What is HTML validation?

psuresh1982- Member Since Sep-2006 | Oct 24th, 2007
It means checks the markup validity of Web documents in HTML
Markup Validity:However, Just as texts in a natural language can include spelling or grammar errors, documents using Markup languages may (for various reasons) not be following these rules. The process of verifying whether a document actually follows the rules for the language(s) it uses is called validation, and the tool used for that is a validator. A document that passes this process with success is called valid.
With these concepts in mind, we can define "markup validation" as the process of checking a Web document against the grammar (generally a DTD) it claims to be using.

Netscape offers <LAYER> tag incorporated with JavaScript and Style Sheets as the way to get control on positioning, while Microsoft use ActiveX and CSS Style Sheets incorporated with scripting language like JScript (Microsoft's version of JavaScript) or VBScript to control positioning.
Both share the same concept of positioning in which the coordinates x, y, and z can be specified. Z (z-axis) will allow designers to define the order of elements -- in front of or behind other object. Designers now can get control over the positioning.jnaneswarisd

The SPAN having notation as
<SPAN> </SPAN>
is used for highlighting text of any color desired, for adding colored text, for adding background image to text. SPAN doesn't cause a line break. It delimits text and it allows styles to be applied to a 'elemental' region, or for the 'elemental' region to be identified, without causing a break in the text flow.RajivPrasad

This depends on what kind of video. If it is a standard AVI video, you could use the EMBED tag.
For example:
<embed src="video_path.avi" width="300" height="300"></embed>
You may change the width and the height. This will work exacly the same for flash movies.haz_bo

suji- Member Since Sep-2005 | Apr 3rd, 2011
iframe is used for creating an inline or floating frame. As most of know frames are mainly used to structure the page or for placing a menu bar on the side and so on. But iframe is used in a different context. That is in other words <iframe> is used to embed or insert content on a page of padding. This is done for several reasons. Say the content may be large enough that the user may wish to place it separately and scroll through it. There are many attributes present in <iframe> and some of the attributes used with <iframe> are namely:
NAME:
Used for specifying the name of the frame.
SCROLL:
Used for specifying the scrolling action to be activated. Can take three values namely AUTO, YES or NO. AUTO will allow the browser to take the decision and activate scroll bar when needed YES specify scroll bar is needed and NO specifies scroll bar is not needed.
ALIGN:
This is used for alignment of text and the values that can be taken by it are namely LEFT, RIGHT, TOP, MIDDLE, and BOTTOM.
FRAMEBORDER:
Used for setting borders, around the frames if needed. A value of 1 set the border around the frame and 0 specify for no border.
HEIGHT:
Used to specify the height of the frame and this value is mentioned in pixels.
HSPACE:
Used for specifying horizontal spacing around the frames.dinesh
