问题 I am using TinyMCE to provide a rich text editing text editor. But the line spacing between the lines is too much. I have added a screenshot that shows the line spacing I get on pressing an enter.

But you can override in the css class: .tinymce-content p { padding: 0; margin: 2px 0; } See the tinymce docs

问题 While working on a WinForm application, I would like to split a long text (only characters, no images, no special format) into multiple pieces (pages), in order to fit them into a RichTextBox . The problem is that RichTextBox doesn't support multiple pages. I have to write my own algorithm (some kind of DP programming) to split the text.
