Yes, it&#39;s possible, and you basically just described how. Disable it for the parent and enable it for the child.

[**`pointer-events`**][1] is supported in almost every browser, including **IE11** 

Please note that `pointer-events: all` is for **SVG only**. 

For HTML, only `auto` and `none` are supported values.

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-css --&gt;

    .parent {
      pointer-events: none;
    }

    .child {
      pointer-events: auto;
    }

&lt;!-- language: lang-html --&gt;

    &lt;div class=&quot;parent&quot;&gt;
      &lt;a href=&quot;#&quot;&gt;Parent&lt;/a&gt;
      &lt;div class=&quot;child&quot;&gt;
        &lt;a href=&quot;#&quot;&gt;Child&lt;/a&gt;
      &lt;/div&gt;
    &lt;/div&gt;

&lt;!-- end snippet --&gt;

On the child element&#39;s style, add

    pointer-events: auto;

`pointer-events: all` didn&#39;t work for me, and apparently applies to SVG elements only.

As a possible solution in some cases you can set

```css
height: 0;
```

to parent element and let child element to overflow

I&#39;m trying to create an asynchronous channel and I&#39;ve been looking at http://golang.org/ref/spec#Making_slices_maps_and_channels. 

    c := make(chan int, 10)         // channel with a buffer size of 10

What does it mean that the buffer size is 10? What specifically does the buffer size represent/limit?

What is channel buffer size?

I have a jinja2 template (.html file) that I want to render (replace the tokens with values from my py file).  Instead of sending the rendered result to a browser, however, I want to write it to a new .html file.  I would imagine the solution would also be similar for a django template.

How can I do this?

Is it possible for the child of a div set to `pointer-events: none` to have pointer events?


I need the div that holds another div to allow pointer events to pass through, but for the div itself to still have events. 

Is this possible?

I have a nested data structure containing objects and arrays. How can I extract the information, i.e. access a specific or multiple values (or keys)?

For example:

    var data = {
        code: 42,
        items: [{
            id: 1,
            name: &#39;foo&#39;
        }, {
            id: 2,
            name: &#39;bar&#39;
        }]
    };

How could I access the `name` of the second item in `items`?

Consider this [JSFiddle][1]. It works fine in Firefox (14.0.1), but fails in Chrome (21.0.1180.75), Safari (?) and Opera(12.01?) on both Windows (7) and OS X (10.8). As far as I can tell the issue is with either the `setData()` or `getData()` methods on the `dataTransfer` object. Here&#39;s the relevant code from the JSFiddle.

    var dragStartHandler = function (e) {
        e.originalEvent.dataTransfer.effectAllowed = &quot;move&quot;;
        e.originalEvent.dataTransfer.setData(&quot;text/plain&quot;, this.id);
    };
    
    var dragEnterHandler = function (e) {
        //  dataTransferValue is a global variable declared higher up.
        //  No, I don&#39;t want to hear about why global variables are evil,
        //  that&#39;s not my issue.
        dataTransferValue = e.originalEvent.dataTransfer.getData(&quot;text/plain&quot;);
        
        console.log(dataTransferValue);
    };

As far as I can tell this should work perfectly fine and if you look at the console while dragging an item you will see the id written out, which means that it&#39;s finding the element just fine and grabbing it&#39;s id attribute. The question is, is it just not setting the data or not getting the data?

I&#39;d appreciate suggestions because after a week of working on this with three attempts and some 200+ versions, I&#39;m starting to loose my mind. All I know is it used to work back in version 60 or so and that specific code hasn&#39;t changed at all...

&lt;s&gt;Actually, one of the major differences between 6X and 124 is that I changed the event binding from `live()` to `on()`. I don&#39;t think that&#39;s the issue, but I&#39;ve come to see a couple failures from Chrome when it comes to DnD while working on this.&lt;/s&gt; This has been debunked. The event binding method has no effect on the issue.

**UPDATE**

I&#39;ve created a new [JSFiddle][2] that strips out absolutely everything and just leaves the event binding and handlers. I tested it with jQuery 1.7.2 and 1.8 with both `on()` and `live()`. The issue persisted so I dropped down a level and removed all frameworks and used pure JavaScript. The issue *still* persisted, so based on my testing it&#39;s not my code that&#39;s failing. Instead it appears that Chrome, Safari and Opera are all implementing either `setData()` or `getData()` off spec or just failing for some reason or another. Please correct me if I&#39;m wrong.

Anyway, if you take a look at the new JSFiddle you should be able to replicate the issue, just look at the console when you&#39;re dragging over an element designated to accept a drop. I&#39;ve gone ahead and opened a ticket with [Chromium][3]. In the end I may still be doing something wrong, but I simply don&#39;t know how else to do DnD at this point. The new JSFiddle is as stripped down as it can get...

I have this element:

    &lt;div style=&quot;width: 100%; height: 10px;&quot;&gt;&lt;/div&gt;

I want to get it&#39;s width in pixels. I just tried this:

    document.getElementById(&#39;banner-contenedor&#39;).style.width

Which returns `100%`. Is it possible to actually get the element&#39;s width in pixels with JavaScript?

I am using following code to execute some statements after page load.

But this code does not work properly. The function is called even if some images or elements  are loading. What I want is to call the function the the page is loaded completely.

I am creating a sample website which has three divisions horizontally.
I want the left most div to be 25% width, the middle one to be 50% width, and right to be 25% width so that the divisions fill all the 100% space horizontally.

        &lt;/title&gt;

How to position three divs in html horizontally?

I am trying to hide the first 3 elements having the class `.row` inside the block `.container`.

What I&#39;m doing is hiding all the `.row` first, and then I am trying to display the first 3 `.row` by using `.row:nth-child(-n+3)`

jsfiddle here:  http://jsfiddle.net/z8fMr/1/

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-css --&gt;

    .row {
      display: none;
    }

    .row:nth-child(-n+3) {
      display: block;
    }

&lt;!-- language: lang-html --&gt;

    &lt;div class=&quot;content&quot;&gt;

      &lt;div class=&quot;notarow&quot;&gt;I&#39;m not a row and I must remain visible&lt;/div&gt;
      &lt;div class=&quot;row&quot;&gt;Row 1&lt;/div&gt;
      &lt;div class=&quot;row&quot;&gt;Row 2&lt;/div&gt;
      &lt;div class=&quot;row&quot;&gt;Row 3&lt;/div&gt;
      &lt;div class=&quot;row&quot;&gt;Row 4&lt;/div&gt;
      &lt;div class=&quot;row&quot;&gt;Row 5&lt;/div&gt;
      &lt;div class=&quot;row&quot;&gt;Row 6&lt;/div&gt;

    &lt;/div&gt;

&lt;!-- end snippet --&gt;

I have two problems here:

1. Row 3 is not displayed, am I using nth-child in the wrong way?
2. Is there a better practice than hiding everything and then creating a specific rule to display the n first elements that I want? Is there a way in css to just display the first 3 `.row` and then hide all the other `.row` ?

Thanks.

How to show the first N elements of a block and hide the others in css?

A couple of questions concerning this:

 - Is it good practice?
 - Will it, on a large scale, result in better load times?
 - Can it result in browsers &#39;breaking&#39;?
 - Is the same true for the last function in JavaScript  (/jQuery)?

What I mean is stuff like this:

&lt;!-- language: lang-css --&gt;

    #myElement {
      position: absolute;
      top: 0;
      left: 0
    }

For instance, if I want to get rid of the border that is labeled important:
    
    $(&quot;.someclass&quot;).css(&#39;border&#39;,&#39;none&#39;); //does not work
