &#39;#&#39; + encodeURIComponent(document.location.href),
             // Append the Iframe into the DOM.
             iframe = $(&#39;&lt;iframe &quot; src=&quot;&#39; + src + &#39;&quot; width=&quot;100%&quot; height=&quot;100%&quot; scrolling=&quot;no&quot; frameborder=&quot;0&quot;&gt;&lt;\/iframe&gt;&#39;).appendTo(&#39;#iframe&#39;);

             // Setup a callback to handle the dispatched MessageEvent event. In cases where
             // window.postMessage is supported, the passed event will have .data, .origin and
             // .source properties. Otherwise, this will only have the .data property.
             $.receiveMessage(function (e) {
                 // Get the height from the passsed data.
                 //var h = Number(e.data.replace(/.*if_height=(\d+)(?:&amp;|$)/, &#39;$1&#39;));
                 var h = querySt(&quot;if_height&quot;, e.data);
                 var w = querySt(&quot;if_width&quot;, e.data);


                 if (!isNaN(h) &amp;&amp; h &gt; 0 &amp;&amp; h !== if_height) {
                     // Height has changed, update the iframe.
                     iframe.height(if_height = h);
                 }
                 if (!isNaN(w) &amp;&amp; w &gt; 0 &amp;&amp; w !== if_width) {
                     // Height has changed, update the iframe.
                     iframe.width(if_width = w);
                 }
                 //For debugging only really- can remove the next line if you want
                 $(&#39;body&#39;).prepend(&quot;Recieved&quot; + h + &quot;hX&quot; + w + &quot;w .. &quot;);
                 // An optional origin URL (Ignored where window.postMessage is unsupported).
               //Here you must put the other domain.com name only! This is like an authentication to prevent spoofing and xss attacks! 
             }, &#39;http://www.OTHERDOMAIN.co.uk&#39;);
         });

OPTION 3

Their is now a small JS library for managing resizing cross-domain iFrames, it still requires the iFrame to have a bit of JavaScript in it, however, this is just 2.8k (765 bytes Gzipped) of native JS that does not have any dependancies and it doesn&#39;t do anything until called by the parent page. This means it&#39;s a nice guest on other people systems. 

This code uses mutationObserver to detect DOM changes and also looks out for resize events, so that the iFrame remains sized to the content. Works in IE8+.

&lt;!-- language-all: lang-css --&gt;
I&#39;m trying to style a `select` element using CSS3. I&#39;m getting the results I desire in WebKit (Chrome / Safari), but Firefox isn&#39;t playing nicely (I&#39;m not even bothering with IE). I&#39;m using the CSS3 `appearance` property, but for some reason I can&#39;t shake the drop-down icon out of Firefox. 

Here&#39;s an example of what I&#39;m doing: http://jsbin.com/aniyu4/2/edit

    #dropdown {
     -moz-appearance: none;
     -webkit-appearance: none;
     appearance: none;
     background: transparent url(&#39;example.png&#39;) no-repeat right center;
     padding: 2px 30px 2px 2px;
     border: none;
    }

As you can see, I&#39;m not trying for anything fancy. I just want to remove the default styles and add in my own drop-down arrow. Like I said, great in WebKit, not great in Firefox. Apparently, the `-moz-appearance: none` doesn&#39;t get rid of the drop-down item.

Any ideas? No, JavaScript is not an option

 1. Both indexedDB and local storage are key value stores. What is the
    advantage of having two key/value stores?
 2. indexedDB is asynchronous, but joins (the most time-consuming thing)
        are manual. They appear to run in the same thread as the async calls
        were made. How will this not block the UI?
 3. indexedDB allows a larger store. Why not increase the size of the
            HTML5 store?      
 4. I&#39;m scratching my head. What is the point of indexedDB?

How is indexedDB conceptually different from HTML5 local storage?

When I try this

    &lt;option disabled = &quot;disabled&quot; &lt;!-- Used to disable any particular option --&gt;
            selected = &quot;selected&quot; &lt;!-- Used to pre-select any particular option --&gt;
            label = &quot;string&quot;      &lt;!-- Used to provide a short version of the content in the option --&gt; 
            value = &quot;value&quot;&gt;      &lt;!-- The actual value that will be send to the server. If omitted the content between the option opening and closing tags will be send. --&gt;

    Option 1
    &lt;/option&gt;

I am trying to comment the attributes and values inside the openning tag of the element. However this does not work as browsers (tested on IE9, FF4.01, GG11, AF5 and Opera11) treat everything followed after the disabled=&quot;disabled&quot; as either comment or content.

Are HTMl Comments not allowed inside the opening tag of elements?

I have 3 `div` elements.

1st `div` is bigger (wrap) and has `position:relative;`

2nd `div` is positioned absolute to the 1st `div` relative positioning (and is included in the 1st `div`)

3rd `div` is contained in the 2nd `div` and also has absolute positioning.

    &lt;div id=&quot;1st&quot;&gt;
       &lt;div id=&quot;2nd&quot;&gt;
         &lt;div id=&quot;3rd&quot;&gt;&lt;/div&gt;
       &lt;/div&gt;
    &lt;/div&gt;

Why is the 3rd `div` position absolute to the 2nd `div` (which is also absolute position to the 1st `div`) and not to 1st `div` that has relative position ?

Because the 3rd `div` is absolute positioning to the absolute positioned 2nd `div`.

Absolute positioning inside absolute position

I&#39;m wondering about the support for side specific inner shadows in css3.

I know this works great on supported browsers.

    div { box-shadow:inset 0px 1px 5px black; }

I&#39;m just curious as to whether there is a way to achieve something like: 

    div { box-shadow-top:inset 0px 1px 5px black; }





Can CSS3 box-shadow:inset do only one or two sides? like border-top?

Is it possible to use CSS3 transitions with a different delay switching between &quot;states&quot;? For example, I&#39;m trying to make an element immediately higher upon hover then on &#39;mouseout&#39; to wait a second before sliding back to the element&#39;s initial height.

**Demo page:** [jsfiddle.net/RTj9K][1] (hover black box in top-right corner)

**CSS:** `#bar { transition:.4s ease-out 0, 1s; }`

I thought the timings on the end related to delay but it doesn&#39;t seem to be working the way I&#39;d imagined.
