What is HTML

HTML is a Markup Language for creating Web pages.

Description

HTML stands for HyperText Markup Language. It is used to create Web pages. That is, Web pages all over the world consist of HTML.
We can look at how other people have coded their Web pages. Click on the "View" menu and then on "Source".

<!doctype html>

<head>

<title>Sample Web page</title>

</head>

<body>

<p>Here is a paragraph</p>

</body>

</html>

History

The HyperText Markup Language (HTML) is the publishing language of the World Wide Web. The first version of HTML was described by Tim Berners-Lee in late 1991. For its first five years (1990-1995), HTML went through a number of revisions and experienced a number of extensions, primarily hosted first at CERN, and then at the IETF.

With the creation of the W3C, HTML's development changed venue again. A first abortive attempt at extending HTML in 1995 known as HTML 3.0 then made way to a more pragmatic approach known as HTML 3.2, which was completed in 1997. HTML4 followed, reaching completion in 1998.

Version	Published year
HTML+	1993
HTML2.0	1995
HTML3.2	1997
HTML4.01	1999

Tag

HTML uses markup tags to create Web pages. All content on the Web page is meant by tag. For examples, "Here is a paragraph", "This is a image" and so on.

Tag syntax

HTML is using tags for its syntax. A tag is composed with special characters: <, > and /. They are interpreted by softwares to compose an HTML element.

Decomposition of HTML elements

HTML Elements comes usually by tag pairs.

For opening a simple element with a start tag

it starts with <
then a list of characters without space, the tagname (or element)
ends usually with a >.

Then closing the simple element with a end tag

it starts with </
then the same list of characters without space, the tagname (or element)
ends usually with a >.

If the tagname is "cite", then you get

Some elements do not have an end tag (because they are implied by the following tags). For example you might have seen.

<br>

An element can have attributes to refine its meaning.

These attributes are specified on the start tag. They consist of a name and a value, separated by an "=" character. Such as:

In HTML, the attribute value can remain unquoted if it doesn't contain spaces or any of the following characters: " ' ` = < or >. Otherwise, it has to be quoted using either single or double quotes. The value, along with the "=" character, can be omitted altogether if the value is the empty string. Once you are working in a team you might want to choose a common way of authoring your code.

These are examples of syntaxes you might see on the Web:

The following tags have been introduced for better structure:

· section: This tag represents a generic document or application section. It can be used together with h1-h6 to indicate the document structure.

· article: This tag represents an independent piece of content of a document, such as a blog entry or newspaper article.

· aside: This tag represents a piece of content that is only slightly related to the rest of the page.

· header: This tag represents the header of a section.

· footer: This tag represents a footer for a section and can contain information about the author, copyright information, et cetera.

· nav: This tag represents a section of the document intended for navigation.

· dialog: This tag can be used to mark up a conversation.

· figure: This tag can be used to associate a caption together with some embedded content, such as a graphic or video.

Creating dynamic gallery

Opacity range (0-1) (0.1,0.2,0.3 etc)

Help of the opacity we can generate the transparent form content our contender. The opacity value we can specify between 0 to 1. 1 is full colour and 0 is full transparency.

Syntax:- opacity(0.5)

Transition:-we can use the transition attributes and properties create a sequence movement between two positions of the objects. The position distance how much time to finish to specify in the help of the seconds.

In the transition it is possible to specify delay time also.

Delay time to specify below

-liner (starting to ending same motion)

-easy-in (starting it slow ending in speed.)

-easy-out(starting in speed ending in slow)

Help of the java script we can see the particular output in the webpage or website by using a particular condition. The javascript we can write in various methods. They are :

Inline script, internal script and external script.

Inline Script:- the script we can write in an element, what are the function we are defining inline, the function it work in single element.

Internal Script:- what are the script we define in internal format the script we can use only defining page.

function here

</script>

External script:- what are the script we are defining in the external the script we can use more than one page.

Basic Features in JavaScript

-structure of the java script

-defining variables

-using operators

-define functions

-using events

-display dialog box
