How to create Word, Letter and Digit Counter Card using JavaScript and Tailwind CSS ?

Last Updated : 23 Jul, 2024

The Word Digit and Letter Counter Application allows users to input text and dynamically count the number of words, letters, and digits in the text. Additionally, it provides the "Clear" button to reset the text and clear all counts. The HTML code structures the document, while Tailwind CSS classes handle styling, and JavaScript adds interactivity to the Word, Letter, and Digit Counter applications.

Output Preview: Let us have a look at how the final output will look like.

Approach

Integrate the Tailwind CSS via CDN Link in your HTML code. Use different HTML elements to structure the web page and style them using different Tailwind utilities.
In the <body> tag, Set the background color to gray (bg-gray-100), making the body occupy the full height of the screen (h-screen), and centering its content both horizontally and vertically (flex justify-center items-center).
The <textarea> tag creates an input field for user text input, styled with Tailwind CSS classes for width, height, padding, margin-bottom, border, rounded corners, and focus styles (w-full h-40 px-4 py-2 mb-4 border border-gray-300 rounded-md resize-none focus:outline-none focus:border-blue-500). It also includes a placeholder text for user guidance.
The clearText() function clears the text in the text area when the "Clear" button is clicked. Initial counts are displayed upon page load.
The updateCounts() function is called whenever there's an input event in the text area. This function calculates and updates the word, letter, and digit counts.
The textarea allows users to input text which is then processed to count words, letters, and digits.
