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:

/* (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;
}

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:

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:

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。
