HTML5 syntax is compatible with both HTML4 and XHTML1. Want to close |
|
empty elements with a slash? Go for it. Rather not? Then don't. Want to use |
|
lower case? Upper case? Take your pick. In other words, you really don't have |
|
to change the way you handle these things, so don't worry, ok? |
|
|
|
HTML5 doctype is much simpler: |
|
|
|
New way: |
|
<!doctype html> |
|
|
|
Old ways: |
|
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" |
|
|
|
"http://www.w3.org/TR/html4/strict.dtd"> |
|
|
|
or |
|
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" |
|
|
|
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> |
|
|
|
Meta charset tag is much simpler: |
|
|
|
New way: |
|
<meta charset="UTF-8"> |
|
|
|
Old way: |
|
<meta http-equiv="Content-Type" content="text/html; charset=UTF- |
|
|
|
8" /> |
|
|
|
Divs are now used for styling rather than structure; HTML5 includes several |
|
new structural elements that help define parts of the document. Let's take a |
|
look at the main new structural elements that you'll probably use right away. |
|
|
|
(Note that included in the head is an HTML5 shiv that allows us to style elements in IE, |
|
and a basic CSS style is also included so we can help browsers that aren't caught up yet to |
|
render the new block-level elements as block-level elements. For now, it's easiest just to |
|
automatically include them. Understanding why can come later.) |

Main Structural Elements You'll Use Most Often in HTML5 |
|
|
|
<header> |
|
|
|
<nav> |
|
|
|
<section> |
|
|
|
<article> |
|
|
|
<aside> |
|
|
|
<footer> |
|
|
|
Although these sound like “positions” in a document, and very often will be |
|
used in that way, they really are about grouping and not positioning. You might |
|
have 3 <sections> in a page, with each <section> having its own <header> and |
|
<footer> for instance. (Note that these elements – like classes – can be used |
|
more than once on a page). |
|
|
|
But to keep things simple, for this document's purpose, let's just think of a |
|
very basic document that contains a top header, a menu for navigation, a |
|
content section that contains a couple of articles, a sidebar, and a footer. |
|
|
|
In HTML4 or XHTML, you probably would have used divs, classes and ids to |
|
group each of those areas. You can and should still use divs, classes and ids for |
|
styling reasons, but they may no longer be as necessary as before for |
|
structural purposes. Some documents may be able to get by without them |
|
completely, while most will probably still need them for styling. But again, for |
|
the purposes of learning the quick facts to create a simple HTML5 document, |
|
let's keep this really basic. |
|
|
|
Here's a simple way to code a very basic document that contains a top header, |
|
a menu for navigation, a content section that contains a couple of articles, a |
|
sidebar, and a footer in HTML5. |

As you can see, the structure is fairly simple, and you can style these new |
|
structural elements in the CSS. However, because you may have some of these |
|
structural elements within different groupings on a page (such as several |
|
sections having different headers and footers), you may want to style each |
|
differently. In that case, you can still assign ids and classes just as you would |
|
in HTML4 or XHTML. |
|
|
|
The point of the structural elements is to designate structure after all; |
|
presentation is dealt with in the CSS in whatever manner works best for you, |
|
using ids and classes. |
|
|
|
So what are the actual definitions of these new structural elements? |
|
|
|
<header> represents a group of introductory or navigational aids. (Things |
|
you'd usually wrap in a H1, H2, Hx, etc) |
|
|
|
<nav> represents a section of the document intended for navigation. (Like a |
|
menu) |
|
|
|
<section> represents a generic document or application section. It can be |
|
used together with the h1, h2, h3, h4, h5, and h6 elements to indicate the |
|
document structure. (Just a logical grouping such as a content section) |
|
|
|
<article> represents an independent piece of content of a document, such as |
|
a blog entry or newspaper article. (Independent is the key word here. If the |
|
piece of content could make sense plucked out of this document and placed |
|
somewhere else, it's probably an article) |
|
|
|
<aside> represents a piece of content that is only slightly related to the rest |
|
of the page. (Usually a sidebar, but could be another type of content that |
|
isn't directly related to the main content) |
|
|
|
<footer> represents a footer for a section and can contain information about |
|
the author, copyright information, et cetera. (You know, like... a footer) |
|
|
|
Of course, HTML5 comes with other interesting elements such as the video and |
|
audio elements, plus new and changed elements and attributes, but all of |
|
those belong in a separate cheat sheet. This one is to get you up and running |
|
fast, so there you have it. Just the basics that will let you quickly move from |
|
HTML4 or XHTML to HTML5 right now! |
