[前端设计 Skills 分享] Make Interfaces Feel Better 把界面的"高级感"翻译成了一套可执行、可审查的量化细节规则，能系统地发现并修复那些单个不起眼、叠加起来却决定界面高级感的细节问题。 开源作者 @jakubkrehel 👍🏻 这个 Skill 的核心设计想法 细节复利：优秀界面来自小细节的叠加，而非单一亮点。 融入既有体系：修复必须用项目现有的样式方案表达（Tailwind 项目就用 Tailwind），绝不为了润色引入第二套样式系统。 慢速审查法：在浏览器动画面板以 10% 速度重放动效，并遍历 hover/focus/active/loading/empty 所有状态——慢速下感觉不对的，就是全速下隐约出错的地方。 # Skill 的十九条原则（五大类） 1. 表面与布局（Surfaces） · 同心圆角：外层圆角 = 内层圆角 + 内边距，嵌套圆角不匹配是最常见的"感觉不对"来源。 · 视觉对齐优先于几何对齐：图标按钮图标侧内边距减 2px、播放三角形右移、不对称图标直接修 SVG。 · 阴影表达层级、边框表达结构：仅为制造深度的边框应换成三层透明 box-shadow；分割线、选中/聚焦态保留边框。 · 图片描边：1px 低透明度内缩 outline，亮色模式用纯黑、暗色用纯白（oklch 10%），绝不用 slate/zinc 等带色调的近黑——会吸附底色显得脏。 · 最小点击区域：触屏 44×44px，密集桌面端至少 40×40px，可用伪元素扩展，但两个元素的热区永不重叠。 2. 动画（Animations） · 可中断性：交互动画用 CSS transition（中途可转向），keyframes 只用于一次性序列。 · 入场拆分交错：低频入场按语义分块、约 100ms 交错；高频交互（行悬停、键入）绝不加动画。 · 退场弱于入场：小固定位移（如 translateY(-12px)），时长更短（150ms），均用 ease-out。 · 图标情境动画：固定参数——scale 0.25→1、opacity 0→1、blur 4px→0；spring 的 bounce 必须为 0；无动效库时双图标同 DOM 交叉淡入淡出。 · 按压缩放：固定 scale(0.96)，不低于 0.95；提供 static prop 关闭。 · 页面加载跳过动画：AnimatePresence 加 initial={false}，但要确认不破坏有意设计的入场。 · 动效克制：动效是预算不是装饰；动效不能是唯一反馈渠道，必须配静态提示（颜色/图标/文字）。 3. 排版（Typography） · text-wrap: balance 用于标题（≤6 行），pretty 用于正文防孤词，长文本都不用。 · macOS 根布局统一加 antialiased 字体平滑。 · 动态数字用 tabular-nums 等宽数字防布局抖动；不要求更换项目字体族。 4. 图标（Icons） · 描边粗细匹配文字字重：常规文本配 1.5px，半粗配 2px。 · 单一 SVG + currentColor，状态全靠 CSS 颜色和透明度，绝不为每个状态出独立资源。 · 默认描边样式、填充样式只标记激活态；按渲染尺寸设计；RTL 场景只翻转方向性图标。 5. 性能（Performance） · 禁用 transition: all，明确列出过渡属性。 · will-change 仅用于 transform/opacity/filter，且只在观察到首帧卡顿（尤其 Safari）时才加。 审查输出规范 Skill 对审查报告有严格格式要求，这也是它区别于普通"设计建议清单"的地方： · 覆盖声明：列出五类各自实际检查了什么，未检查的必须标注"Not reviewed"，不许暗示已审。 · 发现表格：按原则分组，含严重度（HIGH/MEDIUM/LOW）、精确到行的位置、Before/After、违反的原则及用户影响。系统性问题合并为一行并列出所有受影响位置。 · 已否决候选：必须列出 1–5 个考虑过但否决的修改及理由，防止"为改而改"。 · 验证与裁决：列出实际运行的验证命令；有 HIGH 未解决则 Block，仅中低优问题则 Needs changes，无问题才 Approve。

Many have asked how this photo was made. This is my explanation. The ISS rotates about its pitch axis as it orbits Earth at 17,000mph to keep its nadir view constant. Because of this long exposure photography turns stars into arced lines. Sidereal clock drives on Earth match the planet's rotation to see stars clearly. I knew one designed for space could do this too. So a camera mount was custom built at @RITtigers to rotate once every 90 minutes using a 60 to 90 toothed gear system, cancelling out the orbital motion of ISS and allowing the capture of distant stars as fixed points! In essence, it is a a rotational coil spring powered analog star tracker. It was machined out of aluminum and is entirely mechanical to bypass NASA's strict electrical requirements for cargo. We had to get creative! After Expedition 72 it was safely returned to Earth and is to be displayed at RIT. Which I am pleased to say because a similar barn door tracker I made from spare parts on Expedition 6 for nighttime city photography was destroyed in an atmospheric trash disposal! Photography is an important part of sharing the journey to new frontiers for all people of Earth!

From China… a portable device that turns various water sources into usable, clean water China has developed a mobile water‑purification unit capable of treating well water, floodwater, river water, mountain springs, groundwater, and even tap water — all without disconnecting pipes or performing any complex installation work. The device is easy to carry and operate, making it suitable for homes, farms, work sites, camping trips, and emergency situations or natural disasters where traditional water sources are affected.
