Render-blocking requests

Est savings of 400 ms

Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.

01 / 值得借鉴

好设计,具体好在哪

真实界面解释产品范围

同一项目面板同时露出消息、文件、任务与日历,让协作范围具体可见。

链接有补充说明

桌面链接清单在名称后附短句,用户不必逐项打开才知道将看到什么。

02 / 下一步

值得继续打磨的地方

  1. 01

    手机产品截图需支持读细节

    完整桌面工作区缩到手机宽度后,面板文字很难辨认。

    保留整体截图,同时提供可放大的静态预览或按功能拆开的局部图;不要仅靠一张缩小图解释所有能力。

03 / 设计语言

把气质拆成可复用的参数

色彩

背景

#fcf7ff

#29353c

强调

字体与尺度

标题字体
Graphik

按钮圆角

参数来自页面元素采样,空值表示未取得;不将单个元素的参数当作全站规范。

04 / 检查依据

观察与实测依据

数据来自同次页面采集;字体、圆角和间距为具体元素采样,不代表全站唯一设计规范。空值为未取得。HTML 为源码体积,不是压缩传输量;脚本数为 DOM 标签数,不是请求数。

没有 HSTS 响应头

中优先级

没有 Strict-Transport-Security,第一次访问仍可能被降到 http。浏览器不会钉死 HTTPS。

在边缘设置 Strict-Transport-Security: max-age=31536000; includeSubDomains。

strict-transport-security missing

没有 Content-Security-Policy

CSP 是限制脚本源的标准做法。vibe 页面常常什么都加载,包括被注入的脚本。

先开 report-only CSP,再收成 default-src 'self' 和明确的 script-src。

content-security-policy missing

没有 X-Content-Type-Options

没有 nosniff,浏览器可能按错误类型解释文件。这是一行响应头。

设置 X-Content-Type-Options: nosniff。

x-content-type-options missing

没有 Referrer-Policy

默认 referrer 可能把站内路径和查询串漏给第三方。

设置 Referrer-Policy: strict-origin-when-cross-origin。

referrer-policy missing

设计基线
桌面左侧以链接清单介绍价格、版本、功能与理念,右侧直接展示消息板、文件、任务、聊天与日历的项目视图;大标题说明简单可靠的定位,之后进入评价与产品说明。手机将标题和导览入口放前面,再展示项目截图。复刻重点是信息密度和实际产品证据。

执行事项
1. 手机产品截图需支持读细节
保留整体截图,同时提供可放大的静态预览或按功能拆开的局部图;不要仅靠一张缩小图解释所有能力。
依据: mobile.png: desktop project overview scaled to phone width

2. 没有 HSTS 响应头
在边缘设置 Strict-Transport-Security: max-age=31536000; includeSubDomains。
依据: strict-transport-security missing

3. 没有 Content-Security-Policy
先开 report-only CSP,再收成 default-src 'self' 和明确的 script-src。
依据: content-security-policy missing

4. 没有 X-Content-Type-Options
设置 X-Content-Type-Options: nosniff。
依据: x-content-type-options missing

5. 没有 Referrer-Policy
设置 Referrer-Policy: strict-origin-when-cross-origin。
依据: referrer-policy missing

验收
- 在 1440×900 和 390×844 分别核对文字、布局和主要操作“Sign up free”。
- 保留已有品牌、登录和业务链路,不从静态截图推断交互故障。
- 只修复有证据的项;涉及安全响应头时先用报告模式验证现有资源及认证兼容性。
- 对比修改前后的截图,并执行相关功能测试。不要声称未经测试的功能已通过。
