Editing Help:Preferences (section)

== Appearance ==
:{{myprefs|Appearance|Details|[[mw:Help:Preferences#Appearance]]}}
Change the web browser experience.

=== Skin ===
=== Skin Preferences ===
* Choose the "skin", or "theme" of how Wikipedia is displayed.
* Access your <span style="color:#CC2200">Custom CSS</span> or <span style="color:#CC2200">Custom JavaScript</span> for individual skins and for global settings that apply to all skins. If the links are blue, you have created these special pages and this is a quick way to access and edit them. If the links are red, clicking the link will create the special page. You can also access your cross-wiki CSS and JavaScript pages from this section, but the color of the links will always be that of external links.

=== Reading Preferences ===

=== Date format ===
{{See|mw:Help:Preferences#Date format/Time offset}}
* Option to set your date and time preferences; this is how dates will appear in article History pages, logs, etc. If set to "No preference", the format is HH:MM, DD MMMM YYYY ([[UTC]]), for example: {{CURRENTTIME}}, {{CURRENTDAY}}&nbsp;{{CURRENTMONTHNAME}} {{CURRENTYEAR}} (UTC).

=== Time offset ===
* Shows the server time (UTC) and the local time based on the optional Time zone setting. You may opt to use the server time (UTC), have the offset calculated by the clock in your computer, or specify an offset from UTC in hours or by location.
* This does not affect times saved in editable pages, such as timestamps in signatures. For that, see [[Wikipedia:Comments in Local Time]].

=== Files ===
* The images in an article are just a '''thumbnail''' (a preview). These will always be one of eight possible ''[[Help:Files#Using files|Thumbnail]] sizes''. For the larger screen sizes choose the maximum, and for the smaller screen sizes choose the minimum thumbnail size. The default 220px is a midrange thumbnail-size. Have you changed your font size? Then you should match that font size to your chosen thumbnail size to increase caption readability.

* While viewing an article, if you click a thumbnail you will activate '''''Media Viewer'''''. ''Media Viewer'' is JavaScript, and it uses processing resources. It loads all the images in the article at high resolution, and this uses networking resources. This is the default. You can turn off ''Media Viewer'' to save resources: 1) to control all image sizing, 2) to navigate directly to a file page (instead) when you click on a thumbnail.

* You can target the '''''Image size limit''''' of the ''file page'' main image, (displayed in the front matter). On a faster network choose a larger size, and on a slower network choose a smaller ''Image size limit''. The default  800&times;600px is a midrange ''Image size limit''. ''File pages'' are on Commons wiki, and if logged in there, going there overrides your settings here.

* Note that you can both turn off ''Media Viewer'' and set a small ''Image size limit'', and yet you will not limit your ability to avail yourself of any high resolution images listed at the bottom of that file page, when wanted. Doing so you can get full manual control of any unwanted, automatic bogging-down of your surfing speed caused by automated choices concerning [[wp:ns|'''File''' namespace]] interactions initiated by clicking on an image.

=== Diffs ===
* Option to not show page content below the diffs; checking this will suppress the page preview of the difference you're viewing.
* Option to omit a diff after performing a rollback <!-- I'm not sure how to describe this; please help if you can! -->

=== Advanced options ===
* Choose to display hyperlinks with underlines in your browser window always, never, or by browser or Wikipedia-skin default.
* Format links as stub links when the article they link to is smaller than the threshold you set on file size. Stub link formatting changes the link color to the dark brown displayed in this option's text. This option can help you see links to small articles (more likely to be stubs) so that you might expand them. It is also useful for spotting links to [[Help:Disambiguation pages|disambiguation pages]], which are also relatively small. They are usually linked to in error, but often contain on their list a link to the correct article, making this error easy to fix.
* Show hidden categories.

=== Math ===
* Choose [[Help:math|TeX, or MathJax]] for displaying mathematical formulas.

=== Languages ===

* Choose to display a more compacted language list.
