## This is 2nd level heading

This is a test paragraph.

### This is 3rd level heading

This is a test paragraph.

#### This is 4th level heading

This is a test paragraph.

##### This is 5th level heading

This is a test paragraph.

###### This is 6th level heading

This is a test paragraph.

## 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.

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.

## 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.

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: Mlle, 1st, and then some mathematical notations: ex, sin2x, 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`

## 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.

## Tables

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:

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
