+description: 应用教师端极简 SaaS 教育风（纯白画布 + 教育蓝 outline 按钮）到新页面或改造旧页面。Use when 用户要求教师端页面美化、统一按钮/输入框/间距、教育风格，或改 teacherEnd 下任意页面样式。Do not use for 学生端墨黑风或管理端深色风。
+---
+
+# 教师端 · 极简 SaaS 教育风
+
+为教师端（roleId === 3）页面套用统一视觉。**只改视觉，不动业务逻辑。**
+
+## 样式落点（先读，避免乱建文件）
+
+| 层级 | 文件 | 责任 |
+|------|------|------|
+| 全局统一外观 | [teacher-light.scss](file:///d:/TZ/dianshang-qianduan/src/assets/styles/teacher-light.scss) | 按钮、输入框、弹窗、分页、表格配色。跨页通用规则写这里 |
+| 页面自身布局 | 页面 `.vue` 的 `<style scoped>` | 布局、间距、卡片结构，引用令牌，不重复定义外观 |
+| 旧深色残留 | [AppMain.vue](file:///d:/TZ/dianshang-qianduan/src/layout/components/AppMain.vue) | 非 scoped 块里禁止再写按钮渐变（见"覆盖陷阱"） |
+
+教师端 AppMain 根节点带 `teacher-main` 类，Navbar 带 `teacher-navbar`，可作为锚点。
+
+## 设计令牌（页面根类下统一定义，全站引用）
+
+完整可复制的变量块见 [references/snippets.md](file:///d:/TZ/dianshang-qianduan/.trae/skills/teacher-edu-style/references/snippets.md)。速查：
+
+### 颜色
+
+| 令牌 | 值 | 用途 |
+|------|------|------|
+| `--edu-primary` | `#3b82f6` | 链接、描边、激活文字、图标 |
+| `--edu-primary-deep` | `#2563eb` | hover 文字、axisPointer 标签底 |
+| `--edu-primary-soft` | `#eff6ff` | 激活浅底、hover 浅底 |
+| `--text-strong` | `#1f2937` | 标题、强调正文 |
+| `--text-body` | `#6b7280` | 普通正文 |
+| `--text-muted` | `#9ca3af` | 辅助、占位符 |
+| `--border-color` | `#e5e7eb` | 卡片、输入框、分割线 |
+| 语义色 | `#ef4444` 红 / `#2ba471` 绿 / `#f59e0b` 橙 | **只**表示状态（错误/成功/警示），不做装饰 |
+
+画布纯白 `#ffffff`。禁止深色渐变背景、彩色表头、彩色按钮堆叠。
+
+### 字号（6 级，紧凑体系）
+
+| 令牌 | 值 | 用途 |
+|------|------|------|
+| `--fs-page` | `17px` | 页面标题 |
+| `--fs-card` | `14px` | 卡片标题 |
+| `--fs-body` | `12px` | 正文、按钮、输入框 |
+| `--fs-tag` | `11px` | 标签、辅助、轴标签 |
+| `--fs-kpi` | `26px` | KPI 大数字 |
+| `--fs-num` | `20px` | 行内强调数字 |
+
+字重：标题 `700`、按钮/强调 `600`、正文 `400`。行高 1.5（标题 1.35、数字 1）。
+
+### 圆角
+
+卡片 `12px`（`--r-card`）；控件/按钮/行 `8px`（`--r-control`）。
+
+## 按钮规范（重点）
+
+**统一尺寸：高 36px、横向 padding 16px、8px 圆角、12px/600、transition 0.18s。**
+
+### 主按钮 primary —— outline 风格（唯一主操作）
+
+全页最多一个，承载"查询/提交/保存/发布"。
+
+| 状态 | background | border | color |
+|------|-----------|--------|-------|
+| 默认 | `transparent` | `1px solid #3b82f6` | `#3b82f6` |
+| hover/focus | `rgba(59,130,246,0.1)` | `#3b82f6` | `#2563eb` |
+| active 按下 | `rgba(59,130,246,0.18)` | `#2563eb` | `#2563eb` |
+| disabled | 透明 | 蓝 | 蓝 + opacity .5 |
+
+无阴影、无位移。plain 朴素态同样式。写法见 snippets。
+
+### 其他按钮
+
+| 类型 | 样式 |
+|------|------|
+| 默认（取消） | 白底 + `#e5e7eb` 边 + `#1f2937` 字；hover 底 `#f9fafb`、边 `#9ca3af` |
+| success / warning / danger | 实色（绿/橙/红）白字，只用于对应语义 |
+| 表格行内文字按钮 | 透明底；primary 蓝、danger 红，无填充 |
+| is-text / is-link 的 primary | 同样收敛为 outline |
+
+### 按钮内图标
+
+- EP `.el-icon` 默认带间距；**自定义 SVG 必须显式 `gap: 8px`**，否则图标贴文字
+- 图标尺寸 `14px`，用 `currentColor` 自动跟随文字颜色（不要写死 fill）
+
+## 输入框规范（input / select / date 完全一致）
+
+| 属性 | 值 |
+|------|------|
+| 高 | `36px`（与按钮同高） |
+| 圆角 | `8px` |
+| 背景/边框 | 白底 + `1px solid #e5e7eb` |
+| hover 边 | `#d1d5db`；focus 边 `#3b82f6` + `0 0 0 3px rgba(59,130,246,0.12)` 光晕 |
+| 文字 | 12px、`#1f2937`；placeholder `#9ca3af` |
+
+**EP 关键坑：select 的边框在 `.el-select__wrapper` 上，不在 `.el-input__wrapper`。两个选择器必须同步覆盖**，否则下拉框和输入框对不齐。禁用态浅灰底 `#f3f4f6`。
+
+## 间距规范（重点）
+
+4px 基准，只允许 5 档：
+
+| 令牌 | 值 | 用途 |
+|------|------|------|
+| `--sp-1` | `4px` | 图标与紧贴文字 |
+| `--sp-2` | `8px` | 同组元素 gap、行内间距 |
+| `--sp-3` | `12px` | 分区竖向间距、卡片内分组 |
+| `--sp-4` | `16px` | 大区块 gap、卡片 padding |
+| `--sp-5` | `20px` | 页面级大分区间距 |
+
+- 卡片 padding `16px`；卡片标题与内容间距 `12px`
+- 筛选条字段间距 `12px`，字段统一宽 `200px`（`--field-w`）
+- KPI 卡行 gap `16px`；图表双栏 gap `16px`
+
+### 留白责任分层（防 padding 叠加，反复踩过）
+
+1. **app-main 自带 padding，页面根类不许再写页面级 padding/背景**
+2. 卡片、分区内部才写内容 padding
+3. 禁止在系统层（teacherLayout/main-container/app-main/app-container）为单个页面加 padding 覆盖
+4. 不允许双层 app-main + app-container 同时留白
+
+## 背景规范
+
+- 全链路（teacherLayout → main-container → app-main → app-container → 页面）在教育风页面统一纯白
+- 卡片：白底 + `1px #e5e7eb` 边 + 极淡阴影 `0 1px 3px rgba(0,0,0,0.06)`，hover 不上色（需要时轻微上浮可选）
+- 图表：`backgroundColor: "transparent"`，tooltip 白底深字
+- 图表悬停轴标签（axisPointer.label）：`#2563eb` 底 + 白字，默认浅蓝底白字看不清，必须显式设置
+
+## 表格风格规范
+
+整体：**纯白底、灰色细线、无彩色填充、无发光**。结构与层次如下。
+
+### 表格容器
+
+| 属性 | 值 |
+|------|------|
+| `background` | `#ffffff` |
+| `border` | `1px solid #e5e7eb` |
+| `border-radius` | `12px`（卡片级），`overflow: hidden` |
+| 阴影 | 无（表格已在卡片内时）或极淡 `0 1px 3px rgba(0,0,0,0.06)` |
+| CSS 变量 | `--el-table-bg-color` / `--el-table-tr-bg-color` 均 `#ffffff` |
+
+### 表头（不靠填充区分）
+
+| 属性 | 值 |
+|------|------|
+| `--el-table-header-bg-color` | `#ffffff`（禁止 `#e3effb` 等浅蓝）|
+| 表头 th 背景 | `#ffffff !important`，禁止 linear-gradient |
+| 文字 | `#1f2937`、13px、600、无 text-shadow |
+| border-bottom | `1px solid #e5e7eb`（表头与数据行唯一分界）|
+| 表头高度 | 38px；`.cell` 文字同步样式 |
+| 页面 `tableHeaderStyle` 内联对象 | 同步白底 + `#1f2937` 字 |
+
+### 数据行
+
+| 属性 | 值 |
+|------|------|
+| 行背景 | `#ffffff`（透明），禁止斑马纹彩色 |
+| 文字 | `#1f2937`、12px（`--fs-body`）|
+| 行分隔线 | `1px solid #e5e7eb`（`--el-table-border-color`）|
+| 行 hover | `#f9fafb`（中性灰，禁止浅蓝 `#eff6ff`）|
+| 单元格 padding | 纵向 12px 左右，保持紧凑 |
+| 选中/当前行 | 仅在确需时用极淡灰，不引入蓝底 |
+
+### 单元格内元素
+
+- 状态用 `el-tag`：成功绿 / 警示橙 / 信息灰，**标签本身保留语义浅底**（小面积，不影响整表白底）
+- 行内操作按钮：文字按钮透明底，primary 蓝、danger 红，按钮间 `gap: 8px`
+- 空数据：居中、`#9ca3af`、12px，不额外加色块
+
+### 分页
+
+- 白底；页码按钮灰边，当前页教育蓝底白字（小面积强调）
+- "共 N 条 / 每页条数" 文字 `#6b7280`、12px
+- 分页与表格间距 `16px`，右对齐
+
+### 落地位置
+
+跨页通用表格外观写 teacher-light.scss；页面 scoped 只做布局与列宽。注意 EP 表格变量（`--el-table-header-bg-color` 等）是注入暗色的常见入口，必须显式覆盖。
+
+## 实施步骤
+
+1. 读目标页面，确认所属层级与现有类名
+2. 通用外观缺什么补到 teacher-light.scss（按钮/输入框已覆盖时不要重复写）
+3. 页面 scoped 里只写布局与间距，全部引用令牌，硬编码色值归零
+4. 图表 tooltip / axisPointer 按本规范设置
+5. 浏览器实测：getComputedStyle 同时检查 `backgroundColor` 和 `backgroundImage`（见陷阱）
+6. Ctrl+F5 或确认 dev server 端口是最新进程
+
+## 覆盖陷阱（必读，均真实发生过）
+
+1. **background 简写污染 background-image**：旧规则 `.teacher-main .el-button--primary{background:linear-gradient(...)}` 会把渐变写进 `background-image`，只覆盖 `background-color:transparent` 无效。必须同时 `background-image:none !important`，或从源头删渐变。
+2. **陈旧 dev server**：多实例时 Vite 顺延端口（147→148），旧端口不热更新全局 scss。改了没反应先核对浏览器端口对应最新进程并重启。
+3. **select wrapper 独立**：见输入框坑。
+4. **EP `-webkit-text-fill-color`**：select 选中值可能透明，必要时显式设置。
+
+## 完成验证清单
+
+- [ ] 无硬编码色值（除语义状态、3px 装饰条、图表内模板）
+- [ ] 按钮：透明蓝边默认态 + 半蓝 hover + 无渐变（background-image: none）
+- [ ] 输入框与按钮同高 36px，input/select/date 外观一致
+- [ ] 间距只用 5 档令牌，无随意像素值
+- [ ] 字号只用 6 级令牌
+- [ ] 页面根类无重复 padding/背景
+- [ ] GetDiagnostics 无报错
+- [ ] 真实鼠标验证 hover / 轴标签可读性

+
+## 1. 页面根类令牌块（放 scoped 顶部）
+
+```scss
+.xxx-page {
+  /* 颜色 */
+  --edu-primary: #3b82f6;
+  --edu-primary-deep: #2563eb;
+  --edu-primary-soft: #eff6ff;
+  --text-strong: #1f2937;
+  --text-body: #6b7280;
+  --text-muted: #9ca3af;
+  --border-color: #e5e7eb;
+
+  /* 字号 */
+  --fs-page: 17px;
+  --fs-card: 14px;
+  --fs-body: 12px;
+  --fs-tag: 11px;
+  --fs-kpi: 26px;
+  --fs-num: 20px;
+
+  /* 间距（4px 基准）*/
+  --sp-1: 4px;
+  --sp-2: 8px;
+  --sp-3: 12px;
+  --sp-4: 16px;
+  --sp-5: 20px;
+
+  /* 圆角 / 控件 */

+  --r-control: 8px;
+  --control-h: 36px;
+  --field-w: 200px;
+  --btn-pad-x: 16px;
+  --btn-icon: 14px;
+}
+```
+
+## 2. 主按钮 outline（页面 scoped 本地强制版）
+
+当全局未接管或需保证单页一定生效时使用：
+
+```scss
+.search-btn {
+  height: var(--control-h);
+  padding: 0 var(--btn-pad-x);
+  background-color: transparent !important;
+  background-image: none !important; /* 关键：清渐变层 */
+  border: 1px solid var(--edu-primary) !important;
+  color: var(--edu-primary) !important;
+  border-radius: var(--r-control) !important;
+  box-shadow: none !important;
+  font-size: var(--fs-body);
+  font-weight: 600;
+  gap: var(--sp-2); /* 自定义 SVG 图标间距 */
+  transition: background-color 0.18s ease, color 0.18s ease;
+
+  &:hover,
+  &:focus {
+    background-color: rgba(59, 130, 246, 0.1) !important;
+    color: var(--edu-primary-deep) !important;
+  }
+
+  &:active {
+    background-color: rgba(59, 130, 246, 0.18) !important;
+    color: var(--edu-primary-deep) !important;
+  }
+
+  .btn-svg {
+    width: var(--btn-icon);
+    height: var(--btn-icon);
+    /* SVG 内 fill / stroke 用 currentColor */
+  }
+}
+```
+
+## 3. 输入框 / 下拉 / 日期 统一覆盖（teacher-light.scss 通用）
+
+```scss
+.el-input__wrapper,
+.el-select__wrapper {
+  height: 36px !important;
+  background-color: #ffffff !important;
+  border-radius: 8px !important;
+  box-shadow: 0 0 0 1px #e5e7eb inset !important;
+  padding: 0 11px !important;
+  transition: box-shadow 0.18s ease;
+
+  &:hover {
+    box-shadow: 0 0 0 1px #d1d5db inset !important;
+  }
+
+  &.is-focus,
+  &:focus-within {
+    box-shadow: 0 0 0 1px #3b82f6 inset,
+      0 0 0 3px rgba(59, 130, 246, 0.12) !important;
+  }
+}
+
+.el-input__inner,
+.el-select__selected-item {
+  font-size: 12px;
+  color: #1f2937;
+  -webkit-text-fill-color: #1f2937;
+}
+
+.el-input__inner::placeholder {
+  color: #9ca3af;
+  -webkit-text-fill-color: #9ca3af;
+}
+```
+
+## 4. 卡片
+
+```scss
+.card {
+  background: #ffffff;
+  border: 1px solid var(--border-color);
+  border-radius: var(--r-card);
+  box-shadow: 0 1px 3px rgba(0, 0, 0, 0.06);
+  padding: var(--sp-4);
+
+  &-title {
+    font-size: var(--fs-card);
+    font-weight: 700;
+    color: var(--text-strong);
+    margin: 0 0 var(--sp-3);
+  }
+}
+```
+
+## 5. 走势图 tooltip + axisPointer（ECharts option）
+
+```js
+tooltip: {
+  trigger: "axis",
+  backgroundColor: "rgba(255, 255, 255, 0.98)",
+  borderColor: "rgba(59, 130, 246, 0.2)",
+  borderWidth: 1,
+  padding: [10, 14],
+  textStyle: { color: "#1f2937", fontSize: 13 },
+  axisPointer: {
+    type: "cross",
+    lineStyle: { color: "rgba(59,130,246,0.3)", type: "dashed" },
+  },
+},
+xAxis: {
+  // ...
+  axisPointer: {
+    label: {
+      backgroundColor: "#2563eb",
+      color: "#ffffff",
+      fontSize: 11,
+      fontWeight: 600,
+      padding: [4, 8],
+      borderRadius: 4,
+    },
+  },
+},
+yAxis: {
+  // ...
+  axisPointer: {
+    label: { backgroundColor: "#2563eb", color: "#ffffff", fontSize: 11 },
+  },
+},
+```
+
+## 6. 饼图 tooltip（item 触发）
+
+```js
+tooltip: {
+  trigger: "item",
+  backgroundColor: "rgba(255, 255, 255, 0.98)",
+  borderColor: "rgba(59, 130, 246, 0.2)",
+  textStyle: { color: "#1f2937", fontSize: 13 },
+  formatter: "{b}: {c}人 ({d}%)",
+},
+```
+
+## 7. 页面骨架参考
+
+```html
+<div class="xxx-page">
+  <!-- 页面标题（app-main 已提供 padding，这里不加）-->
+  <header class="page-head">
+    <h1 class="page-title">页面标题</h1>
+    <p class="page-sub">辅助说明</p>
+  </header>
+
+  <!-- KPI 行 -->
+  <div class="kpi-row">
+    <div class="kpi-card"><!-- 图标 + 标签 + 大数字 --></div>
+  </div>
+
+  <!-- 内容区 -->
+  <div class="content-grid">
+    <section class="card">...</section>
+  </div>
+</div>
+```
+
+## 8. 浏览器快速自检脚本（DevTools / browser_evaluate）
+
+```js
+const btn = document.querySelector(".search-btn");
+const s = getComputedStyle(btn);
+({
+  backgroundColor: s.backgroundColor, // rgba(0,0,0,0)
+  backgroundImage: s.backgroundImage, // 必须 none
+  borderColor: s.borderColor,         // rgb(59,130,246)
+  color: s.color,                     // rgb(59,130,246)
+  height: s.height,                   // 36px
+});
+```
