In CSS, classes allow you to apply a style to a given class of an element. To do this, you link the element to the style by declaring a style for the class, then assigning that class to the element. CSS Class Syntax You declare a CSS class by using a dot (.) followed by the class name. You make up the class name yourself. After the class name you simply enter the properties/values that you want to assign to your class. .class-name { property:value; } If you want to use the same class name for multiple elements, but each with a different style, you can prefix the dot with the HTML element name. html-element-name.class-name { property:value; } You can also select elements (or classes) that's nested within another element or class. For example, div.css-section p will select all elements that are nested within a <div> element that uses the .css-section class. One major benefit of doing this is that you don't need to apply a class to every instance of an ele

The navigation drawer is a panel that transitions in from the left edge of the screen and displays the app’s main navigation options.The user can bring the navigation drawer onto the screen by swiping from the left edge of the screen or by touching the application icon on the action bar.As the navigation drawer expands, it overlays the content but not the action bar. When the drawer is fully extended, the action bar adjusts its content by replacing the current action bar title with the app name and removing all actions that are contextual to the view underneath the navigation drawer. The overflow menu with the standard action items for Settings and Help remains visible. read more from here...

This example shows you how to load large images in the gridview without any lag or without outofmemory error. This sample application uses the LruCache to hold the images. A cache that holds strong references to a limited number of values. Each time a value is accessed, it is moved to the head of a queue. When a value is added to a full cache, the value at the end of that queue is evicted and may become eligible for garbage collection. Read more from here. http://developer.android.com/reference/android/util/LruCache.html This is the MainActivity that holds the GridView. We are adding here 100 images in the Grid to load. This time I am loading images from the resources. MainActivity.java import java.util.ArrayList; import android.app.Activity; import android.os.Bundle; import android.widget.GridView; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

Solution 1 : You can set the Background property of this Grid control to an ImageBrush. <Grid.Background> </Grid.Background> Solution 2 : Set Grid.Background property in the LayoutRootStyle. Instead of setting the Grid.Background property in each page you can also set it once in the 'LayoutRootStyle' style. The All my pages have this style set on the root Grid control. This style is defined in the 'StandardStyles.xaml' which can be found in the 'Common' folder. The 'Background' property of the style is set to the 'ApplicationPageBackgroundThemeBrush' static resource which makes it black. You have to replace it with the ImageBrush. <Style x:Key="LayoutRootStyle" TargetType="Panel"> </Setter>

Here we will talk about the purpose and nature of XAML, comparing it to C# This works almost as HTML XAML is a special usage of XML. XAML has something to do with defining a user interface in our Phone's interface. So in that regard, it feels very much like HTML. But there’s a big difference … XAML is actually used to create instances of classes and set the values of the properties. So, for example, I'm defining a Button control in XAML: <Button Name = "Sample" Width="200" Height="200" HorizontalAlignment="Left" Verticalalignment="Top" Background="Red" Click="Sample_Click" > </Button>

We have heard a plenty of rumours about the upcoming iPhone, one most common rumor about the iPhone 6 is that it will feature a larger display and the upcoming iOS 8. These rumors sound promising as the current trend in smartphones is having a larger display. We have seen smartphones with display as large as 6.8-inches, that’s close to the size of a tablet. Smartphones with 5.5-inch and 6-inch display has now become common, and thus to keep up with the competition Apple must adopt the large display concept on its iPhone series of phones. Apple was stuck to its philosophy of one hand usage and stayed away from making bigger phones, last year however Apple moved one step ahead and increased the display size from 3.5-inches to 4-inches. With that 4-inch display on iPhone 5 and iPhone 5c, Apple increased the length of the display and maintained the same breadth of the phone. But now its time Apple make some software innovation to serve single hand usage and increase the display size to

Static member is a member that belongs to the class and not to the objects of the class. Static members are specified using the keyword static. The three valid static members of a class are static constructor, static variable and static method. Static Variables: When a variable or attribute of a class is declared as static then it is called as Static Variable. Only one copy of static variable will be stored in the memory. All the objects of the class will be accessing the same copy of it. Static Methods: Static methods are the methods which are marked as static. Static method can access only static members of a class. Static methods cannot access non-static or instance members of a class. Static Constructors: Static constructors are special type of constructors that are called when the class is loaded for the first time. Static constructors are used to initialize static variables of a class.

Constructor is specialized method that is contained in a class. Constructor will be triggered automatically when an object is created. Purpose of the Constructors is to initialize an object of a class. Constructor’s name is identical to the Class name. Constructors can take parameters but constructors have no return type. This is because; constructors return an object by itself. Static Constructor When a constructor of a class is marked with static modifier, then the constructor is called static constructor. Unlike other constructors, Static constructor cannot be triggered while creating instances of that class. Static constructors will be automatically triggered when the class is loaded for the first time. Static constructors are used to initialize values for the static variables of that class.

Google Glass is getting glasses. Google is adding prescription frames and new styles of detachable sunglasses to its computerized, internet-connected goggles known as Glass.
