Current Ratio Calculator Card using Tailwind CSS & JavaScript

Last Updated : 08 Mar, 2024

A Current Ratio Calculator is a web-based tool that allows users to calculate the current ratio of a company. The current ratio is a financial metric that measures a company's ability to pay its short-term liabilities with its short-term assets. It is calculated by dividing the company's current assets by its current liabilities. The calculator is styled using Tailwind CSS, a utility-first CSS framework, which ensures a responsive and visually appealing design.

Approach to create Current Ratio Calculator Card:

Begin with a basic HTML structure, including the <!DOCTYPE html> declaration, <html>, <head>, and <body> tags. Import Tailwind CSS for styling.
Create a container div with Tailwind CSS classes for styling. Inside the container, include elements for the calculator title, input fields for current assets and liabilities, a button for calculating the current ratio, and a div for displaying the result.
Use JavaScript to handle the calculation logic. Add an event listener to the calculate button. When the button is clicked, the script retrieves the values from the input fields, validates them, calculates the current ratio, and displays the result in the result div.
Use Tailwind CSS classes to style the calculator container, input fields, button, and result div. Customize the colors, fonts, and layout to create an appealing visual design for the calculator.
Use JavaScript to check if the input values are valid numbers and if the current liabilities are not zero. If any of the values are not valid, display an error message in the result div.
