In the beginning, create a new HTML, CSS & JavaScript file..
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Clock using JavaScript</title>
<link rel="stylesheet" href="style.css" />
<script src="app.js" defer></script>
</head>
<body></body>
</html>
Then, put a h2 with three span with the ID hours, minutes and seconds..
<h2>
<span id="hours">00</span> : <span id="minutes">00</span> :
<span id="seconds">00</span>
</h2>
Now, it will look like this..
Add some basic styling with a background..
body {
padding: 0;
margin: 0;
box-sizing: border-box;
min-height: 100vh;
background-image: url("https://images.unsplash.com/photo-1605364441002-c1dbf7d9c7f1?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&q=100");
background-repeat: no-repeat;
background-position: center 40%;
display: flex;
align-items: center;
justify-content: center;
}
h2 {
font-size: 7rem;
color: white;
}
It will look like this..
After that, create the main function which will get the time and put it into the spans
// Define the hours, minutes & seconds elements.
const hoursEl = document.getElementById("hours");
const minutesEl = document.getElementById("minutes");
const secondsEl = document.getElementById("seconds");
function main() {
const totalSeconds = new Date().getTime() / 1000;
const hours = Math.floor(totalSeconds / 3600) % 24;
const minutes = Math.floor(totalSeconds / 60) % 60;
const seconds = Math.floor(totalSeconds) % 60;
hoursEl.innerText = formatTime(hours);
minutesEl.innerText = formatTime(minutes);
secondsEl.innerText = formatTime(seconds);
}
// Format the time by adding 0 before the time if it's less than 10..
function formatTime(time) {
return time < 10 ? `0${time}` : time;
}
// Initial call.
main();
// Call the function every second.
setInterval(main, 1000);
and yeah, now it’s working..
