It must be a pain to make a text box with the ability to add bold, italic, heading, etc. you know? All the bold text, italics, and headings would need to be saved in a database column to be retrieved later in their correct positions.
I don’t know, I am doing internship learning C# ASP (started 2 months ago), and just got a “Shower Thought” while making an edit post function.
You can always take a look how for example Windows 3.11 and earlier did it for their *.rtf file format and their “write.exe” editor / viewer / renderer (if you want to call it that way).
