- 运行例子：标题带每个例子的对错胶囊，全对时提示「再按提交」
- 自己输入：说明「这里不判对错」，输出框留出固定高度
- Python 报错：灰底卡片，改法按钮放显眼处
- 流程图点评：画过几次连成一排，大分数 + 等级 + 四项分数条，重新提交后直接显示新的这一次
- 工具栏「写代码 / 画流程图」换成设计稿的分段切换，窄时缩成「代码 / 流程图」
- 设计文档记下和画板有意不同的几处（去掉限时、保留新轮盘等）

 # OJ2 设计文档：题目详情页重设计
 
 日期：2026-09-28
-状态：**第 14 节的 6 步和第 7 节都已实施**（2026-09-28）。和本文有出入的地方：协作中上下文条的跳转没有改成开新标签（老师不在课堂名单里，题库入口下这一条本来就不出现）。效果图在 claude.ai 的私有画布「题目详情页重设计」里（「机房（方案 B）」
-那一页是定稿，「初稿 1280×800」那一页已作废，只留着对照）。效果图表达不了的规则都写在这里，

+和画板有意不同的几处（都是拍过板的）：
+
+- 题面**不写时间和内存限制**（画板上有「限时 1 秒」）：用户 2026-09-28 拍板，中职学生看了反而迷惑。
+- 点评用重新设计过的 SVG 轮盘（第 7 节），不是画板上的样子。
+- 流程图编辑器内部（节点库、撤销重做那一排）沿用原来的布局，没照画板重排。
+- 「交之前检查」那一段不带时间；「运行例子」的结果胶囊在窄屏会折行。
 
 题目页是全站的核心页面：学生在这一页读题、写代码、提交、看结果、改、去下一题，老师在这一页
 接求助、协作。动它之前先把第 12 节「旧功能 → 新位置」对一遍，不能漏。
