Approach to create Online Voting System Card

Begin with a basic HTML structure, including the <!DOCTYPE html> declaration, <html>, <head>, and <body> tags. Import external resources like Tailwind CSS for styling and Chart.js for creating the pie chart.
Create a container div with Tailwind CSS classes for styling. Inside the container, include a dropdown menu for selecting a color option.
Add buttons for voting, clearing votes, and displaying a pie chart. Use event listeners to trigger the voting, clearing, and chart display functions.
Use JavaScript to handle the voting process, storing votes in local storage, and displaying the pie chart. Define functions to update the vote count, clear votes, and display the chart.
Display the voting result and the list of votes in a div with an id of “result” and “votes” respectively. Use the innerHTML property to update the content of the divs.
