Salamanders are a group of amphibians with a lizard-like appearance, including short legs and a tail in both larval and adult forms.
Several species of salamander inhabit the temperate rainforest of the Pacific Northwest, including the Ensatina, the Northwestern Salamander and the Rough-skinned Newt. Most salamanders are nocturnal, and hunt for insects, worms and other small creatures.

In all the treetops
Hearest thou
Hardly a breath;
The birds are asleep in the trees:
Wait, soon like these
Thou too shalt rest.

This is a normal paragraph. It contains some text. According to some sources, paragraphs should be 30em x the font size (for example, 10px font size = 300px wide paragraph). Use ems to make this happen. Also, line height should be 6 - 7px bigger than the font size. It may or may not be appropriate to use ems for this. Here is some small text
Complex computer systems find their way into everyday life, and at the same time the market is saturated with competing brands. This has made usability more popular and widely recognized in recent years, as companies see the benefits of researching and developing their products with user-oriented methods instead of technology-oriented methods. By understanding and researching the interaction between product and user, the usability expert can also provide insight that is unattainable by traditional company-oriented market research. For example, after observing and interviewing users, the usability expert may identify needed functionality or design flaws that were not anticipated. A method called contextual inquiry does this in the naturally occurring context of the users own environment.
There is no consensus about the relation of the terms ergonomics (or human factors) and usability. Some think of usability as the software specialization of the larger topic of ergonomics. Others view these topics as tangential, with ergonomics focusing on physiological matters (e.g., turning a door handle) and usability focusing on psychological matters (e.g., recognizing that a door can be opened by turning its handle).

Okay, so here's something kind of sort of new. The figure tags are very useful when displaying images with figures and captions and what-not. This paragraph needs to be a little longer, so here comes some lorum ipsum!

The <q> tag is used to define a short quotation: do not use me

Here are some blockquotes with cite tags

This paragraph contains a link, some em text (typically italicized), and some strong test, typically bolded. In addition don't forget to style the <abbr> tag: CSS tag! The <sup> tag: 1st. The <sub> tag: McLaughlin.
A new tag is the <progress> tag, which shows progress: . Here's another example: . You can style them based on their value and max attributes.
The following content is inside an address tag (most browsers typically render this in italics):

It is usually a good idea to use the <code> tag for inline code, like:
this is some code. There is also the <sampe> tag, which defines sample output (not the same as code), so you should style it
similarly, but perhaps a tiny bit different: this is some sample output. Also, there is the <kbd> tag for marking up keyboard
input (ie. keystrokes). Here are some keystrokes: Ctrl + Alt + \ +
Q
Final there's the <var> tag. It's kind of ambiguous, but from best I can tell, it is used to apply custom markup to a variable inside of a
<code> block. Example: variable = 1234.56. It is probably a good idea to style it in normal paragraph context, too:
a_variable.
The above examples describe inline code. There is also block code, which can be styled effectively with CSS. Use the <pre> tag to style that code. Here is some basic <pre> tag stuff:
I am the very model of a modern Major-General,
I've information vegetable, animal, and mineral,
I know the kings of England, and I quote the fights historical
From Marathon to Waterloo, in order categorical;
I'm very well acquainted, too, with matters mathematical,
I understand equations, both the simple and quadratical,
About binomial theorem I'm teeming with a lot o' news,
With many cheerful facts about the square of the hypotenuse.
I'm very good at integral and differential calculus;
I know the scientific names of beings animalculous:
In short, in matters vegetable, animal, and mineral,
I am the very model of a modern Major-General.
I know our mythic history, King Arthur's and Sir Caradoc's;
I answer hard acrostics, I've a pretty taste for paradox,
I quote in elegiacs all the crimes of Heliogabalus,
In conics I can floor peculiarities parabolous;
I can tell undoubted Raphaels from Gerard Dows and Zoffanies,
I know the croaking chorus from The Frogs of Aristophanes!
Then I can hum a fugue of which I've heard the music's din afore,
And whistle all the airs from that infernal nonsense Pinafore.
You may want to use the <pre><code> combination to style preformatted code separately from regular preformatted text:
//a terrible idea -- breaking the right-click functionality on web sites
var message="Copyright Year by Your Site. WARNING ! All content contained within this site is protected by copyright laws. Unauthorized use of our material is strictly prohibited.";
function click(e) {
if (document.all) {
if (event.button==2||event.button==3) {
alert(message);
return false;
}
}
if (document.layers) {
if (e.which == 3) {
alert(message);
return false;
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
The <del> and <ins> tags are especially useful in preformatted blocks. Typically, you want to use a red background for <del> tags, and use a green background for <ins> tags. Below are some preformatted blocks in a table with two columns, with these tags in use.

The <cite> tag is used to provide citations within HTML, similar to how you would provide footnotes in printed text. Here is a citation, in context (mouse over it): As outlined in The Battle Cry of Freedom , the Civil War had many complex causes.
The <summary> tag is a block-level item, that can be used to provide a summary for an article or section of your site:
