**In this code, we create a simple, professional To-Do List application. It includes a container with a header, an input field for adding tasks, and a list to display tasks. Each task is displayed with a delete button to remove it from the list.

The JavaScript code handles adding tasks when the "Enter" key is pressed or when the "Add" button is clicked. The tasks are dynamically generated and displayed in the list.

Feel free to enhance and customize the design and features of this To-Do List app to fit your specific needs and desired level of professionalism.**
