Web page
A webpage or web page is a "page" of the World Wide Web, usually in HTML format (the file extensions are generally *.htm and *.html) and with hypertext links to enable navigation from one page or section to another. Webpages often use associated graphics files to provide illustration, and these too can be clickable links. A webpage is displayed using a web browser, and can be designed to make use of applets (subprograms than run inside the page) which often provide motion graphics, interaction, and sound.
Webpages can be larger than fits on the screen. Except in special cases a page wider than fits on the screen, requiring horizontal scrolling, is impractical and therefore avoided: see page widening. A page higher than fits on the screen is more common and not problematic; it requires vertical scrolling to see all of it.
A collection of webpages stored in a single folder or within related subfolders of a web server is known as a web site. A webpage generally includes a frontpage named index.htm or index.html.
A difficulty in designing and testing webpages is that they should be suitable for many browsers and browser settings and different screen resolutions.
Graphics
The graphics file format in webpages is usually JPEG for photographs and GIF and PNG for other images such as diagrams, drawings, graphs, etc. (but these formats are also suitable for photographs). GIF is used for animations. All these are raster graphics. There is also the SVG format: Scalable Vector Graphics. Currently a more common way to supply vector graphics is with a PDF file, viewed either using a plug-in of the browser or a separate viewer. This is useful e.g. for a map, often a combination of a vector graphics layer and text, and possibly a raster graphics layer. This gives better results when zooming in than a GIF or PNG image (JPEG would be even worse due to compression artifacts).
Alternatively, on zooming in the server supplies a new image. In that case one can not download the whole map, unless perhaps piece by piece. See e.g. the links in Map#External links.
Also, as an example, compare the GIF and PDF province maps in South Holland#External links.

Creating a webpage
To create a webpage, one needs an HTML editor (a general one or a special webpage editor, like Microsoft FrontPage, Macromedia Dreamweaver, Mozilla Composer and so on), and a FTP program to upload the page to the web server. One can use the web browser to upload the webpage file to the server, but is not recommended.
Wiki is a special way to create or modify and upload webpages without FTP-ing or upload file, only filling a text formulary in a webpage. This page is an example.
