Could you please explain how the text in the textarea gets styled in rich-text editors? I ve tried to style text in the form but it doesn t change.
Is it JS that recognizes characters typed by the user? How s that done?
After a bit of research (Google rules!), I ve found some excellent information. For others who might be interested, these links were very helpful to me:
I think the answer is that what you re looking at is typically NOT an actual <textarea>. It s a <div> or <span> made to look like a text area. A regular HTML textarea doesn t have individual formatting of the text.
"Rich-Text editors" will have controls that modify the contents of the span/div with regular html markup (<strong>, <em>, etc.) to emulate a full-blown rich text editor
Usually, the rich text editor will provide a variable to specify a style sheet in. That style sheet will then be loaded and applied to the textarea (Most, if not all, rich text editors use a IFRAME to display the editor in, and obviously styles specified in the main document won t apply to it.)
It s a textarea when you send the HTML to the user but the editor replaced it with a div when it can start.
This way, the code gracefully degrades: Users with unsupported web browsers or disabled JavaScript can still edit the text in the textarea while all the other users get a nice rich text editor.
Basically, the TEXTAREA contents are used as the HTML source for the IFRAME.
