This is my way of creating a digital with just HTML, SCSS, and vanilla JavaScripts. Let me tell you how.

Procedures

  • Create a folder with any name you want.
  • Go into the folder you have created and enter your favorite text editor.
  • Create an HTML file with the name index.html. Here's the syntax.
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Digital Clock</title>
    <link rel="stylesheet" href="style.css" />
  </head>
  <body onload="initClock()">
    <!-- greeting -->
    <h1 id="greeting"></h1>

    <!--Clock Start-->
    <div class="datetime">
      <div class="date">
        <span id="dayname">Day</span>,
        <span id="month">Month</span>
        <span id="daynum">00</span>,
        <span id="year">Year</span>
      </div>
      <div class="time">
        <span id="hour">00</span>: <span id="minutes">00</span>:
        <span id="seconds">00</span>
        <span id="period">AM</span>
      </div>
    </div>
    <!-- Clock end -->

    <!-- footer -->
    <footer class="footer">
      <p>
        2021 | Made with <span style="color: #e25555">&#9829;</span> by
        <a href="https://www.instagram.com/kbrnugroho/" target="_blank"> Naufal Akbar Nugroho</a>
      </p>
    </footer>
    <!-- footer end -->

    <script src="script.js"></script>
  </body>
</html>
  • And then, let's we create the styles.css. Here's the syntax.
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

body {
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
  background: #10101e;
  font-family: "Segoe UI", sans-serif;
  flex-direction: column;
}

#greeting {
  color: #ffff;
  margin-bottom: 10px;
}

.datetime {
  color: #ffff;
  background: #10101e;
  width: 340px;
  padding: 15px, 10px;
  border: 3px solid #2e94e3;
  border-radius: 5px;
  -webkit-box-reflect: below 1px linear-gradient(tranparent, rgba(255, 255, 255, 0.1));
  transition: 0.5s;
  transition-property: background, box-shadow;
  cursor: pointer;
}

.datetime:hover {
  background: #2e94e3;
  box-shadow: 0 0 30px #2e94e3;
}

.date {
  font-size: 20px;
  font-weight: 500;
  text-align: center;
  letter-spacing: 3px;
}

.time {
  font-size: 60px;
  display: flex;
  justify-content: center;
  align-items: center;
}

.time span:not(:last-child) {
  position: relative;
  margin: 0 6px;
  font-weight: 500;
  text-align: center;
  letter-spacing: 3px;
}

.time span:last-child {
  background: #2e94e3;
  font-size: 30px;
  font-weight: 500;
  text-transform: uppercase;
  margin-top: 10px;
  padding: 0 5px;
  border-radius: 3px;
}

.footer {
  position: absolute;
  top: 42em;
  left: 0px;
  right: 0px;
  text-align: center;
  color: white;
  cursor: default;
}

.footer p {
  padding: 10px;
  margin-top: -10px;
}

.footer a {
  text-decoration: none;
  color: white;
}

.footer a:hover {
  color: #dedede;
}
  • Last thing, we create the script.js file. Here's the syntax.
// clock start
function updateClock() {
  var now = new Date();
  var dname = now.getDay();
  mo = now.getMonth();
  dnum = now.getDate();
  yr = now.getFullYear();
  hou = now.getHours();
  min = now.getMinutes();
  sec = now.getSeconds();
  pe = "AM";
  var midday;
  var name = "Nopal";

  midday = hou >= 12 ? "PM" : "AM";

  if (hou < 12) {
    var greeting = "Good Morning, " + name + "!";
  } else if (hou >= 12 && hou <= 18) {
    var greeting = "Good Afternoon, " + name + "!";
  } else if (hou >= 18 && hou <= 21) {
    var greeting = "Good Evening, " + name + "!";
  } else if (hou >= 21 && hou <= 24) {
    var greeting = "Good Night, " + name + "!";
  }

  document.getElementById("greeting").innerHTML = greeting;

  Number.prototype.pad = function (digits) {
    for (var n = this.toString(); n.length < digits; n = 0 + n);
    return n;
  };

  var months = ["January", "February", "March", "April", "May", "june", "July", "August", "September", "October", "November", "December"];
  var week = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
  var ids = ["dayname", "month", "daynum", "year", "hour", "minutes", "seconds", "period"];
  var values = [week[dname], months[mo], dnum.pad(2), yr, hou.pad(2), min.pad(2), sec.pad(2), pe];
  for (var i = 0; i < ids.length; i++) document.getElementById(ids[i]).firstChild.nodeValue = values[i];
}

function initClock() {
  updateClock();
  window.setInterval("updateClock()", 1);
}
  • And so we have our Digital Clock using HTML, SCSS, and Vanilla JavaScript!
