Download the CKEditor library from the official website (https://ckeditor.com/ckeditor-4/download/).
Extract the downloaded archive and copy the "ckeditor" directory to your website's root directory or any other location that is accessible by your website.
Include the CKEditor library in your HTML file by adding the following code to the head of your HTML document:
- Create a textarea element in your HTML form where you want to use the CKEditor:
<textarea name="content" id="content"></textarea>
**CKEDITOR.replace** function takes the ID of the textarea element as a parameter and replaces it with the CKEditor instance.
- Save the changes to your HTML file and load it in a web browser to see the CKEditor in action.
And that's it! You now have CKEditor integrated into your website and ready to be used by your users. You can customize the appearance and behavior of the editor by configuring its settings and creating custom plugins if needed.
