|
* CKEditor is an online rich text editor that can be embedded inside web pages.
|
|
29
|
* It is a WYSIWYG (What You See Is What You Get) editor which means that the
|
|
30
|
* text edited in it looks as similar as possible to the results end users will
|
|
31
|
* see after the document gets published. It brings to the Web popular editing
|
|
32
|
* features found in desktop word processors such as Microsoft Word and
|
|
33
|
* OpenOffice.org Writer. CKEditor is truly lightweight and does not require any
|
|
34
|
* kind of installation on the client computer.
