前言

記錄讓c4 從scss 轉為 原子css unocss

🎯 方案一：混合模式 (推薦)

保留語義化的 SCSS 類名，內部使用 @apply 指令應用 UnoCSS：

讓我展示如何重構為語義化的 SCSS + UnoCSS 混合模式：

<template><view class="page"><view class="tab-bar"><viewv-for="(tab, index) in tabList":key="tab.key"class="tab-item":class="{ 'active': currentTab === index }"@click="changeTab(index)"><text class="tab-text">{{ tab.label }}</text><text class="tab-count">({{ tab.count }})</text></view></view><!-- 成員列表 --><view class="content"><scroll-view scroll-y class="scroll-container"><view class="member-list"><viewv-for="member in currentMemberList":key="member.id"class="member-item"><view class="member-info"><image :src="member.avatar" class="avatar" mode="aspectFill" /><view class="info">xxx</view></view></view><view class="delete-btn" @click="deleteMember(member.id)">刪除</view></view><!-- 空狀態 --><view v-if="currentMemberList.length === 0" class="empty-state"><image src="/static/images/mine/no_list.webp" class="empty-icon" mode="aspectFit" /><text class="empty-text">暫無成員</text></view></view></scroll-view></view></view>
</template><style lang="scss" scoped>
/* 使用 @apply 指令結合 UnoCSS */
.page {@apply min-h-screen flex flex-col bg-#f7f7f7;
}.tab-bar {@apply bg-white flex px-32rpx border-b-2rpx border-#f5f5f5;
}.member-item {@apply flex items-center justify-between h-174rpx bg-white rounded-20rpx px-32rpx mb-24rpx;box-shadow: 0 2rpx 8rpx rgba(0, 0, 0, 0.06);
}.add-text {@apply text-32rpx font-600 text-white;
}.modal-overlay {@apply fixed top-0 left-0 right-0 bottom-0 z-1000 flex items-center justify-center p-40rpx bg-black bg-opacity-50;
}/* 其他彈窗樣式... */
</style>

🎯 方案二：語義化組件類

創建語義化的組件類，內部使用 UnoCSS：

<template><view class="member-management-page"><view class="navigation-tabs"><view class="tab-item" :class="{ 'is-active': currentTab === index }"><!-- 內容 --></view></view><view class="member-content"><view class="member-card"><view class="member-basic-info"><!-- 成員信息 --></view><view class="member-actions"><!-- 操作按鈕 --></view></view></view><view class="floating-add-section"><view class="primary-add-button"><!-- 添加按鈕 --></view></view></view>
</template><style lang="scss" scoped>
.member-management-page {@apply min-h-screen flex flex-col bg-#f7f7f7;
}.navigation-tabs {@apply bg-white flex px-32rpx border-b-2rpx border-#f5f5f5;
}.tab-item {@apply flex-1 py-32rpx relative flex items-center justify-center gap-8rpx cursor-pointer;&.is-active {&::after {content: '';position: absolute;bottom: 0;left: 50%;transform: translateX(-50%);width: 40rpx;height: 4rpx;background: #ff6600;border-radius: 2rpx;}}
}.member-content {@apply flex-1 flex flex-col;
}.member-card {@apply flex items-center justify-between h-174rpx bg-white rounded-20rpx px-32rpx mb-24rpx;box-shadow: 0 2rpx 8rpx rgba(0, 0, 0, 0.06);
}.member-basic-info {@apply flex items-center flex-1 gap-24rpx mr-24rpx;
}.member-actions {@apply min-w-88rpx py-16rpx bg-white rounded-24rpx text-24rpx font-500 text-center flex-shrink-0 cursor-pointer transition-all-300ms;
}.floating-add-section {@apply fixed bottom-0 left-0 right-0 bg-white rounded-t-48rpx px-32rpx pt-24rpx pb-120rpx;box-shadow: 0 -4rpx 20rpx rgba(0, 0, 0, 0.06);
}.primary-add-button {@apply w-full h-88rpx flex items-center justify-center bg-#ff6600 rounded-44rpx cursor-pointer transition-all-300ms;box-shadow: 0 8rpx 24rpx rgba(255, 102, 0, 0.3);&:active {@apply opacity-90 scale-98;}
}
</style>

🎯 方案三：CSS 模塊化

使用 CSS 變量 + 語義化類名：

<template><view class="page"><view class="tab-bar"><view class="tab-item" :class="{ 'active': currentTab === index }"><!-- 內容 --></view></view></view>
</template><style lang="scss" scoped>
:root {--primary-color: #ff6600;--text-primary: #333333;--text-secondary: #666666;--text-placeholder: #999999;--bg-page: #f7f7f7;--bg-card: #ffffff;--border-light: #f5f5f5;--shadow-card: 0 2rpx 8rpx rgba(0, 0, 0, 0.06);--shadow-floating: 0 -4rpx 20rpx rgba(0, 0, 0, 0.06);--radius-small: 20rpx;--radius-medium: 24rpx;--radius-large: 48rpx;
}.page {min-height: 100vh;display: flex;flex-direction: column;background: var(--bg-page);
}.tab-bar {background: var(--bg-card);display: flex;padding: 0 32rpx;border-bottom: 2rpx solid var(--border-light);
}.tab-item {flex: 1;padding: 32rpx 0;position: relative;display: flex;align-items: center;justify-content: center;gap: 8rpx;cursor: pointer;&.active::after {content: '';position: absolute;bottom: 0;left: 50%;transform: translateX(-50%);width: 40rpx;height: 4rpx;background: var(--primary-color);border-radius: 2rpx;}
}.member-item {display: flex;align-items: center;justify-content: space-between;height: 174rpx;background: var(--bg-card);border-radius: var(--radius-small);padding: 0 32rpx;margin-bottom: 24rpx;box-shadow: var(--shadow-card);
}.add-button-wrapper {position: fixed;bottom: 0;left: 0;right: 0;background: var(--bg-card);border-radius: var(--radius-large) var(--radius-large) 0 0;padding: 24rpx 32rpx 120rpx;box-shadow: var(--shadow-floating);
}
</style>

🎯 方案四：BEM 命名規范

使用 BEM 命名約定保持語義性：

<template><view class="member-page"><view class="member-page__tabs"><view class="member-page__tab member-page__tab--active"><!-- 標簽內容 --></view></view><view class="member-page__content"><view class="member-card"><view class="member-card__info"><view class="member-card__avatar"></view><view class="member-card__details"><view class="member-card__name-section"><!-- 姓名和編輯 --></view><view class="member-card__address-section"><!-- 地址和復制 --></view></view></view><view class="member-card__actions"><!-- 刪除按鈕 --></view></view></view><view class="member-page__floating-actions"><button class="member-page__add-btn"><!-- 添加按鈕 --></button></view></view>
</template><style lang="scss" scoped>
.member-page {@apply min-h-screen flex flex-col bg-#f7f7f7;&__tabs {@apply bg-white flex px-32rpx border-b-2rpx border-#f5f5f5;}&__tab {@apply flex-1 py-32rpx relative flex items-center justify-center gap-8rpx cursor-pointer;&--active::after {content: '';position: absolute;bottom: 0;left: 50%;transform: translateX(-50%);width: 40rpx;height: 4rpx;background: #ff6600;border-radius: 2rpx;}}&__content {@apply flex-1 flex flex-col;}&__floating-actions {@apply fixed bottom-0 left-0 right-0 bg-white rounded-t-48rpx px-32rpx pt-24rpx pb-120rpx;box-shadow: 0 -4rpx 20rpx rgba(0, 0, 0, 0.06);}&__add-btn {@apply w-full h-88rpx flex items-center justify-center bg-#ff6600 rounded-44rpx cursor-pointer transition-all-300ms;box-shadow: 0 8rpx 24rpx rgba(255, 102, 0, 0.3);&:active {@apply opacity-90 scale-98;}}
}.member-card {@apply flex items-center justify-between h-174rpx bg-white rounded-20rpx px-32rpx mb-24rpx;box-shadow: 0 2rpx 8rpx rgba(0, 0, 0, 0.06);&__info {@apply flex items-center flex-1 gap-24rpx mr-24rpx;}&__avatar {@apply w-88rpx h-88rpx rounded-20rpx flex-shrink-0;}&__details {@apply flex-1;}&__name-section {@apply flex items-center gap-12rpx mb-12rpx;}&__address-section {@apply flex items-center gap-8rpx;}&__actions {@apply min-w-88rpx py-16rpx bg-white rounded-24rpx text-24rpx font-500 text-center flex-shrink-0 cursor-pointer transition-all-300ms;color: var(--text-placeholder);&:active {@apply bg-#f8f8f8 text-#333333;}}
}
</style>

💡 推薦做法

方案一（混合模式），因為它：

1. 保持語義性: 類名清晰表達組件功能
2. 利用 UnoCSS: 通過 @apply 獲得原子化 CSS 的好處
3. 易于維護: 樣式集中管理，便于修改
4. 性能優化: 結合兩種方案的優勢
5. 團隊友好: 新成員容易理解代碼結構
