Just remove the comma like this:

    &lt;article class=&quot;column wrapper&quot;&gt; 

From the standard 

&gt; 7.5.2 Element identifiers: the id and class attributes
&gt; 
&gt; Attribute definitions
&gt; 
&gt; id = name [CS]  
&gt; This attribute assigns a name to an element. This name
&gt; must be unique in a document.
&gt; 
&gt; class = cdata-list [CS]  
&gt; This attribute
&gt; assigns a class name or set of class names to an element. Any number
&gt; of elements may be assigned the same class name or names. Multiple
&gt; class names must be separated by white space characters.

Yes, just put a space between them. 

    &lt;article class=&quot;column wrapper&quot;&gt;

Of course, there are many things you can do with CSS inheritance. Here is an [article for further reading][1].


  [1]: https://developer.mozilla.org/en-US/docs/Learn/CSS/Introduction_to_CSS/Cascade_and_inheritance

To assign **multiple classes** to an **html element**, include both class names within the quotations of the class attribute and have them separated by a space:

    &lt;article class=&quot;column wrapper&quot;&gt; 

In the above example, `column` and `wrapper` are two separate css classes, and both of their properties will be applied to the `article` element.

you need to put a dot between the class like

class=&quot;column.wrapper&quot;&gt;

I am running Visual Studio 2010 (as Admin), IIS 7 on Windows 7 x64.
I am able to run the ASP.NET web site in IIS 7 without debugging just fine, but when I press F5 to debug it, I get:

&gt; Unable to start debugging on the web server. Could not start ASP.NET debugging. More information may be available by starting the project without debugging.

Unfortunately the help link is not helping me much and leads down a heck of a large tree of things.

I checked the following:

* Security requirements — I don&#39;t recall having to do anything special before. The worker process in IIS7 is w3wp.exe. It says that if it&#39;s running as ASPNET or NETWORK SERVICE I must have Administrator privileges to debug it. How do I find out if I need to change something here?

* Web site Property Pages &gt; Start Options &gt; Debuggers &gt; ASP.NET is checked.
  Use custom server is set to the URL of the site (which works fine without debugging).

* Debugging is enabled in `web.config`.

* Application is using ASP.NET 3.5 (I want to move to 4.0 eventually but I have some migration to deal with).

* Application pool: Classing .NET AppPool (also tried DefaultAppPool).

Any ideas where I can check next?

Surely it shouldn&#39;t be that hard to install IIS, VS, create a web site, and start testing it?

Thanks in advance.

I am currently validating my JavaScript against JSLint and making progress on, it&#39;s assisting me to write better JavaScript - in particular in working with the Jquery library.

I have now come across **JSHint**, a fork of **JSLint**.  
So I am wondering for web applications, which are very much JavaScript was driven, which is the better or most applicable validation tool to work against:  

- JSLint or JSHint?  

I want to decide now on a validation mechanism and moving forward, use this for client side validation.

And Difference between jshint and jslint? Please explain in single javascript example.

I want to show my web-site in landscape mode only, is it possibile? It does not matter what the orientation is of device in user&#39;s hand but the web site will always be in landscape mode. I have seen iPhone application working like that but can this be done for a web-site?



forcing web-site to show in landscape mode only

I have this line of code:

	$(&#39;#sitesAccordion .groupOfSites&#39;).click(function() {
        var lastOpenSite = $(this).siblings().hasClass(&#39;:not(.closedTab)&#39;);
        console.log(lastOpenSite);
	});

I get &quot;false&quot; instead of getting one of the other elements (assuming that there is one - and there must be). I guess the problem is with:

    .hasClass(&#39;:not(.closedTab)&#39;);

What is the problem?

My purpose is to create my own accordion (without using jQuery UI)

and I am trying to write it like this:

	$(&#39;#sitesAccordion .groupOfSites&#39;).click(function() {

        //Get the last opened tab
        var lastOpenSite = $(this).siblings().hasClass(&#39;:not(.closedTab)&#39;);

        //Close last opened tab and add class
        lastOpenSite.hide().toggleClass(&#39;closedTab&#39;);
        
        //Open the current Tab
        $(this).children(&#39;.accordionContent&#39;).toggle(&#39;fast&#39;);

        // remove class from open tab
        $(this).toggleClass(&#39;closedTab&#39;);


	});

Is this the best way?

Is it possible to load an external font via inline CSS?

Note: I&#39;m *not* talking about using an external CSS file with a `@font-face` definition, but rather something like the following:

    &lt;h1 style=&quot;font-family:myfont;

and in jquery:

    for(i=0;i&lt;3;i++){
        $(&#39;#here_table&#39;).append( &#39;result&#39; +  i );
    }

this generating for me:

    &lt;div id=&quot;here_table&quot;&gt;
        result1 result2 result3 etc
    &lt;/div&gt;

I would like receive this in table:

    }

     $(&#39;#here_table&#39;).append(  &#39;&lt;/table&gt;&#39; );

What is the difference between class and instance variables in Python?

    class Complex:
        a = 1

and

    class Complex:
        def __init__(self):
            self.a = 1

Using the call: `x = Complex().a` in both cases assigns x to 1.

A more in-depth answer about `__init__()` and `self` will be appreciated.

What is the difference between class and instance variables?

Let&#39;s say I&#39;m creating a class for a binary tree, `BT`, and I have a class which describes an element of the tree, `BE`, something like 

    template&lt;class T&gt; class BE {
        T *data;
        BE *l, *r;
    public:
    ...
        template&lt;class U&gt; friend class BT;
    };

    template&lt;class T&gt; class BT {
        BE&lt;T&gt; *root;
    public:
    ...
    private:
    ...
    };

This appears to work; however I have questions about what&#39;s going on underneath. 

I originally tried to declare the friend as

    template&lt;class T&gt; friend class BT;

however it appears necessary to use `U` (or something other than `T`) here, why is this? Does it imply that any particular `BT` is friend to any particular `BE` class? 

The IBM page on templates and friends has examples of different type of friend relationships for functions but not classes (and guessing a syntax hasn&#39;t converged on the solution yet). I would prefer to understand how to get the specifications correct for the type of friend relationship I wish to define. 

Class template with template class friend, what&#39;s really going on here?

I need to call the `initialize` method of the parent class, from inside the inherited `MyModel`-class, instead of completely overwriting it as I am doing today.

How could I do this?

Here&#39;s what my code looks right now:

    BaseModel = Backbone.Model.extend({
        initialize: function(attributes, options) {
            // Do parent stuff stuff
        }
    });
    
    MyModel = BaseModel.extend({
    	initialize: function() {
    	    // Invoke BaseModel.initialize();
            // Continue doing specific stuff for this child-class.
    	},
    });

Accessing parent class in Backbone

I have renamed a python class that is part of a library. I am willing to leave a possibility to use its previous name for some time but would like to warn user that it&#39;s deprecated and will be removed in the future.

I think that to provide backward compatibility it will be enough to use an alias like that:

    class NewClsName:
        pass

    OldClsName = NewClsName

I have no idea how to mark the `OldClsName` as deprecated in an elegant way. Maybe I could make `OldClsName` a function which emits a warning (to logs) and constructs the `NewClsName` object from its parameters (using `*args` and `**kvargs`) but it doesn&#39;t seem elegant enough (or maybe it is?).

However, I don&#39;t know how Python standard library deprecation warnings work. I imagine that there may be some nice magic to deal with deprecation, e.g. allowing treating it as errors or silencing depending on some interpreter&#39;s command line option.

The question is: How to warn users about using an obsolete class alias (or obsolete class in general).

**EDIT**: The function approach doesn&#39;t work for me (I already gave it a try) because the class has some class methods (factory methods) which can&#39;t be called when the `OldClsName` is defined as a function. Following code won&#39;t work:

    class NewClsName(object):
        @classmethod
        def CreateVariant1( cls, ... ):
            pass

        @classmethod
        def CreateVariant2( cls, ... ):
            pass

    def OldClsName(*args, **kwargs):
        warnings.warn(&quot;The &#39;OldClsName&#39; class was renamed [...]&quot;,
                      DeprecationWarning )
        return NewClsName(*args, **kwargs)

    OldClsName.CreateVariant1( ... )

Because of:

    AttributeError: &#39;function&#39; object has no attribute &#39;CreateVariant1&#39;

Is inheritance my only option? To be honest, it doesn&#39;t look very clean to me - it affects class hierarchy through introduction of unnecessary derivation. Additionally, `OldClsName is not NewClsName` what is not an issue in most cases but may be a problem in case of poorly written code using the library.

I could also create a dummy, unrelated `OldClsName` class and implement a constructor as well as wrappers for all class methods in it, but it is even worse solution, in my opinion.

How to warn about class (name) deprecation

I noticed that in Python, people initialize their class attributes in two different ways.

The first way is like this:

    class MyClass:
      __element1 = 123
      __element2 = &quot;this is Africa&quot;
    
      def __init__(self):
        #pass or something else

The other style looks like:

    class MyClass:
      def __init__(self):
        self.__element1 = 123
        self.__element2 = &quot;this is Africa&quot;

Which is the correct way to initialize class attributes?
