You can use `rgba`, i.e. 
 
    $primary: rgba(20,20,20, .5);

It works for hex values as well

    $primary: rgba(#4B00B5, .3);

You can also set the opacity of colors based on a variable value. For example:

    $primary-color: #a61723;
    ....
    color: rgba($primary-color, .5);

I want to label my x axis at follows :

    pylab.xlabel(&#39;metres 10^1&#39;)

But I don&#39;t want to have the ^ symbol included .

    pylab.xlabel(&#39;metres 10$^{one}$&#39;)

This method works and will superscript letters but doesn&#39;t seem to work for numbers .
If I try :

    pylab.xlabel(&#39;metres 10$^1$&#39;)

It superscripts a letter N for some reason .

Anyone know how to superscript numbers in python plots ?
thanks .

I downloaded and installed Visual Studio 2013 Profession Trial on my Windows 7 64-bit computer ( RAM is 6 GB). But, when I start it for the first time, it says &#39;We&#39;re getting things ready. Thanks for your patience&#39; and its been on for about an hour.

Is this normal with VS 2013?

**EDIT 1:**
I left my computer running the whole night, and by morning it had re-booted. After the re-boot, VS 2013 seems to be starting quickly. So, its hard to say why Visual Studio 2013 was taking hours to start up the first time.

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?

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)`.

I have a gulp task that is attempting to convert .scss files into .css files (using gulp-ruby-sass) and then place the resulting .css file into the same place it found the original file. The problem is, since I&#39;m using a globbing pattern, I don&#39;t necessarily know where the original file is stored. 

In the code below I&#39;m trying to use gulp-tap to tap into the stream and figure out the file path of the current file the stream was read from:

    gulp.task(&#39;convertSass&#39;, function() {
        var fileLocation = &quot;&quot;;
        gulp.src(&quot;sass/**/*.scss&quot;)
            .pipe(sass())
            .pipe(tap(function(file,t){
                fileLocation = path.dirname(file.path);
                console.log(fileLocation);
            }))
            .pipe(gulp.dest(fileLocation));
    });

Based on the output of the `console.log(fileLocation)`, this code seems like it should work fine. However, the resulting CSS files seem to be placed one directory higher than I&#39;m expecting. Where it should be `project/sass/partials`, the resulting file path is just `project/partials`. 

If there&#39;s a much simplier way of doing this, I would definitely appreciate that solution even more. Thanks!

Error: SASS installation for windows

I would like to use google web starter kit. I installed node.js v0.12.0, `node-sass` &amp; `gulp`.

And then ran:

    $ sudo npm install

When I typed `gulp serve` then got this error:

    Using gulpfile ~/web-starter-kit/gulpfile.js Starting &#39;styles&#39;... &#39;styles&#39; errored after 93 ms 
    Error: `libsass` bindings not found. Try reinstalling `node-sass`? at getBinding

I reinstalled node and gulp but this doesn&#39;t help.

What should I do next?

Try reinstalling `node-sass` on node 0.12?

I am using web pack with sass loader like this:

    module.exports = {
      module: {
        loaders: [
          {
            test: /\.scss$/,
            loader: &quot;style!css!sass&quot;
          }
        ]
      }
    };

But i see the styles apply to the style tag, where is the generate css file?

I have an element with text in it. Whenever I decrease the opacity, then I decrease the opacity of the WHOLE body. Is there any way I can just make the `background-image` darker, and not everything else?
