HTML Iframes
An iframe is used to display a web page within a
web page.
Syntax for adding an iframe:
<iframe src="URL"></iframe>
The URL points to the location of the separate page.
Iframe - Set Height and Width
The height and width attributes are used to specify
the height and width of the iframe.
The attribute values are specified in pixels by
default, but they can also be in percent (like
"80%").
Iframe - Set Height and Width
Example :
<!DOCTYPE html>
<html>
<body>
<iframe src="http://www.detik.com/" width="500“ height="200"></iframe>
<p>Some older browsers don't support iframes.</p>
<p>If they don't, the iframe will not be visible.</p>
</body>
</html>

Results :
Iframe - Remove the Border
The frameborder attribute specifies whether or not
to display a border around the iframe.
Set the attribute value to "0" to remove the border:
Example :
<iframe src="demo_iframe.htm"
frameborder="0"></iframe>

The HTML <script> Tag
JavaScripts make HTML pages more dynamic and
interactive.
The <script> tag is used to define a client-side
script, such as a JavaScript.
The <script> element either contains scripting
statements or it points to an external script file
through the src attribute.
The required type attribute specifies the MIME type
of the script.
The HTML <script> Tag
Common uses for JavaScript are image manipulation, form validation, and dynamic changes of content.
The script below writes Hello World! to the HTML output:
Example :
<script> document.write("Hello World!") </script>
The HTML <noscript> Tag
The <noscript> tag is used to provide an alternate content for users that have disabled scripts in their browser or have a browser that doesn’t support client-side scripting.
The <noscript> element can contain all the elements that you can find inside the <body> element of a normal HTML page.
The content inside the <noscript> element will only be displayed if scripts are not supported, or are disabled in the user’s browser:
Example :
<script> document.write("Hello World!") </script> <noscript>Sorry, your browser does not support JavaScript!</noscript>
JavaScript Examples
<!DOCTYPE html>
<html>
<body>
<h1>My First JavaScript</h1>
<p id="demo">
JavaScript can change the style of an HTML element.
</p>
<script>
function myFunction()
{
x=document.getElementById("demo") // Find the element
x.style.color="#ff0000"; // Change the style
}
</script>
<button type="button" onclick="myFunction()">Click Me!</button>
</body>
</html>
JavaScript Examples
The Results :
Video on the Web
Until now, there has not been a standard for
showing a video/movie on a web page.
Today, most videos are shown through a plug-in (like
flash). However, different browsers may have
different plug-ins.
HTML5 defines a new element which specifies a
standard way to embed a video/movie on a web
page: the <video> element.
Browser Support
Internet Explorer 9+, Firefox, Opera, Chrome, and
Safari support the <video> element.
Note: Internet Explorer 8 and earlier versions, do
not support the <video> element.
HTML5 Video - How It Works
To show a video in HTML5, this is all you need:
Example :
<video width="320" height="240" controls>
<source src="movie.mp4" type="video/mp4">
<source src="movie.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>
HTML5 Video - How It Works
The control attribute adds video controls, like play, pause, and volume.
It is also a good idea to always include width and height attributes. If height and width are set, the space required for the video is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the video, and cannot reserve the appropriate space to it. The effect will be that the page layout will change during loading (while the video loads).
You should also insert text content between the <video> and </video> tags for browsers that do not support the <video> element.
The <video> element allows multiple <source> elements. <source> elements can link to different video files. The browser will use the first recognized format.

Audio on the Web
Until now, there has not been a standard for
playing audio files on a web page.
Today, most audio files are played through a plug-
in (like flash). However, different browsers may
have different plug-ins.
HTML5 defines a new element which specifies a
standard way to embed an audio file on a web
page: the <audio> element.
Browser Support
Internet Explorer 9+, Firefox, Opera, Chrome, and
Safari support the <video> element.
Note: Internet Explorer 8 and earlier versions, do
not support the <video> element.
HTML5 Audio - How It Works
To play an audio file in HTML5, this is all you need:
Example :
<audio controls>
<source src="horse.ogg" type="audio/ogg">
<source src="horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
HTML5 Audio
The control attribute adds audio controls, like play,

You should also insert text content between the
<audio> and </audio> tags for browsers that do
not support the <audio> element.
The <audio> element allows multiple <source>
elements. <source> elements can link to different
audio files. The browser will use the first recognized
