< !DOCTYPE html>
< html>
  < head>
    < title>Online Digital Clock with Seconds< /title>
    < link rel="stylesheet" href="style.css">
  < /head>
  < body>
    < div id="clock">< /div>

    < script src="script.js">< /script>
  < /body>
< /html>

Explanation:

The DOCTYPE declaration specifies the HTML version.
The head section includes a title for the page and links to the CSS and JavaScript files.
The body section includes a div element with an ID of "clock" to display the clock, and a script tag to link to the JavaScript file.

#clock {
  font-size: 48px;
  font-weight: bold;
  color: #333;
  text-align: center;
  margin-top: 100px;
}

Explanation:

The #clock selector targets the div element with an ID of "clock".
The font-size property sets the font size of the clock display.
The font-weight property sets the font weight to bold.
The color property sets the text color.
The text-align property centers the clock display.
The margin-top property adds space between the clock display and the top of the page.

Javascript Digital Clock With Seconds Example Code

function updateClock() {
  // Get the current time using the Date() object
  const now = new Date();

  // Format the time using the toLocaleTimeString() method
  const timeString = now.toLocaleTimeString();

  // Update the clock display by setting the innerHTML property of the clock div element
  const clock = document.getElementById('clock');
  clock.innerHTML = timeString;
}

// Use the setInterval() method to call the updateClock() function every second
setInterval(updateClock, 1000);

Explanation:

The updateClock() function gets the current time using the Date() object, formats the time using the toLocaleTimeString() method, and updates the clock display by setting the innerHTML property of the clock div element.
The setInterval() method is used to call the updateClock() function every second, which ensures that the clock display is always up to date.
The function first gets the current time using the Date() object by creating a new Date object and storing it in the now variable.
The time is then formatted using the toLocaleTimeString() method, which returns a string in the user's preferred time format and language.
The formatted time string is then used to update the clock display by setting the innerHTML property of the clock div element, which is selected using its ID using the document.getElementById() method and stored in the clock variable.
Finally, the setInterval() method is called with the updateClock() function and a time interval of 1000 milliseconds (1 second) to ensure that the clock display is updated every second.
