- 3. HTML isa 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 tagshave 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.

- 11. New Elements inHTML5: HTML5introducesquiteafewnewelements. <article>Definesexternalcontent. <aside>Definessomecontentasidefromthearticleitisplaced in. <audio>Definessound, suchasmusicorotheraudiostreams. <canvas>Definesgraphic,suchasgraphsorotherimages. <command>Definesacommandbutton,likearadiobutton,acheckbox,ora button.
- 12. <datagrid> Definesa 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

- 15. Getting HTML5WorkingToday:: 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 – Introducedthe 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.
