rastrillo 设计系统

设计系统所提供内容的总览。主题：signal。语言：简体中文。

日期与时间

datetime.js 增强的四个字段，每个都在底层保留原生输入控件，因此没有脚本的读者得到的是朴素的控件，而不是坏掉的控件。

预先做好、彼此一致的界面元素，在服务器端渲染。

框架自己的词汇把它们叫作 partial：ui.Templates() 返回的是 partial，docs/site/templates.md 也用这个名字。这页上的说法换了，代码里的没换。

这里的链接不可点

链接不可点，示例源码另行提供。

下面每个示例都在自己的框里。

示例内容为英文，示例外壳已翻译。

field-date

一个原生日期输入框，外加 datetime.js 启用的自然语言组合框（除非调用方传了 Plain）。试着输入「明天」。

增强输入：键入“明天”或“3 周后”
