该组件支持简繁切换，如下方代码所示：

[[include :backrooms-wiki-cn:component:level-class
|lang=cn/tr
|class=等级
]]

在 lang 处选择语言，cn 表示简体中文，tr 表示繁体中文，不填默认选择简体中文。

自定义等级

[[include :backrooms-wiki-cn:component:level-class
|lang=cn/tr
|class=等级名字
|color=#000000（带有井号的十六进制色号代码。）
|image=链接（至图片的链接。）
|one=在这
|two=随便
|three=放文字
]]

使用 CSS 进行自定义：

你可以使用 CSS 进行额外的自定义，将代码放入到 [[module css]] 中或者是放入到页面的版式内都可以。在这一组件中，不要把 [[module css]] 放在 [[include]] 里面，把它放在那个的下面或者是页面的顶部或底部。
将这些代码放入到你的页面/版式中以编辑所有的颜色，因为组件的 |color= 部分仅能控制背景：

[[module css]]
.sd-container {
/* 字体 */
--sd-font: Poppins, Noto Sans SC, Noto Serif SC;

/* 边框 */
--sd-border: var(--gray-monochrome); /* 大多数等级 */
--sd-border-secondary: 0, 0, 0; /* 不适用 */
--sd-border-deadzone: 20, 0, 0; /* 死区 */

/* 标志 */
--sd-symbol: var(--sd-border) !important; /* 大多数标志 */
--sd-symbol-secondary: 255, 255, 255; /* 4 级以上的是白色 */

/* 文本 */
--sd-bullets: var(--sd-border) !important; /* 点句符文本颜色 */
--sd-text: var(--swatch-text-secondary-color); /* 顶部框文本颜色 */

/* 等级颜色 */
--class-0: 247, 227, 117;
--class-1: 247, 227, 117;
--class-1: 255, 201, 14;
--class-2: 245, 156, 0;
--class-3: 249, 90, 0;
--class-4: 254, 23, 1;
--class-5: 175, 6, 6;
--class-unknown: 38, 38, 38;
--class-habitable: 26, 128, 111;
--class-deadzone: 44, 13, 12;
--class-pending: 182, 182, 182;
--class-n-a: 38, 38, 38;
--class-amended: 185, 135, 212;
--class-omega: 25, 46, 255;
}
[[/module]]

旧版颜色：

如果你不喜欢新版的样式，想要用回旧版的红色边框色，只需要在你的页面中与组件一同引入下方的代码：

[[module css]]
.sd-container {
--sd-border: 90, 29, 27;
--sd-image: 90, 29, 27;
--sd-symbol: 90, 29, 27;
}
[[/module]]

Level IF-401是IF层群的第401层。

描述

Level IF-401是一处存在性与物质性均未被证实的异常层级，其所有信息均来自流浪者的梦境记录。该层级不具备可验证的物理方式，无法被常规方式稳定进入，被认为只能通过梦境进入的层级。

海浪。

该层级的环境呈现为一片无限延伸的海岸带，由沙滩、浅水区、礁石群与低矮建筑构成。天空维持在一种浅蓝色光照下，无太阳，无云层，无昼夜交替，整个层级的光照极其均匀，流浪者普遍描述其光感接近黄昏，但亮度与色温不发生变化。

层级的地表主体为沙滩，但本层级的沙子并非石英砂，该物质外观为细小，半透明，的结晶颗粒，质地坚硬，在受压与摩擦时会发出类似关节的轻响。这类沙子不具备普通沙子的流动性，在潮水冲刷下只会轻微起伏，不会被完全冲走。该物质无法被带出层级，在离开Level IF-401后会迅速消散。

海岸线上分布着大量米白色礁石建筑，建筑群沿海岸线呈不规则分布，彼此之间不形成街道或聚落。建筑整体由光滑，具有釉面质感的礁石构成，故其有着极高的反射率和低的摩擦系数。建筑群的墙基与礁石直接沉入沙滩中，与地形无缝融合，无法区分建筑与自然地貌的边界。建筑表面无任何人工雕琢痕迹，所有礁石皆以近乎完美圆弧过渡，无棱角，裂缝，拼接痕迹，破损处为呈现自然形成的缺口。建筑无门窗区分，洞口直接与沙滩和潮水相连，内部空间空旷且整洁，不存在家具，装饰以及杂物。

Level IF-401内存在着一棵巨大老榕树。该树位于沙滩东南处位置，树冠巨大，枝条低垂，挂满白色与浅橘色的丝带状物体，被流浪者称为许愿绳。树木无明显生长或枯萎迹象，根系深埋于沙滩中，不与任何建筑相连，其树洞内部空间异常，内部观测结果与外部尺寸不符，被认为是层级内重要的异常之一。

潮水区域波动低，水位高度固定，浪幅极小，不会形成真正意义上的海浪，其水温高于正常海水，不存在腐蚀性，饮用后无明显生理效应。水中无任何海洋生物，漂浮物或杂质。

由于所有信息均来自主观感受，且无法在物理层面被重复验证，Level IF-401的真实结构、边界、范围与内部仍处于完全未探明状态。

在礁石上发现的文段

我曾以为，海会记得一切。

忘忧岛的黄昏从来都是橘色的，像被谁打翻了一罐温温的橘子酱，漫过整片沙滩。小时候我和阿柚总在退潮后跑向礁石，把脚丫埋进细沙里，听浪一层一层漫上来，再退下去。她说，海浪会带走不开心的事，却会把约定留在风里。那时我们什么都信，信榕树，信潮汐，信勾在一起的小指能拴住一整个夏天。

后来岛变了。沙滩被翻新，榕树被圈起，连风里的味道都变得陌生。我站在曾经奔跑的地方，脚下的沙砾硌得人生疼，再也没有那种轻轻的、像指尖相碰的声响。一切都被标上了价格，一切都成了给外人看的风景。我开始害怕，害怕我们的约定也会像潮水一样，说退就退。

阿柚寄来的信我一直夹在课本里。纸上画着两个勾着手指的小人，旁边是她歪歪扭扭的字：暑假回来，再在榕树下拉一次钩。我回了信，写了满满一页，却再也没有等到下一封。

再回来时，岛已经不是原来的样子。台风卷走了榕树，卷走了沙滩，卷走了所有能被称作“回忆”的东西。海水漫上来，把一切都盖得严严实实，咸涩、冰冷，像一句没说完的话。

我坐在礁石上，看着海面。浪还在拍，可再也拍不回那个黄昏。

我把橘子汽水放在潮线上，看着它被慢慢卷走。

原来有些约定，不会被海浪打碎。

只会被海浪，永远藏起来。
