This page is a translated version of the page Skin:Lakeus and the translation is 3% complete.

Lakeus is a skin that aims to provide a simple but all-functional experience. It's named after a character in the novel of one of the authors, Lakejason0.

Installation

Download and place the file(s) in a directory called Lakeus in your skins/ folder.
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadSkin( 'Lakeus' );
```
Done - Navigate to Special:Version on your wiki to verify that the skin is successfully installed.

Features

Simple but all-functional (at least most of them should work).
جاوا اسکرپٹ کے غیر فعال ہونے پر کام کرتا ہے۔
Customization through CSS variables.
Responsive design. Should work with desktop and tablet.
Sticky TOC. May be unstable.
A Theme designer. By enabling it in your preferences you can change and preview the theme in real time. For the most of time, only a few tweaks on basic variables are needed and it will produce an automagically calculated theme for you.
- It might be a bit buggy and unstable, so be sure to report any of the problems to me! You can always disable automatic calculation if you are not satisfied.

Notes

جب جاوا اسکرپٹ موجود نہ ہو تب بھی جلد کو قابل استعمال ہونا چاہیے۔ Several handy features may not be available though.
The skin made a dedicated menu for site that uses a language with LanguageConverter variants (e.g. Chinese (zh) and Serbian). When no variants available, the menu should be invisible.
RTL support hasn't been tested well, but main features are confirmed RTL compatible (e.g. sidebar menus).

Customization

CSS variables

Your CSS may not work in several special pages (like ترجیحات); it's an intended behavior of MediaWiki core due to security concerns, but site admins could set $wgAllowSiteCSSOnRestrictedPages to true to bypass it after understanding the risks.

Lakeus supports customization through CSS variables. ذیل میں تھیم تیار کرنے کے کئی طریقے ہیں، اور نتیجہ (سی ایس ایس کوڈ ہونا چاہیے) کو لاگو کرنے کے لیے آپ کو اسے Lakeus.css میں کاپی کرنا ہوگا، جو کہ تمام ویکی صارفین کے لیے MediaWiki:Lakeus.css اور اپنے لیے Special:MyPage/Lakeus.css پر پایا جا سکتا ہے۔

Theme Designer

Using the theme designer would be easier for anyone (at least I hope so). You'll only need to change the basic variables and the rest will be automatically calculated. You can disable the auto calculation for each variable that you don't really like the auto calculated result of it, and manually tweak it as you like.

To enable it, go to the preferences, select "Appearance", and you can find the option when the skin Lakeus is selected. Once enabled, it would load on every page.

Basically all the buttons and form inputs do what it literally means; just try them out if you are a bit confused. There are some variables that do not appear on every page, and they would be listed below:

Interface message box. These elements appears in situations like that a user group setting is successfully applied when JavaScript disabled, translation page edit notice warning, MediaWiki exceptions that appears on page editing, user talk page notices with no Echo and other notification extensions installed, and so on.

Preset themes

There will be some preset theme that is already here for you to use. You can share your own theme on the talk page as well. Come back later if there isn't any.

Vintage

A vintage theme, last exported on 1.1.7.

  --font-family: 'Roboto', -apple-system, blinkmacsystemfont, 'Segoe UI', 'Oxygen', 'Ubuntu', 'Cantarell', 'Helvetica Neue', sans-serif;
  --font-family-serif: 'Linux Libertine', 'Times New Roman', 'Liberation Serif', 'Nimbus Roman', 'Noto Serif', 'Times', serif;

  --header-elevation: var(--elevation);
  --mask-background: rgba( 0, 0, 0, 0.8 );
}

For example, to change the header's color to a light blue (e.g. #4FC3F7), it would be:

:root {
  --color-header: #4FC3F7;
}

Parameters

Parameter	Type	Default	Description
`$wgLakeusShowRepositoryLink`	Boolean	`true`	Determines whether to show the link to the skin's repository in the footer.
`$wgLogos`			For now, only `icon` and `wordmark` are recognized; keys like `svg`, `1x`, `1.5x` or `2x` are not used by the skin. Notice that other skins may utilize the image provided by `icon` AND other keys as well, so do not rely on the key to provide a icon only for this skin.
`$wgLakeusSiteNoticeHasBorder`	Boolean	`false`	Determines whether to add a skin provided border to site notice. Enabling it can be useful for plain text notices, but if you've already got a border in your site notice content, you can leave it disabled.
`$wgLakeusShouldAnimatePortlets`	Boolean	`false`	Determines whether to enable portlets animations (e.g. fade in and out effects when opening or closing portlets). May cause visual artifacts when enabled due to z-index issues.
`$wgLakeusShowStickyTOC`	Boolean	`false`	Determines whether to show sticky TOC.
`$wgLakeusCustomIndicators`	Array	`[]`	Experimental. Adds custom skin-wide indicators. This is PROBABLY NOT how you should add page status indicators and therefore experimental. This array consists of data of indicators, and each entry should consist of 3 properties: `id`, `class`, `html`. It is suggested to follow the format of proper indicators added in wikitext, which means: `id` should be a string prefixed with `mw-indicator-` with a unique name of the indicator after the prefix. Indicators in wikitext take precedence, that is, indicators added by this variable are ignored when they have the same id with ones added by wikitext. `class` is always the string `mw-indicator`. `html` is a string consists of HTML fragment of the indicator. A `<div>` tag with the class `mw-parser-output` is always present as the container tag, since normally contents of indicators are parsed wikitext. The container tag is not present in indicators added by MediaWiki core, like help links indicators on special pages. Write the content as you like.

Sidebar icons

Unfortunately, it's not easy to add icons to the skin without including many images on page. If you can bear the loading time of web font icons, you can try this out as follows. To start with, include the icon font face (in this whole example, Material Icons) in your CSS (Lakeus.css). You may have loaded some font faces in other places other than Lakeus.css, in which case just ensure that they don't conflict with each other.

/* MD Icons */
/* fallback */
@font-face {
  font-family: 'Material Icons';
  font-style: normal;
  font-weight: 400;
  src: url(https://fonts.gstatic.com/s/materialicons/v70/flUhRq6tzZclQEJ-Vdg-IuiaDsNc.woff2) format('woff2');
}

Then, as we are going to use pseudo elements, some paddings and extra settings to create space for icons are applied:

.toggle-list__list a {
    padding-left: calc(8px + 25px);
}

.toggle-list__list a::before {
    content: '';
    width: 0;
    height: 0;
    display: inline-block;
    font-family: 'Material Icons';
    font-size: 18px;
    transform: translateX(-25px) translateY(3px);
    /* Display Optimizing */
    -webkit-font-smoothing: antialiased;
    text-rendering: optimizeLegibility;
    -moz-osx-font-smoothing: grayscale;
    font-feature-settings: 'liga';
}

Now, it's time to add the actual icons. You can use Devtools (The tool opened by right click and then Inspect Element) to see the list items' IDs, and we are finally going to set the actual content of the pseudo elements (icons):

/* Navigation */
#n-mainpage-description a::before {
    content: 'home';
}

#n-recentchanges a::before {
    content: 'auto_awesome';
}

#n-randompage a::before {
    content: 'shuffle';
}

#n-portal a::before {
    content: 'forum';
}

#n-help-mediawiki a::before {
    content: 'help_center';
}

In this example, Material Icons supports certain strings (used here) and code points for an certain icon. For what strings or code points could be used for Material Icons, see Icons - Google Fonts. Feel free to add more rules for your own site, for example one of the authors' site got an admin noticeboard:

#n-adminnoticeboard a::before {
    content: 'groups';
}

The #n-... part corresponds with the system message you used in your MediaWiki:Sidebar.

Personal menu icons

Personal menu works likewise.

Extended content

/* Personal Menu */
#p-personal a {
    padding-left: calc(0.75em + 25px);
}

#p-personal a::before {
    content: '';
    width: 0;
    height: 0;
    display: inline-block;
    font-family: 'Material Icons';
    font-size: 18px;
    transform: translateX(-25px) translateY(3px);
    -webkit-font-smoothing: antialiased;
    text-rendering: optimizeLegibility;
    -moz-osx-font-smoothing: grayscale;
    font-feature-settings: 'liga';
}

#pt-userpage a::before {
    content: 'person';
}

#pt-mytalk a::before {
    content: 'chat_bubble';
}

#pt-adminlinks a::before {
    content: 'admin_panel_settings';
}

#pt-preferences a::before {
    content: 'settings';
}

#pt-betafeatures a::before {
    content: 'science';
}

#pt-watchlist a::before {
    content: 'star';
}

#pt-mycontris a::before {
    content: 'emoji_events';
}

#pt-logout a::before {
    content: 'logout';
}

#pt-login a::before {
    content: 'login';
}

#pt-createaccount a::before {
    content: 'person_add';
}
