There are two different types of comments to consider in SASS.  

 1. Single line comments `//` will be removed by the .scss pre-procesor, and won&#39;t appear in your .css file.  
 2. Multiline comments `*/` are valid CSS, and will be preserved* between the translation from .scss to your .css file.  

* Except for some compressed modes, unless you start the comment with a `!`.  See http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#comments.  

It sounds like inline comments `//` are what you&#39;re looking for.

**Yes**, you can do it in **SCSS**.

Use inline comment: `//`.

These single-line comments are removed in the CSS output.

I&#39;ve got a web application where I have the typical problem that it requires different configuration files for different environments. Some configuration is placed in the application server as JNDI datasources, however some configuration stays in property files.

Therefore I want to use the Spring profiles feature.

My problem is that I don&#39;t get the test case running.

context.xml:

    &lt;context:property-placeholder 
      location=&quot;classpath:META-INF/spring/config_${spring.profiles.active}.properties&quot;/&gt;

Test:
   
    @RunWith(SpringJUnit4ClassRunner.class)
    @TestExecutionListeners({
		TestPreperationExecutionListener.class
		})
    @Transactional
    @ActiveProfiles(profiles = &quot;localtest&quot;)
    @ContextConfiguration(locations = {
		&quot;classpath:context.xml&quot; })
    public class TestContext {

	  @Test
	  public void testContext(){

	  }
    }

The problem seems to be that the variable for loading the profile isn&#39;t resolved:

    Caused by: java.io.FileNotFoundException: class path resource [META-INF/spring/config_${spring.profiles.active}.properties] cannot be opened because it does not exist
	at org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:157)
	at org.springframework.core.io.support.PropertiesLoaderSupport.loadProperties(PropertiesLoaderSupport.java:181)
	at org.springframework.core.io.support.PropertiesLoaderSupport.mergeProperties(PropertiesLoaderSupport.java:161)
	at org.springframework.context.support.PropertySourcesPlaceholderConfigurer.postProcessBeanFactory(PropertySourcesPlaceholderConfigurer.java:138)
	... 31 more

The current profile should be set with the `@ActiveProfile` annotation. As it&#39;s a test case I won&#39;t be able to use the `web.xml`. If possible I&#39;d like to avoid runtime options as well. The test should run as is (if possible).

How can I properly activate the profile? Is it possible to set the profile with a context.xml? Could I declare the variable in a test-context.xml that is actually calling the normal context?

Spring profiles and testing

I have a table with `id`, `year` and `count`. 

I want to get the `MAX(count)` for each `id` and keep the `year` when it happens, so I make this query:

    SELECT id, year, MAX(count)
    FROM table
    GROUP BY id;

Unfortunately, it gives me an error: 

&gt; ERROR:  column &quot;table.year&quot; must appear in the GROUP BY clause or be
&gt; used in an aggregate function

So I try:

    SELECT id, year, MAX(count)
    FROM table
    GROUP BY id, year;

But then, it doesn&#39;t do `MAX(count)`, it just shows the table as it is. I suppose because when grouping by `year` and `id`, it gets the max for the `id` of that specific year.

So, how can I write that query? I want to get the `id`&#180;s `MAX(count)` and the year when that happens.

Can I keep an inline comment like this in my `.scss` file

    thead {
        display: table-header-group; // h5bp.com/t
    }

I don&#39;t want this comment in my CSS output.

Does SCSS support inline comments?

Can I keep an inline comment like this in my <code>.scss</code> file

I want to set a width in percentage in scss via calculation, but it gives me errors..

&gt; Invalid CSS after &quot;...-width: (4/12)%&quot;: expected expression (e.g. 1px,
&gt; bold), was &quot;;&quot;

I want to do something like


    $my_width: (4/12)%;
    
    div{
    width: $my_width;
    }

how do I add the % sign in there?

Placing the SVG output directly inline with the page code I am able to simply modify fill colors with CSS like so:

&lt;!-- language: lang-css --&gt;

    polygon.mystar {
        fill: blue;
    }​
    
    circle.mycircle {
        fill: green;
    }


This works great, however I&#39;m looking for a way to modify the &quot;fill&quot; attribute of an SVG when it&#39;s being served as a BACKGROUND-IMAGE.  

&lt;!-- language: lang-css --&gt;

    html {      
        background-image: url(../img/bg.svg);
    }


How can I change the colors now?  Is it even possible?

For reference, here are the contents of my external SVG file:

&lt;!-- language: lang-svg --&gt;

    &lt;svg version=&quot;1.1&quot; id=&quot;Layer_1&quot; xmlns=&quot;http://www.w3.org/2000/svg&quot; xmlns:xlink=&quot;http://www.w3.org/1999/xlink&quot; x=&quot;0px&quot; y=&quot;0px&quot;
    	 width=&quot;320px&quot; height=&quot;100px&quot; viewBox=&quot;0 0 320 100&quot; enable-background=&quot;new 0 0 320 100&quot; xml:space=&quot;preserve&quot;&gt;
    &lt;polygon class=&quot;mystar&quot; fill=&quot;#3CB54A&quot; points=&quot;134.973,14.204 143.295,31.066 161.903,33.77 148.438,46.896 151.617,65.43 134.973,56.679 
    	118.329,65.43 121.507,46.896 108.042,33.77 126.65,31.066 &quot;/&gt;

As you can see on the picture the text alignment for each colum is set to left alignment. Is there any way to change this? So far I&#39;ve tried within my CSS file:

&lt;!-- language: css --&gt;

    #Cols{
    	text-align: right;
    }

I have also tried:

    }

Does anyone know how I can change the alignment to right?

Currently the modal slide down effect is done by adding the `fade` class to the modal div. Is it possible to change the effect to sliding from the side (or from the bottom) by changing the css?  I couldn&#39;t find any information online on how to do this and don&#39;t know enough css to do this myself.

html:

    &lt;div id=&#39;test-modal&#39; class=&#39;modal fade hide&#39;&gt;
      &lt;div&gt;Stuff&lt;/div&gt;

Converts scss to css

I would like to start using Compass and Sass to speed up development. At the moment, I have installed Sass on a mac and instructed it to watch a Scss file for input, and a CSS file for generated output.

From many articles, Sass is used with Compass, I&#39;m wondering why that is the case and just what does Compass add that Sass comes without? If you can give an example, the better.

What are Compass and Sass and how do they differ?

I&#39;ve been refactoring my CSS to a SASS style sheet recently. I&#39;m using the [Mindscape Web Workbench extension][1] for VS2012, which re-generates the CSS each time you save your SCSS. I started with code similar to this:

&lt;!-- language-all: css --&gt;

    /* Starting point: */
    h1 { font-size: 1.5em; /* 24px &#247; 16px */ }

Then I tried to refactor it first to this:

    /* Recfator: */
    h1 { font-size: (24px / 16px)em; }

But this unfortunately produces:

    /* Result: */
    h1 { font-size: 1.5 em; }              /* doesn&#39;t work, gives &quot;1.5 em&quot; */

Notice the **extra space**, which I don&#39;t want there. I&#39;ve tried several alternatives, here are a few:

    h1 { font-size: (24/16)em; }           /* doesn&#39;t work, gives &quot;1.5 em&quot; */
    h2 { font-size: 24 / 16em; }           /* doesn&#39;t work, gives &quot;24/16em&quot; */
    h3 { font-size: (24px / 16px) * 1em; } /* works but &quot;* 1 em&quot; feels unnecessary */
    h4 { font-size: (24em) / 16; }         /* works, but without &quot;px&quot; it&#39;s not 
                                              really conveying what I mean to say */

I&#39;ve also tried these variants with variables (because I want those anyways), but that didn&#39;t change the situation much. To keep the examples in this question sleek I&#39;ve left out variables. However, I&#39;d happily accept a solution that relies on using variables (in a clean way).

I&#39;ve gone through the [relevant SASS documenation on &#39;/&#39;][2], and appreciate that this is a tough one for SASS because the &#39;/&#39; character already has a meaning in basic CSS. Either way, I was hoping for a clean solution. Am I missing something here?

PS. [This blogpost][3] does offer one solution, using a user defined function. That seems a bit heavy-weight though, so I&#39;m interested if there&#39;s &quot;cleaner&quot; solutions in line with my attempts above. If someone can explain the &quot;function approach&quot; is the better (or even only) solution then I&#39;ll accept that as an answer too.

PS. [This related question][4] seems to be about the same thing, though that one specically wants to do further calculations. [The accepted answer there][5] is my third workaround (multiplying by `1em`), but I&#39;d love to know if there&#39;s a different (cleaner) way if I&#39;m willing to forego the ability to do further calculations. Perhaps the method mentioned in said question (&quot;interpolation&quot;) is useful for me?

----------
***Bottom line:** how can you cleanly append the unit type (e.g. `em`) to the result of a calculation in SASS?*
