You can not &quot;attach&quot; a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as [LESS CSS](http://lesscss.org), though I advise you compile to CSS for production use.

It&#39;s as simple as adding 2 lines of code to your HTML file.

    &lt;link rel=&quot;stylesheet/less&quot; type=&quot;text/css&quot; href=&quot;styles.less&quot; /&gt;
    &lt;script src=&quot;less.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;


I am trying to write an iOS app using TDD and the new XCTest framework. One of my methods retrieves a file from the internet (given a NSURL object) and stores it in the user&#39;s documents. The signature of the method is similar to:

    - (void) fetchAndStoreImage:(NSURL *)imageUrl

I&#39;m trying to write the test for this method in a way that it doesn&#39;t fail if there is no connection to the internet. My approach (taken from a previous [question][1]) is to call the method using a NSURL to an image in the local file system.

When a new project with unit tests enabled is created, the Tests directory has a subdirectory named &#39;Supporting Files&#39;. I suppose that is where my test images should go. My question is how can I get a NSURL object that points to an image in this directory, as I wouldn&#39;t want test images to be bundled with the application. Any help is appreciated.

In a certain (consistent) point when my app is running, I consistently get the xcode error message 

&gt; Terminated due to memory error.

I cannot find the code causing the error, but I can tell what code is near the error (using breakpoints).

The error is caused directly after returning a certain cell in my implemenation of the

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

`UITableViewDataSource` delegate method. I can confirm that it is returning a valid `UITableViewCell`, but I think that explaining and posting that entire method would be a waste of your time. However, I suspect it might be caused by a rapid, massive allocation of memory.

It definitely says `Terminated due to memory error`, not memory pressure.

I would like to know what is message really means. Also, is there any way to debug this message? No crash report is generated.

I am using **ARC** and iOS 7.

Is it possible to debug &quot;Terminated due to memory error&quot;?

Hello I am new to web design. I would like to learn how to attach an SCSS file to an HTML file in the head tag :


    
    &lt;link href=&quot;example&quot; rel=&quot;stylesheet/scss&quot; type=&quot;text/css&quot;&gt;

I tried this but did not see the result. I guess that it&#39;s like the LESS framework. And another question: If I want to use SCSS I should compile it to hosting or not?

Hello I am new to web design. I would like to learn how to attach an SCSS file to an HTML file in the head tag :
<pre><code class="hljs language-bash">&#x3C;link href="example" rel="stylesheet/scss" type="text/css">

I tried this but did not see the result. I guess that it's like the LESS framework. And another question: If I want to use SCSS I should compile it to hosting or not?

currently I have the following code

    &lt;input type=&quot;number&quot; /&gt;

it comes out to something like this

![enter image description here][1]

The little selector things on the right allow the number to go into negative. How do I prevent that?

I am having doubts about using `type=&quot;number&quot;`, it is causing more problems than it is solving, I am going to sanity check it anyways, so should I just go back to using `type=&quot;text&quot;`?

How to make type=&quot;number&quot; to positive numbers only

I was watching a youtube video and I decided to investigate some parts of its video player.  I noticed that unlike most HTML5 video I have seen, Youtube&#39;s video player does not do a normal video source and instead utilizes a blob url as the source.  

Previously I have tested HTML5 videos and I found that the server starts streaming the whole video from  the start and buffers in the background the complete rest of the video.  This means that if your video is 300 megs, all 300 megs will be downloaded.  If you seek to the middle, it will start downloading from the seek position all the way to the end.  

Youtube does not work this way (at least in chrome).  Instead it manages to control buffering so it only buffers a certain amount while paused. It also seems to only buffer the relevant pieces, so if you skip around it will make sure not to buffer pieces that are unlikely to be watched.

In my attempts to investigate how this worked, I noticed the video src tag has a value of `blob:http%3A//www.youtube.com/ee625eee-2802-49b2-a13f-eb374d551d54`, which pointed me to &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/API/Blob&quot;&gt;blobs&lt;/a&gt;, which then led me to &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Sending_and_Receiving_Binary_Data&quot;&gt;typed arrays&lt;/a&gt;.  Using those two resources I am able to load a mp4 video into a blob and display it in a HTML5 video tag.

However, what I am now stuck on is how Youtube deals with the pieces.  Looking at the network traffic it appears to sends requests to `http://r6---sn-p5q7ynee.c.youtube.com/videoplayback` which returns binary video data back in chunks of 1.1mb.  It also seems worth noting that most normal requests due to HTML5 video requests seem to receive a 206 response code back while it streams, yet youtube&#39;s playvideo calls get a 200 back.

I tried to attempt to only load a range of bytes (via setting the `Range` http header) which unfortunately failed (I&#39;m assuming because there was no meta-data for the video coming with the video).  

At this point I&#39;m stuck on figuring out how Youtube accomplishes this.  I came up with several ideas though none of which I am completely sold on:

1) Youtube is sending down self contained video and audio chunks with each `/videoplayback` call.  This seems like a pretty heavy burden on the upload side and it seems like it would be difficult to stitch these together to make it appear like it&#39;s one seemless video.  Also, the video tag seems to think it&#39;s one full video, judging from calling `$(&#39;video&#39;).duration` and `$(&#39;video&#39;).currentTime`, which leads me to believe that the video tag thinks it&#39;s a single video file.  Finally, the vidoe src tag never changes which makes me believe it is working with a singular blob and not switching out blobs.

2) Youtube constructs an empty blob pre-sized to the full video array and updates the blob with pieces as it downloads it.  It would then make sure the user has not gotten too close to the last downloaded piece (to prevent the user from entering an undownloaded section of the blob).  The problem that I see with this that I don&#39;t see any way to dynamically update a blob through javascript (although maybe I&#39;m just having trouble googling for it)

3) Youtube downloads the meta data and then starts constructing the blob in order by appending the video pieces as it downloads them.  The problem I see with this method is I don&#39;t understand how it would handle seeks in post-buffered territory.

Maybe I&quot;m just missing an obvious answer that&#39;s right in front of me.  Anyone have any ideas?


&lt;hr&gt;
&lt;b&gt;edit:&lt;b&gt; I just thought of a fourth option.  Another idea is they might use the file API to write the binary chunks to a file and use that file to stream off of.  The file API seems to have the ability to seek to specific positions, therefore allowing you to fill a video with empty bytes and fill them in as they are received.  This would definitely accommodate video seeking as well.

Is `id` an attribute or property of HTML?

should I do `$(&#39;#selector&#39;).attr(&#39;id&#39;);` or `$(&#39;#selector&#39;).prop(&#39;id&#39;);`

I&#39;ve read many articles and am still confused.

Could someone please explain to me what the differences between attributes &amp; properties in HTML/JS are in very simple language?

I&#39;m trying to resize some images with canvas but I&#39;m clueless on how to smoothen them.
On photoshop, browsers etc.. there are a few algorithms they use (e.g. bicubic, bilinear) but I don&#39;t know if these are built into canvas or not.

Here&#39;s my fiddle: http://jsfiddle.net/EWupT/

    var canvas = document.createElement(&#39;canvas&#39;);
    var ctx = canvas.getContext(&#39;2d&#39;);
    canvas.width=300
    canvas.height=234
    ctx.drawImage(img, 0, 0, 300, 234);
    document.body.appendChild(canvas);

The first one is a normal resized image tag, and the second one is canvas. Notice how the canvas one is not as smooth. How can I achieve &#39;smoothness&#39;?

I tried [this method][1] ([their fiddle][2]) to enable scrollable menu with Bootstrap, but with that approach, the scrollable menu expands its container -- [fiddle][3] -- the non-scrollable menu, correctly, does not do this.

How can I fix this? Suggestions on other approaches compatible with Bootstrap are appreciated too!

I would like to use `::before` to place SVG images before some selected elements:

```css
#mydiv::before {
  content: &#39;&lt;svg ... code here&lt;/svg&gt;&#39;;
  display: block;
  width: 22px;
  height: 10px;
  margin: 10px 5px 0 10px;
}
```
Above code just displays the plaintext.  
I checked the spec and there seem to be some restrictions on what `content` can be. CSS `content` property solution is preferable.

I am trying to insert a user icon inside username input field. 

I&#39;ve tried one of the solution from the [similar question](https://stackoverflow.com/questions/14736496/use-font-awesome-icons-in-css) 
knowing that `background-image` property won&#39;t work since [Font Awesome](http://fortawesome.github.io/Font-Awesome/) is a font.

The following is my approach and I can&#39;t get the icon display.

    .wrapper input[type=&quot;text&quot;] {
        position: relative;
    }
    
    .wrapper input[type=&quot;text&quot;]:before {

        position: absolute;
        top: 0px;
        left: -5px;
        content: &quot;\f007&quot;;
    }


I have font face declared in the default font awesome css so I wasn&#39;t sure if adding font-family above was the right approach.

   

     @font-face {
         font-family: &#39;FontAwesome&#39;;

I have to implement the following circle and line combination in CSS and I am looking for pointers on how to implement this effectively. The circles and lines should look like this:

I am able to implement the circles as such:

    span.step {

      border-radius: 0.8em;
      -moz-border-radius: 0.8em;
      -webkit-border-radius: 0.8em;

      margin-right: 5px;
      text-align: center;
      width: 1.6em; 
    }

but the lines are tricky for me to understand.

The size of the circle changes depending on whether it is the active step or not, and the color of the line connecting the circles changes as well depending on status. How would I accomplish this?

I am in the process of setting up a new Mac for work. I have installed Grunt &amp; Grunt CLI globally. Then I did a `npm install` inside a project folder to install all dependencies.  

No problems so far, but as soon as I try to run the `sass:dist` task, I get this warning:  

    Warning: You need to have Ruby and Sass installed and in your PATH for
    this task to work. More info:
    https://github.com/gruntjs/grunt-contrib-sass Use --force 
    to continue.

What I understand is that I need to have Ruby and Sass installed on a more global level for this task to run. As I am still pretty new to working with the terminal, I did a quick search to find out what `PATH` is - seems like its some system path (that can be changed) where important data is stored.  

Does this mean I can simply do a `sudo grunt install contrib-sass -g` to resolve the issue? And what about Ruby – I always thought its already installed on OS X?

Is there an option to include opacity on the colors you define to be your primary/secondary colors in the sass variables? In the fashion of the lighten($color, amount) function? 



Setting opacity on $primary-color in sass

I have a `:not` css selector in SASS mixin but it doesn&#39;t do anything:

**Code Snippet:**

    @mixin dropdown-pos($pos:right) {
      &amp;:not(.notip) {
        @if $comp-tip == true{
          @if $pos == right {
            top:$dropdown-width * -0.6;
            @include tip($pos:$pos);
          }
        }
      }
      &amp;.notip {
        @if $pos == right {
          top: 0;
          left:$dropdown-width * 0.8;
        }
      }
    }

The `.notip` class is being generated but no CSS is being generated for `:not(.notip)`.
