Background images

If you want to change the background image of your wiki using CSS, look no further. Generally, you can accomplish this using

body {
    background-image: url(<replace this with the url of the image you want the background to be>);
    background-color: <changes the color of the background, use a hex code or color name (i.e. "red")>;
    background-blend-mode: <combines two or more background layers together with different blend modes, use one of the names of the blend mode to change the resulting background appearance (examples: "color-dodge", "screen", "multiply", "hard-light", "difference", "luminosity")>
    background-attachment: <set to scroll to allow it to scroll with the page, or to fixed to keep its position static>;
    background-position: <set to either the directions from which to start the image (i.e. "top left", "left center", "right center", etc), percentages (x% y%), or position (xpos ypos). (Note: % and pos are mixable)>
    background-repeat: <the default setting is repeating the image both vertically and horizontally, setting to repeat-y will repeat the image only vertically, setting it to repeat-x will repeat it only horizontally, and setting it to no-repeat prevents it from repeating at all.>;

Some fine tuning may be required, but those are the basics.

    color: white;
  • .page
    • Page specific class
    • This page's is .page-CSS_Cookbook

    font-weight: bold;

Site enhancements

Blackout customization


To customize the black out that appears when viewing an image on a lightbox, use this CSS snippet below:

.blackout {
    background: #84dcff;
    mix-blend-mode: overlay;

Change the color of the background #84dcff to the intended color and the blending type overlay to the intended mixing mode.

Blurry background


This CSS snippet by Dorumin adds blur to the background.

Note: The browser support is relatively poor in the IE-Edge side, but you probably shouldn't expect everything to work if you're using IE anyways. It will just show a non-blurry image.

body::before {
    content: '';
    background-image: url(image-url);
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background-repeat: no-repeat;
    background-size: cover;
    background-position: 50%;
    -webkit-filter: blur(5px);
    filter: blur(5px);

The blur effect should usually be limited to 2-5px. In case body already has a background defined, you can always remove it with:

body {
    background-image: none !important;

Cursor customization


If you want to change the icon displayed as your cursor, you can use:

/* This cursor icon will be displayed normally */
body {
    cursor: url("<insert URL to cursor icon>");
/* This cursor icon will be displayed when hovering or clicking on links */
a:hover, a:active {
    cursor: url("<insert URL to cursor icon>");

Fix the toolbar width in the VisualEditor


This CSS snippet by JustLeafy fixes the width of the toolbar of VisualEditor, in order to make it as wide as the editing area.

.ve-init-mw-viewPageTarget-toolbar {
    border-top: none;
} {
    margin-left: -10px;
    margin-right: -10px;

"No article text" background


This site-wide only CSS snippet by Master Ceadeus 27 adds a background image to the missing article message:

#mw-content-text .noarticletext {
    background-image: url('<insert error image URL>');
    background-blend-mode: normal;
    background-size: cover;

Profile background


If you want to insert a background image to the right bottom corner of profiles of users, you can use:

.UserProfileMasthead .masthead-info {
    background-image: url("<insert URL to profile background image>");
    background-repeat: no-repeat;
    background-blend-mode: normal;
    background-position: right bottom;

Note: Add color: white; if the background image has a dark background.

Round div corners


This CSS snippet by PhilippL rounds the corners on <div>s.

#WikiaPage div,
#WikiaPage .avatar,
#WikiaPage section,
#WikiaPage table,
#WikiaPage .WikiaMenuElement,
#WikiaPage .widget-box,
#WikiaPage .preview_mobile.preview_icon,
#WikiaPage #wpPreviewMobile,
#WikiaPage #articleCategories {
    border-radius: 5px;

Scrollbar customization


If you want to customize your wiki's scrollbar, you can use these CSS selectors to apply various properties to it:

/* Makes the scrollbar 8px wide */
::-webkit-scrollbar {
    width: 8px;
/* Makes the scrollbar track have a black background */
::-webkit-scrollbar-track {
    background: black;
/* Makes the scrollbar bar have a green background */
::-webkit-scrollbar-thumb {
    background: #228B22;
/* Makes the background for the scrollbar bar a darker shade of green when hovered */
::-webkit-scrollbar-thumb:hover {
    background: #222;

Note: Scrollbar customization is only supported in certain browsers, like Chrome, Opera and Safari.

Source Editor header improvements


This CSS snippet by JustLeafy adds minor improvements into the header of the classic editor, including a different color, box shadow removal and some opacity.

/* Source Editor Header Improvements*/
.EditPageHeader {
    opacity: .95;
    background-color: darkgreen;
    border-bottom: none;
    box-shadow: none;
    color: #fff;
/* Fix wrong colored links */
.EditPageHeader > .wordmark,
.EditPageHeader > h2,
.EditPageHeader > h1 a,
.HelpLink > a,
.NotificationsLink > a {
    color: inherit;

Unhide Lightbox Add To Article Button


This CSS snippet by JustLeafy unhides the add to article option from the lightbox. The add to article option is simply used to add the image the user currently is viewing in the lightbox into an article by typing the article's name in the inputbox that will appear after clicking the "Add to Article" button.

.LightboxModal .lightbox-add-to-article {
    display: initial;

Unhide the amount of characters remaining in chat


This CSS plugin by JustLeafy keeps the characters remaining feature unhidden no matter how many characters were typed.

/** Unhide Characters Remaining **/
/* Display the "characters remaining" feature at any time */
body .remaining {
    display: initial;
    font-weight: bold;
    margin-right: 5px;
    margin-top: 30px;
    z-index: 1;
/* Limiting the width of the chat message inputbox to keep space for this feature */
.Write [name="message"] {
    width: 96%;

Username highlighting


This CSS snippet highlights links to an administrator's userpage, Message Wall, contributions and blog listing:

a[href$="/Admin's_Username"] {
    /* changes the color of the username */
    color: #006600 !important;
    /* makes the username bold */
    font-weight: bold !important;
    /* changes the font of the username */
    font-family: Arial !important;
    /* other CSS goes here */

Change "Admin's Username" to the username of the administrator you intend to highlight, #006600 to the intended color of highlighting and Arial to the intended font for the highlight. You can also remove certain sections if you don't need them in the highlight.
