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 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.

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:

The following is a dir list:

This is a paragraph before a numbered list (ol). Note that

3. Three. Well, probably this list item should be longer. Note that if

4. Four. This is the last item in this list.
   Let us terminate the list now without making any more fuss about it.

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

• CSS (an abbreviation;
  abbr markup used)

• radar (an acronym; acronym markup used)
• bolded (b markup used – just bolding with unspecified
  semantics)

• big thing (big markup used)
• large size (font size=6 markup used)
• Courier font (font face=Courier markup used)
• red text (font color=red markup used)
• 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

• main page
• Unicode Standard, chapter 6

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

Tables

The following table has a caption. The first row and the first column
contain table header cells (th elements) only; other cells
are data cells (td elements), with align="right"
attributes:

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.

Hyphenation

In the following, a width setting should cause some hyphenation,
depending on support to various methods of hyphenation.

CSS-based hyphenation

Until recently the great majority of naturalists believed that species were immutable productions, and had been separately created. This view has been ably maintained by many authors.

JavaScript-driven hyphenation

Until recently the great majority of naturalists believed that species were immutable productions, and had been separately created. This view has been ably maintained by many authors.

Explicit hyphenation hints (soft hyphens)

Un­til re­cent­ly the great
ma­jor­i­ty of nat­u­ral­ists

im­mu­ta­ble
pro­duc­tions,
and had been sep­a­rate­ly cre­at­ed.
