December 24, HTML 4. It offers the same three variations as HTML 4. It expired in May The draft was considered very large at pages web programming html the pace of browser development, as well as the number of interested parties, had outstripped the resources of the IETF.
These included extensions to control stylistic aspects of documents, contrary to the "belief [of the academic engineering community] that such things as text color, background texture, font size web programming html font face were definitely outside the scope of a language when their only intent was to specify how a document would be organized.
In Maythe working group advanced HTML5 to "Last Call", an invitation to communities web programming html and outside W3C to confirm the technical soundness of the specification.
When it is used on a web programming html loaded document, it will replace the whole document by the given HTML, which is usually not what you want. The idea is to have a script call it while the document is being loaded, in which case the written HTML will be inserted into the document at the place of the script tag that web programming html it.

This is a simple way to add some dynamic elements to a page. For example, here is a trivially simple document showing the current time.
In case you are not quite sure what the role of 'forms' is, let me give a quick summary. When this file is not really a passive file, but a server-side program, it can become useful to include information other than a filename in the web programming html.
For this purpose, HTTP requests are allowed to contain additional 'parameters'. Here is an example: This request has one parameter, called q for 'query', presumablywhose value is aztec empire. There are a number of characters that can not occur in these values, such as spaces, ampersands, or question marks.

When the submit button is clicked, or enter is pressed, the information that was entered in the fields is added to this action Web programming html as parameters, and the browser will request this URL.
The names of the fields determine the names of the HTTP parameters that are used to store their values. Sending this form might produce a URL like this: There is an alternative method for sending parameters, which is called post. A form using the post method puts the values of its parameters in this data block web programming html of in the URL.
But the difference between the two methods is not just a question of convenience. Traditionally, get requests are used for requests that just ask the server for some document, while post requests are used to take an action that changes something on the server. For example, getting a list of recent messages on an Internet forum would be a get request, while adding a web programming html message would be a post web programming html.
If changes to a site can be made by get requests, these well-meaning 'crawlers' could do all kinds of damage.

This opens up possibilities for all kinds of tricks, such as checking values before they are sent to the server, or automatically filling in certain fields. Relative URLs are interpreted by the browser to refer to files on the same server as the current document. For instance, the following HTML fragment is confusing to a web programming html because the two elements are intermingled: All other elements are called inline elements.
Some tags are self-closing, e. Some tags allows us to define web programming html attributes for the elements, e.
