Above text was formatted as:

 The [[MediaWiki]] markup language supports many HTML tags, including <code><span style="font-family:Garamond;"></code> and such. Some of the fonts are:   

:* Garamond: <span style="font-family:Garamond;">This is [[Garamond|Garamond font]].</span>   

 :* Georgia:     <span style="font-family:Georgia;">This is [[Georgia font]].</span>   

 :* Courier:     <span style="font-family:Courier;">This is [[Courier (typeface)|Courier font]].</span>   

 :* Helvetica:   <span style="font-family:Helvetica;">This is [[Helvetica|Helvetica font]].</span>

Here are the tags to use if you wish to change the font in the text of an article. Please note, fonts that have the same cap height, do not always match in x-height, making them hard to mix inline without scaling. Based on Arial as the base font, Comic Sans MS, Georgia, Trebuchet MS and Verdana are safe to use inline. Times New Roman is not safe to use inline without scaling. Although Courier New has a lower height, it remains legible, and is the de facto monospace font. (Arial Black and Impact are not listed, as these are header fonts.)

• Here are examples of code to use, for various fonts.
• Safe to use inline (see above for details):

** <span style="font-family: Arial;">Arial</span>; the base font,  
** <span style="font-family: 'Comic Sans MS';">Comic Sans MS</span>,  
** <span style="font-family: Georgia;">Georgia</span>,  
** <span style="font-family: 'Trebuchet MS';">Trebuchet MS</span>  
** *<span style="font-family: Verdana;">Verdana</span>  
*Not safe to use inline (see above for details):
** <span style="font-family: 'Times New Roman';">Times New Roman</span>  
** <span style="font-family: 'Courier New';">Courier New</span>  
 
 

• below is how the font codes above would look when actually used.
• Safe to use inline (see above for details):
  • Arial; the base font,
  • Comic Sans MS,
  • Georgia,
  • Trebuchet MS
  • Verdana are safe to use inline.
• Not safe to use inline (see above for details):
  • Times New Roman
  • Courier New

Overriding font colour

To make a word have colour, use: <span style="color:hex triplet or colour name">text</span>

Note that you can't use the British spelling, "colour", in this context.

Examples:

• <span style="color:red">red writing</span> shows as red writing
• <span style="color:#0f0">green writing</span> shows as green writing
• <span style="color:#0000FF">blue writing</span> shows as blue writing

Template font colour

Template:Font color, or its redirect Template:Font colour, can also be used.

{{Font colour|fontcolour|backgroundcolour|Your text here}}

Example	Result
{{font color|red|This text is different}}	This text is different to change text-color only (Note: do not style text as a link)
{{font color|red|yellow|This text is different}}	This text is different to change text and background color
{{font color||yellow|This text is different}}	This text is different to change background color only note the two pipe-characters ||

This feature helps to get rid off the time for note-taking, and allow the user to select and re-order the pages according to the user's need.

Help:Books/Printed books , PediaPress
After completion of a book, Wikipedia allows to order printed books.

Help:Download as PDF
There is a button for ‘Download as PDF’ on left sidebar
While normally browsing Wikipedia, it allows download a page in PDF format. Wikipedia renders the page suitable for PDF, and sends to user.

Help:Printable , Printer-friendly
There is a button for ‘Printable version’ on left sidebar
Wikipedia also provide a printer-friendly version to read the page, within browser. This feature hides various options, links, hyperlinks, non-main informations such as references etc. Thus make easier read, print, copy, and saves paper also.

Help:Watchlist
Watchlist helps to bookmark an article for an user. Articles could be bookmarked by clicking the star-sign at top-portion of the page. User-account required to use and save bookmarks. However watchlist is saving only 30-days record !

Wikipedia:Hovercards,
https://www.mediawiki.org/wiki/Extension:Popups ,
Help:Preferences.

This is my very favourite feature in Wikipedia. While hovering on a link, it displays some of the contents , with a picture, from that link. It is quite more than tooltip/popups. It keeps a balance between flow and correlation.
However a user-account needed to save this Wiki-preference. Hovercard is available in Wikipedia preference.

Preference → Beta features → Hovercards.

Hyperlink ,
Wikipedia:Manual of Style/Layout
Wikipedia provides various Hyperlink s i.e. Wikilinks . Some inside article, some in before or after the article (such as Hatnote s like disambiguation page ( Wikipedia:Disambiguation ), not to confuse with ( Wikipedia:Hatnote#"Distinguish" ) , See also ( Wikipedia:Guide to layout#"See also" ) ,etc.). They help to understand the meanings of all the terms, find-out (often discover) related concepts, and distinguish similar concepts.

There is also a 'related-page' tool on preferences.
