+
+# blivechat 自定义 CSS 参考
+
+blivechat 软件获取 bilibili 直播弹幕并以 HTML 形式在 OBS 中嵌入显示。默认样式模仿 YouTube，但可通过自定义 CSS 修改。
+
+## 输出
+
+输出为一个 CSS 文件。
+
+如果用户未指定输出路径，则询问保存位置。推荐 `data/custom_public/preset.css`，因为在 blivechat 设置中启用 *导入服务器预设 CSS* 即可自动导入该文件。
+
+**输出必须包含以下内容：**
+```css
+/* （必需）透明背景 */
+body,
+yt-live-chat-renderer,
+yt-live-chat-ticker-renderer,
+yt-live-chat-author-chip #author-name {
+  background-color: transparent;
+}
+
+/* （必需）隐藏滚动条 */
+body,
+yt-live-chat-item-list-renderer #item-scroller {
+  overflow: hidden;
+}
+```
+
+## 参考文件
+
+- DOM 结构源码：`frontend/src/components/ChatRenderer/index.vue`
+- 内置 YouTube 样式：`frontend/src/assets/css/youtube/`——默认样式未被覆盖时可以参考
+- [聊天气泡风格 CSS 示例](references/bubble.css)
+- [纯文字无消息背景 CSS 示例](references/text.css)——添加文字描边以提高对比度
+
+## 常用模式
+
+### 修复含有大表情的文本消息中头像和用户名没有垂直对齐的问题
+
+大表情会把文本消息的高度撑大，导致头像和用户名没有垂直对齐。
+
+修复方式1，指定顶端对齐：
+```css
+yt-live-chat-text-message-renderer #content:has(.emoji.blc-large-emoji) > * {
+  vertical-align: top;
+}
+```
+
+修复方式2，大表情换行显示：
+```css
+yt-live-chat-text-message-renderer #message:has(.emoji.blc-large-emoji) {
+  display: block;
+}
+```
+
+### 区分舰队等级
+
+文本消息 `yt-live-chat-text-message-renderer` 和上舰消息 `yt-live-chat-membership-item-renderer` 带有 `blc-guard-level` 属性区分舰队等级。
+
+**blc-guard-level 取值：**
+- `0`：非舰队成员
+- `1`：总督
+- `2`：提督
+- `3`：舰长
+
+### 区分付费消息金额档位
+
+付费消息 `yt-live-chat-paid-message-renderer` 带有 `blc-price-level` 属性区分金额档位。其值从低到高为 `0`-`7`，`0` 代表免费礼物。
+
+### 引用本地资源文件
+
+如需引用本地资源，将文件放入 `data/custom_public/` 目录，通过绝对 URL `/custom_public/` 引用。例如 `data/custom_public/img/bg.png` 可通过 `/custom_public/img/bg.png` 引用。
+
+禁止使用 `file:` 协议引用本地文件，这种方式不可移植到其他主机。

 用于OBS的仿YouTube风格的bilibili直播评论栏

-最近喜欢看VTuber，想为此写些程序，于是有了这个东西。~~写到一半发现有类似项目了：[bilibili-live-chat](https://github.com/Tsuk1ko/bilibili-live-chat)、[BiliChat](https://github.com/3Shain/BiliChat)~~
+![OBS截图](./screenshots/obs.png)

-![OBS截图](https://github.com/xfgryujk/blivechat/blob/master/screenshots/obs.png)  
-![Chrome截图](https://github.com/xfgryujk/blivechat/blob/master/screenshots/chrome.png)  
-![样式生成器截图](https://github.com/xfgryujk/blivechat/blob/master/screenshots/stylegen.png)  
+![Chrome截图](./screenshots/chrome.png)
+
+![样式生成器截图](./screenshots/stylegen.png)

 ## 特性
+
 * 兼容YouTube直播评论栏的样式
-* 金瓜子礼物模仿醒目留言显示
 * 高亮舰队、房管、主播的用户名
-* 支持屏蔽弹幕、合并相似弹幕等设置
-* 自带样式生成器
-* 支持自动翻译弹幕、醒目留言到日语
+* 自带两种样式生成器，经典YouTube风格和仿微信风格
+* 支持屏蔽弹幕、合并礼物等设置
+* 支持前端直连B站服务器或者通过后端转发
+* 支持自动翻译弹幕、醒目留言到日语，可以在后台配置翻译目标语言
+* 支持标注打赏用户名的读音，可选拼音或日文假名
+* 支持配置自定义表情，不需要开通B站官方表情
+* 支持[自定义HTML模板](https://github.com/xfgryujk/blivechat/wiki/%E8%87%AA%E5%AE%9A%E4%B9%89HTML%E6%A8%A1%E6%9D%BF)
+* 支持[插件开发](https://github.com/xfgryujk/blivechat/wiki/%E6%8F%92%E4%BB%B6%E7%B3%BB%E7%BB%9F)

 ## 使用方法
-### 本地使用
-1. 下载[发布版](https://github.com/xfgryujk/blivechat/releases)（仅提供x64 Windows版）
-2. 双击`blivechat.exe`运行服务器，或者用命令行可以指定host和端口号：
-   ```bat
-   blivechat.exe --host 127.0.0.1 --port 12450
-   ```
-3. 用浏览器打开[http://localhost:12450](http://localhost:12450)，输入房间ID，保存配置，复制房间URL
-4. 用样式生成器生成样式，复制CSS
-5. 在OBS中添加浏览器源，输入URL和自定义CSS

-### 公共服务器
-请优先在本地使用，使用公共服务器会有更大的弹幕延迟，而且服务器故障时可能出现直播事故
+以下几种方式任选一种即可。**正式使用之前记得看[注意事项](https://github.com/xfgryujk/blivechat/wiki/%E6%B3%A8%E6%84%8F%E4%BA%8B%E9%A1%B9%E5%92%8C%E5%B8%B8%E8%A7%81%E9%97%AE%E9%A2%98)**

-* [第三方公共服务器](http://chat.bilisc.com/)
-* [仅样式生成器](https://style.vtbs.moe/)
+推荐的方式：如果你需要使用插件、翻译等高级特性，则在本地使用；否则推荐直接通过公共服务器在线使用。因为本地使用时不会自动升级版本，有时候出了问题不能及时解决；但在线使用时会禁用部分高级特性，如果你有需要，只能本地使用了
+
+### 一、在线使用
+
+1. 这些是作者维护的公共服务器，根据情况随便选一个，直接用浏览器打开
+
+    * [blive.chat](https://blive.chat/)：自动节点，一般等于cn.blive.chat，如果不可用了会进行切换，但切换需要一段时间
+    * [cn.blive.chat](https://cn.blive.chat/)：墙内专用节点，不容易被墙，但如果受到攻击会变得不可用
+    * [cloudflare.blive.chat](https://cloudflare.blive.chat/)：Cloudflare美国节点，不容易被攻击，但容易被墙
+    * [vercel.blive.chat](https://vercel.blive.chat/)：Vercel美国节点，不容易被攻击，但容易被墙
+
+2. 输入主播在开始直播时获得的身份码，复制房间URL
+3. 用样式生成器生成样式，复制CSS
+4. 在OBS中添加浏览器源，输入URL和自定义CSS
+
+### 二、本地使用
+
+1. 下载[本地分发版](https://github.com/xfgryujk/blivechat/releases)（仅提供x64 Windows版）。也可以在[B站商店](https://play-live.bilibili.com/details/1694397161340)下载
+2. 双击`blivechat.exe`（或者`start.exe`）运行服务器
+3. 用浏览器打开[http://localhost:12450](http://localhost:12450)，剩下的步骤和在线使用时是一样的
+
+### 三、从源码运行
+
+此方式适用于自建服务器或者在Windows以外的平台运行
+
+1. 编译前端（需要安装Node.js）：
+
+    ```sh
+    cd frontend
+    npm i
+    npm run build
+    ```
+
+2. 运行服务器（需要安装uv）：
+
+    ```sh
+    uv run main.py
+    ```
+
+    或者可以指定host和端口号：
+
+    ```sh
+    uv run main.py --host 127.0.0.1 --port 12450
+    ```

-### 源代码版
-1. 编译前端（需要安装Node.js和npm）：
-   ```sh
-   cd frontend
-   npm i
-   npm run build
-   ```
-2. 运行服务器（需要Python3.6以上版本）：
-   ```sh
-   pip3 install -r requirements.txt
-   python3 main.py
-   ```
-   或者可以指定host和端口号：
-   ```sh
-   python3 main.py --host 127.0.0.1 --port 12450
-   ```
 3. 用浏览器打开[http://localhost:12450](http://localhost:12450)，以下略

-### Docker
-1. ```sh
-   docker run -d -p 12450:12450 xfgryujk/blivechat:latest
-   ```
+### 四、Docker
+
+此方式适用于自建服务器。示例的运行参数只是最基本的，可以根据需要修改
+
+1.  ```sh
+    docker run --name blivechat -d -p 12450:12450 \
+      --mount source=blivechat-data,target=/mnt/data \
+      xfgryujk/blivechat:latest
+    ```
+
 2. 用浏览器打开[http://localhost:12450](http://localhost:12450)，以下略
+
+## 服务器配置
+
+服务器配置文件在`data/config.ini`，可以配置数据库和允许自动翻译等，编辑后要重启生效
+
+**自建服务器时注意要删除loader_url配置**，否则加载不了房间页面
