just this as img tag is a content element

    img {
        content:url(http://example.com/image.png);
    }



    #divID {
        background-image: url(&quot;http://imageurlhere.com&quot;);
        background-repeat: no-repeat;
        width: auto; /*or your image&#39;s width*/
        height: auto; /*or your image&#39;s height*/
        margin: 0;
        padding: 0;
    }

No there isn&#39;t. You can specify a background image but that&#39;s *not* the same thing.

CSS is not used to define values to DOM element attributes, javascript would be more suitable for this.

No. The closest you can get is setting a background image:

    &lt;div id=&quot;myimage&quot;&gt;&lt;/div&gt;
    
    #myimage {
      width: 20px;
      height: 20px;
      background: white url(myimage.gif) no-repeat;
    }

After trying these solutions I still wasn&#39;t satisfied but I found a solution in this [article](http://css-tricks.com/replace-the-image-in-an-img-with-css/) and it works in Chrome, Firefox, Opera, Safari, IE8+

    #divId {
    
      display: block;
      -moz-box-sizing: border-box;
      box-sizing: border-box;
      background: url(http://notrealdomain2.com/newbanner.png) no-repeat;
      width: 180px; /* Width of new image */
      height: 236px; /* Height of new image */
      padding-left: 180px; /* Equal to width of new image */
    
    }

They are right. IMG is a content element and CSS is about design.
But, how about when you use some content elements or properties for design purposes?
I have IMG across my web pages that must change if i change the style (the CSS).

Well this is a solution for defining IMG presentation (no really the image) in CSS style.&lt;br/&gt;
1: create a 1x1 transparent gif or png.&lt;br/&gt;
2: Assign propery &quot;src&quot; of IMG to that image.&lt;br/&gt;
3: Define final presentation with &quot;background-image&quot; in the CSS style.&lt;br/&gt;

It works like a charm :)

I am trying to create some script variables in T-SQL as follows:

        GO

        SET NUMERIC_ROUNDABORT OFF;
        
        
        GO
        :setvar DatabaseName &quot;MesProduction_Preloaded_KLM_MesSap&quot;

However, when I run this, I get an error stating &#39;Incorrect syntax near &#39;:&#39;. What am I doing wrong?

I have a header div as the first element in my wrapper div, but when I add a top margin to a h1 inside the header div it pushes the entire header div down. I realize this happens whenever I apply a top margin to the first visible element on a page. 

Here is a sample code snippet. Thanks!

&lt;!-- begin snippet: js hide: false --&gt;

&lt;!-- language: lang-css --&gt;

    div#header{
    	width: 100%;
    	background-color: #eee;
    	position: relative;
    }
    
    div#header h1{
    	text-align: center;
    	width: 375px;
    	height: 50px;
    	margin: 50px auto;
    	font-size: 220%;
    	background: url(&#39;../../images/name_logo.png&#39;) no-repeat;
    }

&lt;!-- language: lang-html --&gt;

I&#39;m looking for a **HTML** or **ASCII** character which is a triangle pointing up or down so that I can use it as a toggle switch.

I found &amp;uarr; (`&amp;uarr;`), and &amp;darr; (`&amp;darr;`) - but those have a narrow stem. I&#39;m looking just for the HTML arrow &quot;head&quot;.

How to line-break from css, without using &lt;br /&gt;?

My understanding is that mime types are set by the web server. Why do we add the `type=&quot;text/javascript` or `type=&quot;text/css&quot;` attribute? Isn&#39;t this a useless and ignored attribute?

Why write &lt;script type=&quot;text/javascript&quot;&gt; when the mime type is set by the server?

My searches keep turning up only guides explaining how to use and apply attributes to a class.  I want to learn how to create my own attribute classes and the mechanics of how they work.

**How are attribute classes instantiated?**  Are they instantiated when the class they are applied to is instantiated?  Is one instantiated for each class instantiated that it is applied to?  E.g. if I apply the SerializableAttribute class to a MyData class, and I instantiate 5 MyData instances, will there be 5 instances of the SerializbleAttribute class created behind the scenes?  Or is there just one instance shared between all of them?

**How do attribute class instances access the class they are associated with?**  How does a SerializableAttribute class access the class it is applied to so that it can serialize it&#39;s data?  Does it have some sort of SerializableAttribute.ThisIsTheInstanceIAmAppliedTo property? :)   Or does it work in the reverse direction that whenever I serialize something, the Serialize function I pass the MyClass instance to will reflectively go through the Attributes and find the SerialiableAttribute instance?

How do attribute classes work?

I want to create a dynamic object (inside another object) in Python and then add attributes to it.

I tried:

    obj = someobject
    obj.a = object()
    setattr(obj.a, &#39;somefield&#39;, &#39;somevalue&#39;)

but this didn&#39;t work.

Any ideas?

*edit:*

I am setting the attributes from a `for` loop which loops through a list of values, e.g.

    params = [&#39;attr1&#39;, &#39;attr2&#39;, &#39;attr3&#39;]
    obj = someobject
    obj.a = object()

    for p in params:
       obj.a.p # where p comes from for loop variable
 

In the above example I would get `obj.a.attr1`, `obj.a.attr2`, `obj.a.attr3`.  

I used the `setattr` function because I didn&#39;t know how to do `obj.a.NAME` from a `for` loop.

How would I set the attribute based on the value of `p` in the example above?


How can I create an object and add attributes to it?

It is really unbelievable but real. This code will not work:

    [AttributeUsage(AttributeTargets.Property|AttributeTargets.Field)]
    public class Range : Attribute
    {
        public decimal Max { get; set; }
        public decimal Min { get; set; }
    }
    
    public class Item
    {
        [Range(Min=0m,Max=1000m)]  //compile error:&#39;Min&#39; is not a valid named attribute argument because it is not a valid attribute parameter type 
        public decimal Total { get; set; }  
    }
While this works:

    [AttributeUsage(AttributeTargets.Property|AttributeTargets.Field)]
    public class Range : Attribute
    {
        public double Max { get; set; }
        public double Min { get; set; }
    }
    
    public class Item
    {
        [Range(Min=0d,Max=1000d)]
        public decimal Total { get; set; }  
    }
Who can tell me why double is OK while decimal is not.

Why &quot;decimal&quot; is not a valid attribute parameter type?

How can I achieve such job:

    def get_foo(someobject, foostring):
        return someobject.foostring

IE:

if I do `get_foo(obj, &quot;name&quot;)` it should be calling `obj.name` (see input as string but I call it as an attritube.

Thanks

How to make an app&#39;s background image repeat

I&#39;m developing an app for Android 2.1 upwards.  I want to enable my users to select a profile picture within my app (I&#39;m not using the contacts framework). 

The ideal solution would be to fire an intent that enables the user to select an image from the gallery, but if an appropriate image is not available then use the camera to take a picture (or vice-versa i.e. allow user to take picture but if they know they already have a suitable image already, let them drop into the gallery and pick said image).

Currently I can do one or the other but not both.

If I go directly into camera mode using MediaStore.ACTION_IMAGE_CAPTURE then there is no option to drop into the gallery.  

If I go directly to the gallery using Intent.ACTION_PICK then I can pick an image but if I click the camera button (in top right hand corner of gallery) then a new camera intent is fired. So, any picture that is taken is not returned directly to my application. (Sure you can press the back button to drop back into the gallery and select image from there but this is an extra unnecessary step and is not at all intuitive).

So is there a way to combine both or am I going to have to offer a menu to do one or the other from within my application?  Seems like it would be a common use case...surely I&#39;m missing something?

In this scenario, the image file is not linked to from the HTML, but rather the image data is embedded in the HTML itself.
