富内容编辑器在理想情况下，应该能生成干净、语义明确的文档，同时仍然让用户易于理解。ProseMirror 试图弥合编辑明确、无歧义的内容（如 Markdown 或 XML）与经典的 所见即所得（WYSIWYG）编辑器之间的鸿沟。
Rich content editors should, ideally, produce clean, semantically meaningful documents while still being easy for users to understand. ProseMirror tries to bridge the gap between editing explicit, unambiguous content like Markdown or XML, and classical WYSIWYG editors.
它通过为比普通 HTML 更受约束、更有结构的文档实现一个所见即所得风格的编辑界面来做到这一点。你可以自定义编辑器所创建文档的形状和结构，并根据你的应用需求来调整它们。
It does this by implementing a WYSIWYG-style editing interface for documents more constrained and structured than plain HTML. You can customize the shape and structure of the documents your editor creates, and tailor them to your application's needs.
