What is HTML

HTML was invented in 1990 by a scientist called Tim Berners-Lee. It stands for "Hyper Text Markup Language" and is the main markup language for creating web pages and other information that can be displayed in a web browser.

Start creating HTML5 features in Netbeans IDE

The following is the procedure we need to follow.

Step 1

Open the Netbeans IDE.

Step 2

Now go to "File Menu" then select "New Project" as in the following.

Fig-2.jpg

Step 3

Now choose "HTML5" -> "HTML5 Application" as in the following figure.

Fig-3.jpg

Step 4

Click on "Next". Then a new window is generated. Provide your project name there as shown in the following figure.

Fig-4.jpg

Step 5

Click on "Finish". Your project is generated with a default "index.html" as in the following figure.

Fig-5.jpg

Now add some media components to show the benefits of HTML5's new features.

Step 6

In this step we show how to play video in HTML5. First add a video file (as I added "nature.mp4") in your project window. Now you need to modify the "index.html" file as from the following code.

<!DOCTYPE html>

 <html>

  <body>

   <video width="700" height="400" controls autoplay>

   <source src="nature.mp4" type="video/mp4">

   <source src="nature.ogg" type="video/ogg">

   If it is not played try to run this code in different browser!

  </video>

 </body>

</html>

Step 7

Run your project and ensure that the video is playing. You will see the output as in the following figure . While running, set your browser information; if you are using the Chrome browser then you need to add the extension "Netbeans Connector" and then run your file.

Step 8

Now create a new HTML file in which we show how to play audio using HTML5 in the Netbeans IDE. Right Click on the project then choose "New" -> "HTML File" as in the following.

Step 9

Now add an audio file (I added the file "TuHiKhwahish.mp3") to your project menu and write the following code in your new HTML file.

<!DOCTYPE html>

<html>

<audio controls autoplay>

  <source src="TuHiKhwahish.ogg" type="audio/ogg">

  <source src="TuHiKhwahish.mp3" type="audio/mpeg">

If it is not played then run in different browser.

</audio>

</html>

Step 10

Now run your new file (I added the file "AudioFile.html"); the following output is generated.

Step 11

Now create another HTML file to play video directly from Youtube. Provide the name as "Youtubeplay" and write the following codefor it.

<!DOCTYPE html>

<html><embed

width="600" height="350"

src="https://www.youtube.com/v/phzKG-Y-SI8"

type="application/x-shockwave-flash">

</embed>

<html>

fig-11.jpg

Step 12

Now run your file ("Youtubeplay.html"); you will see that your video is directly played through Youtube as in the following.

fig-12.jpg

Now click on the play button; your video will start playing as in the following.

Now create a Geo-location to find user location.

Step 13

Now create a new HTML file named "ShowUserLocation" and write the following code:

<!DOCTYPE html>

<html>

<body>

<p id="user">Click on the display button to find out your positions:</p>

<button onclick="findLocation()">Click To Find Your Position</button>

<script>

var i=document.getElementById("user");

Function findLocation()

  {

    If (navigator.geolocation) Then

    {

    navigator.geolocation.getCurrentPosition(givePosition);

    }

  else{i.innerHTML="This function is not worked in your browser. Please try it in another Browser.";}

  }

function givePosition(findposition)

  {

  i.innerHTML="Latitude: " + findposition.coords.latitude +

  "<br>Longitude: " + findposition.coords.longitude;  

  }

</script>

</body>

</html>

Step 14

Now run your file and see that same output as below.

fig-15.jpg

Now click on "Click To Find Your Position Button" and see your location there. It appears as in the following, with my location shown.
