Basic block level elements

This is a normal paragraph (p element). To add some length to it, let us mention that this page was primarily written for testing the effect of user style sheets. You can use it for various other purposes as well, like just checking how your browser displays various HTML elements by default. It can also be useful when testing conversions from HTML format to other formats, since some elements can go wrong then.

This is another paragraph. I think it needs to be added that the set of elements tested is not exhaustive in any sense. I have selected those elements for which it can make sense to write user style sheet rules, in my opionion.

This is a div element. Authors may use such elements instead of paragraph markup for various reasons. (End of div.)

This is a block quotation containing a single paragraph. Well, not quite, since this is not really quoted text, but I hope you understand the point. After all, this page does not use HTML markup very normally anyway.

The following contains address information about the author, in an address element.

Mon nom en francais, [email protected]
3 Rue Jules Ferry, Neuilly Sur Seine, France 94000

Lists

This is a paragraph before an unnumbered list (ul). Note that the spacing between a paragraph and a list before or after that is hard to tune in a user style sheet. You can't guess which paragraphs are logically related to a list, e.g. as a "list header".

One.
Two.
Three. Well, probably this list item should be longer. Note that for short items lists look better if they are compactly presented, whereas for long items, it would be better to have more vertical spacing between items.
Four. This is the last item in this list. Let us terminate the list now without making any more fuss about it.

The following is a menu list:

One.

Two.

Three. Well, probably this list item should be longer so that it will probably wrap to the next line in rendering.

The following is a dir list:

One.

Two.

Three. Well, probably this list item should be longer so that it will probably wrap to the next line in rendering.

This is a paragraph before a definition list (dl). In principle, such a list should consist of terms and associated definitions. But many authors use dl elements for fancy "layout" things. Usually the effect is not too bad, if you design user style sheet rules for dl which are suitable for real definition lists.

term: a word or other expression taken into specific use in a well-defined meaning, which is often defined rather rigorously, even formally, and may differ quite a lot from an everyday meaning

Text-level markup, in alphabetical order

CSS (an abbreviation; abbr markup used)
radar (an acronym; acronym markup used)
bolded (b markup used - just bolding with unspecified semantics)
Origin of Species (a book title; cite markup used)
a[i] = b[i] + c[i); (computer code; code markup used)
here we have some ~~deleted~~ text (del markup used)
an octet is an entity consisting of eight bits (dfn markup used for the term being defined)
this is very simple (em markup used for emphasizing a word)
Homo sapiens (should appear in italics; i markup used)
here we have some inserted text (ins markup used)
type yes when prompted for an answer (kbd markup used for text indicating keyboard input)
Hello! (q markup used for quotation)
He said: She said Hello! (a quotation inside a quotation)
you may get the message Core dumped at times (samp markup used for sample output)
this is not that important (small markup used)
~~overstruck~~ (strike markup used; note: s is a nonstandard synonym for strike)
this is highlighted text (strong markup used)
In order to test how subscripts and superscripts (sub and sup markup) work inside running text, we need some dummy text around constructs like x₁ and H₂O (where subscripts occur). So here is some fill so that you will (hopefully) see whether and how badly the subscripts and superscripts mess up vertical spacing between lines. Now superscripts: M^lle, 1^st, and then some mathematical notations: e^x, sin² x, and some nested superscripts (exponents) too: e^x² and f(x)^{g(x)^a+b+c} (where 2 and a+b+c should appear as exponents of exponents).
text in monospace font (tt markup used)
underlined text (u markup used)
the command cat filename displays the file specified by the filename (var markup used to indicate a word as a variable).

Some of the elements tested above are typically displayed in a monospace font, often using the same presentation for all of them. This tests whether that is the case on your browser:

This is sample text inside code markup
This is sample text inside kbd markup
This is sample text inside samp markup
This is sample text inside tt markup

Links

This is a text paragraph that contains some inline links. Generally, inline links (as opposite to e.g. links lists) are problematic from the usability perspective, but they may have use as “incidental”, less relevant links. See the document Links Want To Be Links.

Forms

This is a form containing various fields (with some initial values (defaults) set, so that you can see how input text looks like without actually typing it):

Name
Email
Birthday
Age
Phone
Satisfaction
Twitter

Button:

Reset button:

Single-line text input field:

Multi-line text input field (textarea):

The following two radio buttons are inside a fieldset element with a legend:

Legend

Radio button 1

Radio button 2 (initially checked)

Check those that apply

Checkbox 1

Checkbox 2 (initially checked)

A select element with size="1" (dropdown box):

A select element with size="3" (listbox):

Submit button:

Tables

The following table has a caption. The first row is in a thead, the second row is the tfoot, and the rest is in a tbody. The first column contain table header cells (th elements) only; other cells are data cells (td elements):

Sample table: Areas of the Nordic countries, in sq km
Country	Total area	Land area
Country	Total area	Land area
Denmark	43,070	42,370
Finland	337,030	305,470
Iceland	103,000	100,250
Norway	324,220	307,860
Sweden	449,964	410,928

Character test

The following table has some sample characters with annotations. If the browser’s default font does not contain all of them, they may get displayed using backup fonts. This may cause stylistic differences, but it should not prevent the characters from being displayed at all.

Char.	Explanation	Notes
ê	e with circumflex	Latin 1 character, should be ok
—	em dash	Windows Latin 1 character, should be ok, too
Ā	A with macron (line above)	Latin Extended-A character, not present in all fonts
Ω	capital omega	A Greek letter
−	minus sign	Unicode minus
⌀	diameter sign	relatively rare in fonts
