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.

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)
  • 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: Mlle, 1st, and then some mathematical notations: ex, sin2 x, and some nested superscripts (exponents) too: ex2 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


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.


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):

The following two radio buttons are inside a fieldset element with a legend:
Check those that apply


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:

Sample table: Areas of the Nordic countries, in sq km
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


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 be­lieved that spe­cies were im­mu­ta­ble pro­duc­tions, and had been sep­a­rate­ly cre­at­ed. This view has been ably main­tain­ed by many au­thors.
