Editing Help:User style (section)

=== Samples ===
Custom styles can be placed in each user's personal CSS files, such as [[Special:MyPage/common.css]], which each user can edit to set personal styles.
<syntaxhighlight lang="css">
/* make the background behind the content area and the tabs a light grey */

==== Rounded corners ====
[[Image:Rounded corners.jpg|thumb|100px|Rounded corner rules in Firefox]]
<syntaxhighlight lang="css">
/* make a few corners round */
#p-cactions ul li, #p-cactions ul li a {
  border-top-left-radius: 1em;
  border-top-right-radius: 1em;
}
#content {
  border-top-left-radius: 1em;
  border-bottom-left-radius: 1em;
}
.pBody {
  border-top-right-radius: 1em;
  border-bottom-right-radius: 1em;
}
</syntaxhighlight>

==== Print view tweaks ====
<syntaxhighlight lang="css">
/*
** Place all print-specific rules in an @media print block.
*/

/* save ink and paper with very small fonts */
@media print {
    #footer,
    #content,
    body { font-size: 8pt !important; }
    h1 { font-size: 17pt }
    h2 { font-size: 14pt }
    h3 { font-size: 11pt }
    h4 { font-size: 9pt }
    h5 { font-size: 8pt }
    h6 {
        font-size: 8pt;
        font-weight: normal;
    }
}

/* Advanced things: using :before and :after it's possible to add formatting
this here adds the full href of a link after it (not needed in the current version): */
@media print {
  #content a:link:after,
  #content a:visited:after {
     content: " ( " attr(href) " ) ";
  }
}
</syntaxhighlight>

==== Make the user toolbar a sidebox ====
Tested to work in Camino, Safari and Internet Explorer 7.
<syntaxhighlight lang="css">
/* Transform the user toolbar into a sidebox */
#p-personal {
    position:relative;
    z-index:3;
    width: 11.6em;
}

#p-personal .pBody {
    width: 10.7em;
    border: none;
    margin: 0 0 0.1em 0em;
    float: none;
    overflow: hidden;
    font-size: 95%;
    background: White;
    border-collapse: collapse;
    border: 1px solid #aaaaaa;
    padding: 0 0.8em 0.3em .5em;
}

#p-personal ul {
    line-height: 1.5em;
    list-style-type: square;
    list-style-image: url("/style/monobook/bullet.gif");

    font-size:95%;
    margin: 0 0 0 1.5em;
    padding:0;
    text-align:left;
    text-transform: none;
}

#p-personal li {
    display: list-item;
    padding:0;
    margin: 0 0 0 0;
    margin-bottom: 0.1em;
}

/* suppress the person icon by your username */
/* needed if not already in place */
li#pt-userpage { background: none }
</syntaxhighlight>
See the monobook [http://test.wikipedia.org/style/monobook/main.css main.css] for the full styles in use by default.

==== Fix the top bar's position while you scroll ====
This style allows Vector Legacy users to keep the top bar (with the search bar and the talkpage, edit, userpage, etc. links) visible as you scroll, similar to Vector 2022:

<syntaxhighlight lang="css">
@media screen {
    #mw-head {
        position: fixed;
        background: linear-gradient(to bottom,#fff 50%,#f6f6f6 100%);
    }
}
</syntaxhighlight>

==== Fix the sidebar's position while you scroll ====
In the Vector Legacy skin, the sidebar's position can be fixed easily:

<syntaxhighlight lang="css">
/* Fix sidebar */
div#mw-panel { position: fixed;
  overflow: auto;
  top: 0px;
  bottom: 0px;
  height: 100%;
  /* Prevent content overlay when sidewards scrolling */
  background-color: #F6F6F6;
  border-right: 1px solid #A7D7F9;
}
/* Prevent sidewards scrolling in pre elements */
pre {
  overflow: auto;
  max-height: 25em;
}
</syntaxhighlight>

[[Image:Fixed sidebar.png|thumb|This script and CSS makes the sidebar stay in the same position on the screen as you scroll]]

This may have undesirable side effects in Chrome; e.g., when viewing a page like the very common.css page you just edited to put this code in, the viewable content will become much shorter, and require vertical scrolling in a frame.

The ''Cologne Blue'' skin has an option for a "floating left" quickbar, which causes the navigation links and toolboxes and such to stay in the same position on the screen while you scroll. This provides the same functionality for the ''Monobook'' skin (in Mozilla). See [[meta:Help:User style/floating quickbar]].

==== Monobook menus with serif fonts in the content area ====
A quick-and-dirty combinaton of Monobook menus with serif fonts in the text area is found at [[User:Tillwe/monobook.css]] (in the first part). Also displays table-formatted things more or less correctly. There are some quirks and bugs (some because the CSS scheme of Wikipedia doesn't seem to be too thoughtful). Works on Netscape7/Win98 for the author.

==== Moving category links ====

<syntaxhighlight lang="css">
/******************************************************************/
/* moving catlinks to the right                                   */
/******************************************************************/

/* move the catlinks box */
#catlinks {
  position:absolute;
  z-index:1;
  border: 1px solid #aaaaaa;
  background: #fafaff;
  right:1em;
  top:-0.25em;
  width:10.5em;
  float:right;
  margin: 0.2em;
  padding:0.2em;
}

/* format the catlinks itself */
p.catlinks {
  color: #aaaaaa;
  font-family: Verdana,sans-serif;
  font-size:67%;
  line-height: 1.5em;
  text-align:left;
  text-indent:0;
  text-transform: none;
  white-space:normal;
  margin: 0.2em;
}

#p-personal h5 {
    display: inline;
}

/* format links in the catlinks (as distinguished from ":" and "|") */
p.catlinks a {
  color:#888888;
}
</syntaxhighlight>

==== Diff view styling ====
<syntaxhighlight lang="css">
/* don't use a smaller font */
td.diff-addedline, td.diff-deletedline, td.diff-context { font-size: 100% };

/* underline just the text that's different */
span.diffchange { text-decoration:underline; }
</syntaxhighlight>

==== Removing the "(thank)" buttons in History log ====
<syntaxhighlight lang="css">
/*Suppress "(thank)" buttons*/
.mw-thanks-thank-link { display:none; }
</syntaxhighlight>

==== Hiding long instruction messages ====
<syntaxhighlight lang="css">
/* hide View-Source blurb when editing a protected page */
#mw-protectedpagetext { display: none; }
</syntaxhighlight>

As with other CSS styles above, edit [[Special:MyPage/skin.css]] or [[Special:MyPage/common.css]] to insert the customized CSS, and then refresh the browser's cache.

==== Add style formatting to discussion threads ====

There is an experimental style sheet to add vertical lines to the left of discussion threads and to alternate between two different background colours. See [[User:Isaacl/style/discussion-threads]] for more details and a mockup of the appearance.
