Text Before HTML:

We are going to create a Kanban board for task management with the following features:
 1. Draggable tasks: We'll use HTML5 drag and drop API.
 2. Color-coded categories: Each category (e.g., To Do, In Progress, Done) will have a distinct color.
 3. Progress indicators: Each task card will show a progress bar or indicator.

 We'll structure the board into columns (categories). Each column will have a header with the category name and a color, and a list of tasks.

 Steps:
 - We'll have a container for the board (flex or grid).
 - Each column is a droppable area.
 - Each task is a draggable card.

 We'll use Tailwind CSS for styling. We'll choose a color scheme that is professional and clean.

 Let's define:
   - Primary color: blue (for accents and progress)
   - Background: light gray for the board, white for the cards.

 We'll use the following structure:

   

     
  
        
To Do
        

          
Task 1
          ... more tasks ...
        
     
     ... more columns ...
   

 For the progress indicator, we can use a simple text or a bar. Since each task might have a progress percentage, we can show a small bar next to the task title.

 We'll also add a form to add new tasks.

 Let's plan the data structure for tasks:

   tasks = [
     { id: 1, title: "Task 1", category: "todo", progress: 0 },
     { id: 2, title: "Task 2", category: "inprogress", progress: 50 },
     { id: 3, title: "Task 3", category: "done", progress: 100 }
   ]

 We'll use JavaScript to handle drag and drop and to update the progress.

 However, note: The problem says to use Tailwind HTML CSS. We are to output a single HTML file.

 We'll include:
   - Tailwind via CDN
   - Custom styles for the drag and drop and progress indicators.

 We'll also include a simple script for drag and drop and adding new tasks.

 Let's design the columns with:
   - Each column has a fixed width and a header with a background color and the category name.
   - Tasks are in a scrollable area (if many tasks).

 We'll use the following colors for columns:
   - To Do: gray (bg-gray-200)
   - In Progress: blue (bg-blue-200)
   - Done: green (bg-green-200)

 For the task card, we'll have:
   - A header with the title and a progress bar (if progress is not 0 or 100, show a bar)
   - The progress bar will be a small one at the top right of the card.

 We'll also add a button to add a new task in each column? Or a global add button? Let's put an "Add Task" button in the top right of the board.

 We'll also add a form for adding a new task that appears when the button is clicked.

 We'll use modals for adding tasks? Or a form that is always visible? Since it's a small board, we can have a form that is fixed at the top.

 Alternatively, we can have a form that is always visible at the top of the board.

 Let's design:

   

     
Kanban Board
     Add Task
   

   Then a form that is hidden by default, and when the button is clicked, it becomes visible.

 We'll use Tailwind classes for styling.

 Let's code accordingly.

 Note: We are to focus on the design and functionality. We'll use the provided template as inspiration for the layout and animations, but we are creating a Kanban board.

 We'll also add some animations for the drag and drop.

 We'll use the following JavaScript for drag and drop:

   function allowDrop(ev) {
     ev.preventDefault();
   }

   function drag(ev) {
     ev.dataTransfer.setData("text", ev.target.id);
   }

   function drop(ev) {
     ev.preventDefault();
     const data = ev.dataTransfer.getData("text");
     const draggedElement = document.getElementById(data);
     ev.target.appendChild(draggedElement);
   }

 We'll also update the category of the task when it is dropped in a new column.

 We'll store the category in the task element? Or we can use data attributes.

 We'll add a data-category attribute to each task.

 Then when we drop, we can update the task's category.

 We'll also update the progress bar color to match the column.

 Let's code accordingly.

 We'll also add a form to add new tasks. The form will have:
   - Title (text input)
   - Category (select: todo, inprogress, done)
   - Progress (number input, 0-100)

 We'll generate a unique id for each task.

 We'll use a simple array to store tasks and then render them.

 We'll use the following structure for the task card:

   

     

        
Task Title
        

          

        
     
   

 We'll update the progress bar width and color when the task is added or updated.

 We'll also update the progress bar color to match the column.

 We'll use the following color for progress bars:
   - todo: gray
   - inprogress: blue
   - done: green

 We'll also add a delete button on each task? Not required, but we can add.

 Let's keep it simple.

 We'll create the HTML structure and then the JavaScript to handle:

   - Adding a task
   - Drag and drop
   - Updating the progress bar

 We'll use Tailwind classes for styling.

 Let's code accordingly.
