Creating a Customizable Digital Clock with HTML, CSS, and JavaScript
In this tutorial, we'll create a customizable digital clock using HTML, CSS, and JavaScript. The clock will display the current time in real-time and can be easily customized to fit your needs.
Prerequisites
To follow this tutorial, you should have a basic understanding of HTML, CSS, and JavaScript.
Step 1: Setting Up the HTML
We'll start by setting up the HTML for the digital clock. Create a new file named index.html and paste the following code:
<!DOCTYPE html
<html>
? <head>
??? <title>Digital Clock</title>
??? <link rel="stylesheet" href="style.css">
? </head>
? <body>
??? <div class="clock">
????? <div class="time">
??????? <span class="hours"></span>
??????? <span class="separator">:</span>
??????? <span class="minutes"></span>
??????? <span class="separator">:</span>
??????? <span class="seconds"></span>
????? </div>
??? </div>
??? <script src="script.js"></script>
? </body>
</html>>
In this code, we've created a basic HTML structure with a div element with a class of clock that will contain our digital clock. Inside the div element, we've created another div element with a class of time that will display the current time. The time is displayed using five span elements with classes of hours, minutes, seconds, and separator.
We've also added a link to a CSS file named style.css and a script tag that links to a JavaScript file named script.js.
Step 2: Styling the Digital Clock
Next, we'll style the digital clock using CSS. Create a new file named style.css and paste the following code:
.clock
? display: flex;
? justify-content: center;
? align-items: center;
? height: 100vh;
? background-color: #f7fafc;
}
.time {
? display: flex;
? font-size: 10rem;
? font-weight: bold;
? color: #1a202c;
}
.separator {
? margin: 0 0.5rem;
}
.hours, .minutes, .seconds {
??? display: inline-block;
??? width: 8.5rem;
??? text-align: center;
??? background-color: #fff;
??? color: #333;
??? border-radius: 0.5rem;
??? margin: 0 0.25rem;
??? padding: 0.25rem;
??? box-shadow: 0 0.2rem 0.4rem rgba(0, 0, 0, 0.2);
}
In this code, we've styled the div element with a class of clock to center the clock on the page and set the background color. We've also styled the div element with a class of time to display the time using a large font size and a bold font weight. Finally, we've styled the span element with a class of separator to add a margin between the time elements.
Step 3: Displaying the Current Time
Now that we've set up the HTML and CSS, we can use JavaScript to display the current time in real-time.

Create a new file named script.js and paste the following code:
function updateTime()
? const date = new Date();
? const hours = date.getHours().toString().padStart(2, '0');
? const minutes = date.getMinutes().toString().padStart(2, '0');
? const seconds = date.getSeconds().toString().padStart(2, '0');
? document.querySelector('.hours').textContent = hours;
? document.querySelector('.minutes').textContent = minutes;
? document.querySelector('.seconds').textContent = seconds;
}
setInterval(updateTime, 1000);{
In this code, we've created a function named updateTime that gets the current date and time using the Date object. We've then used the padStart method to add leading zeros to the hours, minutes, and seconds to ensure that they are always displayed using two digits.
Finally, we've used querySelector to select the span elements with the classes of hours, minutes, and seconds and update their text content with the current time. We've also used setInterval to call the updateTime function every second to ensure that the clock is always displaying the correct time.
Step 4: Customizing the Digital Clock
Now that we've created a basic digital clock, we can customize it to fit our needs. Here are some examples of changes you can make:
You can also modify the functionality of the digital clock by modifyingthe JavaScript code. For example, you can change the time format from 24-hour to 12-hour by modifying the hours variable in the updateTime function.
// JavaScript Documen
function updateClock() {
??? const now = new Date();
??? // Get the current hours, minutes, and seconds
??? let hours = now.getHours();
??? const minutes = now.getMinutes().toString().padStart(2, '0');
??? const seconds = now.getSeconds().toString().padStart(2, '0');
??? // Convert hours to 12-hour format
??? const amOrPm = hours >= 12 ? 'PM' : 'AM';
??? hours = hours % 12 || 12;
??? // Update the time string
??? const timeString = `${hours}:${minutes}:${seconds} ${amOrPm}`;
??? // Update the HTML elements
??? document.querySelector('.hours').textContent = hours.toString().padStart(2, '0');
??? document.querySelector('.minutes').textContent = minutes;
??? document.querySelector('.seconds').textContent = seconds;
??? document.querySelector('.am-pm').textContent = amOrPm;
}
setInterval(updateClock, 1000);
Conclusion
In this tutorial, we've created a customizable digital clock using HTML, CSS, and JavaScript. We've learned how to display the current time in real-time and how to customize the appearance and functionality of the clock.
I hope you found this tutorial helpful and that you enjoy customizing your own digital clock!
