Why do they prefer using iframe and turn on design mode by .contentWindow.document.designMode = "on" instead of directly using textarea?
The reason is that you won’t be able to live preview the styles applied using your editor in a textarea. Whenever you apply styles like pressing
Ctrl + Bthe section inside the iframe can render the characters in bold format whereas in a textarea it won’t be possible. Textarea is for entering non formatted values whereas a design mode turned on iframe is for entering formatted text.You can use any other element like div and can turn that into an editor. But using iframe you can have a separate document and can manipulate that without considering the parent page in which the iframe is set.
