3. HTML is a computer language devised to allow website
creation
Firstly mentioned on the Internet by Berners-Lee in late
1991.
HTML stands for Hyper Text Markup Language .
• An HTML file is a text file containing small markup tags .
• The markup tags tell the Web browser how to display the
page .
• An HTML file must have an htm or html file extension
Example : Simple HTML Page Example Explained The first
tag in your HTML document is <html>.
4. HTML tags have two main types: block-level and
inline tags.
Block-level elements take up the full available
space and always start a new line in the document.
Headings and paragraphs are a great example of
block tags.
Inline elements only take up as much space as they
need and don’t start a new line on the page. They
usually serve to format the inner contents of block-
level elements. Links and emphasized strings are
good examples of inline tags.
5. BASIC TAG OF HTML-
<HTML> -Defines an HTML document
<HEAD> -Defines<TITLE> -Defines
<BODY> -Defines the document’s body
<b>
Tag Attributes Tags can have attributes. Attributes
provide additional information to an HTMLelement:-
<table>.
Quote Attribute - quotes: name='Digi Corp
"Information" Systems' .
6. <h1> to <h6> - Make a line or a particular
word as a heading.
<p> - to make the text appears as it
is written in the form of
paragraph.
<br> - Tag is used when we want to
don't want to start a new paragraph.
<hr> - Defines a horizontal rule .

The next iteration of HTML has been met with
excitement by some, loathing by others and
confusion/fear by everyone else.
The main focus areas are :
1. New E lements
2. Semantic Changes
3. Getting it Working Today
10. HTML5 includes several new APIs that are integrated with some
of the new HTML5 elements.

11. New Elements in HTML5:

<aside>Definessomecontentasidefromthearticleitisplaced in.
<audio>Definessound, suchasmusicorotheraudiostreams.
<canvas>Definesgraphic,suchasgraphsorotherimages.
<command>Definesacommandbutton,likearadiobutton,acheckbox,ora
button.
12. <datagrid> Defines a list of selectable data. The
datagrid is displayed as a tree-list
<datalist> Defines a list of selectable data. Use this
element together with the input element, to make a
dropdown list for the input’s value
<details> Defines details of an element, which the user
can see, and click to hide
13. <dialog> - Defines a dialog, such as a
conversation .
<nav> - Defines a section of navigation
links
<nest> - Defines a nesting point in a data
template for child elements. Used together with
the elements <datatemplate> and <rule>
<source> - Defines media resources for media
elements, such as video and audio
<time> - Defines a time or a date, or both
<video> - Defines video, such as a movie clip
or other video streams
14. Semantic Changes
This is the part that should fundamentally change
the way you structure your sites. These six
elements are:
1. <nav>
2. <section>
3. <article>
4. <header>
5. <footer>
6. <aside>
15. Getting HTML5Working Today::
As any goodweb developer knows, all the major web
browsers still differ (some are worse than others, you
know who I’m talking about) on support for HTML4.01 and
XHTML 1.0.
Though mega-developers like Google are pushing along
the acceptance of HTML5, it won’t be supported across
the board for some time.
16. Conclusion –
Introduced the new elements and APIs included in
HTML5.
We also got a taste of the semantic changes to
come and the new structure our web pages should
take in the future.
Finally, we learned that even though HTML5 isn’t
quite ready for the masses, we can still get our
grubby developer fingers on it and start
experimenting today.
