3. Features : block structure
Block structure :
<article> <section> <aside> <header> <footer> <nav>
<article>
Represents a component of a page that consists of a self-contained composition in a document,
page, application, or site and that is intended to be independently distributable or reusable. This
could be a forum post, blog post, newspaper article, a user comment, or any other independent
item of content.
<section>
Is a generic document or application section. However, this isn’t a replacement for the div element.
A section is only appropriate if the element’s contents would be listed explicitly in the document’s
outline.
<aside>
Is used to represent a section of content that is related to the content around the aside element, eg
a pull quote or a sidebar.
4. Features : block structure cont
Block structure :
<article> <section> <aside> <header> <footer> <nav>
<header>
Represents a group of navigational aids, and is used to construct the document outline. You are also
not restricted to using header only once; you could use this to mark up the author’s name and the
time of a comment placed on a blog post, for example.
<footer>
Is the footer to a section. This is not restricted to one use at the bottom of the page. You can also
use the footer to mark up the footer of a blog post in addition to the footer of the entire document.
<nav>
Is used to wrap major navigation blocks, such as table of contents, pagination links and
breadcrumbs. Note that the nav element should be used for links that navigate around site, i.e.
inappropriate for a list of sponsor links.
5. Features : interactive elements
INTERACTIVE ELEMENTS:
<video> <audio> <canvas> <source>
<video> and <audio>
Are types of media elements. They enable you to embed audio and video directly into the browser
without any need for plug-ins. No longer having to rely on Flash. You can either let the browser
render the chrome for the element, or take control via JavaScript to create a bespoke interface.
<source>
Is a child element to audio and video. It enables you to specify multiple alternative sources for the
media element.
<canvas>
is a 2D drawing element that can be accessed using JavaScript to render graphics on the fly – for
example, for games, graphs or animations.

textual area on your site even if the user hasn't got that font installed.
9. Features : html 5 outline algorithm
THE OUTLINE ALGORITHM:
- Can be thought of as a table of contents for your website.

Section and heading content is used to define the outline
-Body is established as the outline root
- Items are added to the outline as sectioning content is found
- Initial heading content is used to name these sections
- Sectioning content contained within these sections is shown as being nested in the outline
sectioning elements:
<article>
<aside>
<section>
<nav>
<h1 to h6>
Will all generate a new section in the outline algorithm
10. Features : algorithm example
