Component Styling - 组件样式规范

车险签单数据分析平台的组件样式模板和BEM命名规范。

🧩 组件样式模板

1. 卡片样式 (Card)

基础卡片模板:

<template>
  <div class="card">
    <div class="card__header">
      <h3 class="card__title">{{ title }}</h3>
      <p class="card__subtitle">{{ subtitle }}</p>
    </div>
    <div class="card__body">
      <slot></slot>
    </div>
    <div class="card__footer">
      <slot name="footer"></slot>
    </div>
  </div>
</template>

<style scoped>
.card {
  background: var(--surface-elevated);
  border-radius: var(--radius-md);
  box-shadow: var(--shadow-soft);
  padding: var(--space-6);
  transition: box-shadow 0.3s ease;
}

.card:hover {
  box-shadow: 0 15px 40px rgba(15, 23, 42, 0.12);
}

.card__header {
  margin-bottom: var(--space-4);
  border-bottom: 1px solid var(--gray-300);
  padding-bottom: var(--space-3);
}

.card__title {
  font-size: var(--text-xl);
  font-weight: 600;
  color: var(--text-primary);
  margin: 0;
}

.card__subtitle {
  font-size: var(--text-sm);
  color: var(--text-secondary);
  margin: var(--space-2) 0 0;
}

.card__body {
  margin-bottom: var(--space-4);
}

.card__footer {
  padding-top: var(--space-3);
  border-top: 1px solid var(--gray-300);
}
</style>

2. 按钮样式 (Button)

按钮变体模板:

<template>
  <button :class="['btn', `btn--${variant}`, `btn--${size}`]">
    <slot></slot>
  </button>
</template>

<script setup>
defineProps({
  variant: {
    type: String,
    default: 'primary',
    validator: (v) => ['primary', 'secondary', 'ghost'].includes(v)
  },
  size: {
    type: String,
    default: 'md',
    validator: (s) => ['sm', 'md', 'lg'].includes(s)
  }
})
</script>

<style scoped>
/* 基础样式 */
.btn {
  display: inline-flex;
  align-items: center;
  justify-content: center;
  border: none;
  border-radius: var(--radius-sm);
  font-family: var(--font-family-base);
  font-weight: 500;
  cursor: pointer;
  transition: all 0.2s ease;
}

.btn:disabled {
  opacity: 0.5;
  cursor: not-allowed;
}

/* 尺寸变体 */
.btn--sm {
  padding: var(--space-2) var(--space-3);
  font-size: var(--text-sm);
}

.btn--md {
  padding: var(--space-3) var(--space-5);
  font-size: var(--text-base);

}

.btn--ghost:hover:not(:disabled) {
  background: var(--surface-primary-tint);
}
</style>

3. 表单控件 (Form Controls)

输入框模板:

<template>
  <div class="input-group">
    <label v-if="label" class="input-group__label">{{ label }}</label>
    <input
      :type="type"
      :placeholder="placeholder"
      :value="modelValue"
      @input="$emit('update:modelValue', $event.target.value)"
      class="input-group__input"
    />
    <span v-if="error" class="input-group__error">{{ error }}</span>
  </div>
</template>

<script setup>
defineProps({
  label: String,
  type: { type: String, default: 'text' },
  placeholder: String,
  modelValue: [String, Number],
  error: String
})

defineEmits(['update:modelValue'])
</script>

<style scoped>
.input-group {
  display: flex;
  flex-direction: column;
  gap: var(--space-2);

  font-size: var(--text-xs);
  color: var(--status-warning);
}
</style>

4. 图表容器 (Chart Container)

ECharts容器模板:

<template>
  <div class="chart-container">
    <div class="chart-container__header">
      <h4 class="chart-container__title">{{ title }}</h4>
      <div class="chart-container__actions">
        <slot name="actions"></slot>
      </div>
    </div>
    <div class="chart-container__body">
      <div ref="chartRef" class="chart-container__canvas"></div>

.chart-container__body {
  position: relative;
}

.chart-container__canvas {
  width: 100%;
  height: 400px;  /* 必须设置高度 */
}
</style>

🏷️ BEM 命名规范

基础规则

命名格式:

  • Block: .block
  • Element: .block__element
  • Modifier: .block--modifier 或 .block__element--modifier

分隔符:

  • __ (双下划线): 元素分隔符
  • -- (双中划线): 修饰符分隔符
  • - (单中划线): 词语分隔符(多个单词)

KPI 卡片示例

<!-- Block -->
<div class="kpi-card">

  <!-- Element -->
  <div class="kpi-card__header">
    <h3 class="kpi-card__title">签单保费</h3>
  </div>

  <!-- Element -->
  <div class="kpi-card__main">
    <div class="kpi-card__value">1,234,567</div>

    <!-- Element + Modifier -->
    <div class="kpi-card__trend kpi-card__trend--up">
      <span class="kpi-card__trend-icon">↑</span>
      <span class="kpi-card__trend-text">+12.5%</span>
    </div>
  </div>

  <!-- Element -->
  <div class="kpi-card__chart">
    <div class="kpi-card__chart-canvas"></div>
  </div>

</div>

CSS:

/* Block */
.kpi-card {
  /* ... */
}

/* Element */
.kpi-card__header { /* ... */ }
.kpi-card__title { /* ... */ }
.kpi-card__main { /* ... */ }
.kpi-card__value { /* ... */ }
.kpi-card__trend { /* ... */ }
.kpi-card__trend-icon { /* ... */ }
.kpi-card__trend-text { /* ... */ }
.kpi-card__chart { /* ... */ }
.kpi-card__chart-canvas { /* ... */ }

/* Modifier */
.kpi-card__trend--up {
  color: var(--status-success);
}
.kpi-card__trend--down {
  color: var(--status-warning);
}
.kpi-card__trend--neutral {
  color: var(--status-neutral);
}

命名示例表

场景正确 ✅错误 ❌
块.card.Card, .CARD
元素.card__header.card-header, .cardHeader
修饰符.card--large.card-large, .cardLarge
多词元素.card__price-tag.card__priceTag, .card__price_tag
状态修饰符.button--disabled.button-disabled, .disabled

常见反模式

❌ 避免过深嵌套:

<!-- 不推荐 -->
<div class="card">
  <div class="card__header">
    <div class="card__header__title">
      <span class="card__header__title__text">标题</span>  <!-- 4层嵌套 -->
    </div>
  </div>
</div>

✅ 扁平化元素:

<!-- 推荐 -->
<div class="card">
  <div class="card__header">
    <div class="card__title">
      <span class="card__title-text">标题</span>  <!-- 2层嵌套 -->
    </div>
  </div>
</div>

📱 响应式设计

断点系统

3级断点:

/* 移动端 (默认) */
@media (max-width: 767px) {
  /* Mobile styles */
}

/* 平板端 */
@media (min-width: 768px) and (max-width: 1023px) {
  /* Tablet styles */
}

/* 桌面端 */
@media (min-width: 1024px) {
  /* Desktop styles */
}

Dashboard 布局示例

移动端 (单列):

/* 移动端(默认) */
.dashboard {
  display: flex;
  flex-direction: column;
  gap: var(--space-4);
  padding: var(--space-4);
}

.dashboard__kpi-grid {
  display: grid;
  grid-template-columns: 1fr;  /* 单列 */
  gap: var(--space-4);
}

平板端 (2列):

@media (min-width: 768px) {
  .dashboard {
    padding: var(--space-6);
  }

  .dashboard__kpi-grid {
    grid-template-columns: repeat(2, 1fr);  /* 2列 */
  }
}

桌面端 (3列):

@media (min-width: 1024px) {
  .dashboard {
    padding: var(--space-8);
  }

  .dashboard__kpi-grid {
    grid-template-columns: repeat(3, 1fr);  /* 3列 */
  }
}

响应式字体

流式字体:

.kpi-card__value {
  font-size: clamp(1.5rem, 4vw, 2.5rem);
  /* 最小24px, 理想4vw, 最大40px */
}

断点字体:

.heading {
  font-size: var(--text-xl);  /* 移动端: 20px */
}

@media (min-width: 768px) {
  .heading {
    font-size: var(--text-2xl);  /* 平板: 24px */
  }
}

@media (min-width: 1024px) {
  .heading {
    font-size: var(--text-3xl);  /* 桌面: 30px */
  }
}

✅ 最佳实践

1. Scoped 样式

<!-- ✅ 正确 -->
<style scoped>
.kpi-card {
  /* 样式只作用于当前组件 */
}
</style>

<!-- 穿透子组件时使用 :deep() -->
<style scoped>
.parent :deep(.child) {
  color: red;
}
</style>

2. BEM 命名

/* ✅ 正确 */
.kpi-card { }
.kpi-card__header { }
.kpi-card__title { }
.kpi-card__value--up { }

/* ❌ 错误 */
.card { }
.cardHeader { }

3. 响应式设计 (移动优先)

/* ✅ 推荐: 移动优先 */
.grid {
  grid-template-columns: 1fr;  /* 移动端默认 */
}

@media (min-width: 768px) {
  .grid {
    grid-template-columns: repeat(2, 1fr);  /* 平板 */
  }
}

/* ❌ 不推荐: 桌面优先 */
.grid {
  grid-template-columns: repeat(3, 1fr);
}

@media (max-width: 1023px) {
  .grid {
    grid-template-columns: repeat(2, 1fr);
  }
}

关键文档位置

相关 Skills

外部参考

✅ 总结

核心要点

  1. 组件模板: 卡片/按钮/表单/图表容器
  2. BEM命名: .block__element--modifier
  3. 响应式: 移动优先, 768px / 1024px断点
  4. Scoped CSS: 避免样式污染
  5. CSS变量: 使用设计Token,不硬编码

适用场景

✅ 适用:

  • 创建新组件样式
  • 修改现有组件样式
  • 实现响应式布局
  • BEM命名规范

❌ 不适用(请使用其他Skills):

  • 定义CSS变量 → css-design-tokens
  • Vue组件逻辑 → vue-component-dev
