-For all designs I ask you to make, have them be beautiful, not cookie cutter. Make webpages that are fully featured and worthy for production.
-
-By default, this template supports JSX syntax with Tailwind CSS classes, React hooks, and Lucide React for icons. Do not install other packages for UI themes, icons, etc unless absolutely necessary or I request them.
-
-Use icons from lucide-react for logos.
-
-Use stock photos from unsplash where appropriate, only valid URLs you know exist. Do not download the images, only link to them in image tags.

+  > the text needs to appear in the same line as your cursor. see screenshots ![typing in editor](task_2/screenshots/typing.png)
+- when I click the files in the code editor on sidebar, nothing happens. Fix it.
+
+  > you need to load the content of the file into the editor. see screenshots ![changing files](task_2/screenshots/changing_files.png)

+  > see screenshots ![form fields lines overlapping steps](task_3/screenshots/form_fields_lines_overlaping_steps.png)
+- On editor page, when I drag over any of form fields, I don't see them on the document. Fix it. I should be able to edit text there.
+  > see screenshots ![drag over form fields](task_3/screenshots/drag_over_form_fields.png)
