Overview

This project is a web designing aiming to create a simple clock ..The clock includes a hour needle, minute needle, second needle and day & date . Utilizing CSS for styling and HTML & JS for basic structure and detailing. The project adds a decent look to your website . It also have a light/dark mode.

Step 1: Creating a folder name clock and make a index.html file :

Now copy the HTML Code in your index.html file.

				
					<!DOCTYPE html>
<html lang="en">




<head>
  <meta charset="UTF-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <link rel="stylesheet" href="style.css" />
  <title>Theme Clock</title>
</head>




<body>
  <button class="toggle">Dark mode</button>
  <div class="clock-container">
    <div class="clock">
      <div class="needle hour"></div>
      <div class="needle minute"></div>
      <div class="needle second"></div>
      <div class="center-point"></div>
    </div>
    <div class="time"></div>
    <div class="date"></div>
  </div>
  <script src="script.js"></script>
</body>




</html>

Step 2: Now create a file name style.css:

Now link the style.css file to index.html using "<link rel="stylesheet" href="style.css" />"

Now copy CSS code in style.css.

				
					@import url("https://fonts.googleapis.com/css?family=Heebo:300&display=swap");

* {
  box-sizing: border-box;
}

:root {
  --primary-color: #000;
  --secondary-color: #fff;
}

html {
  transition: all 0.5s ease-in;
}

html.dark {
  --primary-color: #fff;
  --secondary-color: #333;
}

html.dark {
  background-color: #111;
  color: var(--primary-color);
}

body {
  font-family: "Heebo", sans-serif;
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
  overflow: hidden;
  margin: 0;
}

.toggle {
  background-color: var(--primary-color);
  color: var(--secondary-color);
  border: 0;
  border-radius: 4px;
  padding: 8px 12px;
  position: absolute;
  top: 10px;
  right: 10px;
  cursor: pointer;
}

.toggle:focus {
  outline: none;
}

.clock-container {
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: space-between;
}

.clock {
  position: relative;
  width: 200px;
  height: 200px;
}

.needle {
  background-color: var(--primary-color);
  position: absolute;
  top: 50%;
  left: 50%;
  height: 65px;
  width: 3px;
  transform-origin: bottom center;
  transition: all 0.5s ease-in;
}

.needle.hour {
  transform: translate(-50%, -100%) rotate(0deg);
}

.needle.minute {
  transform: translate(-50%, -100%) rotate(0deg);
  height: 100px;
}

.needle.second {
  background-color: #e74c3c;
  transform: translate(-50%, -100%) rotate(0deg);
  height: 100px;
}

.center-point {
  background-color: #e74c3c;
  width: 10px;
  height: 10px;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  border-radius: 50%;
}

.center-point::after {
  content: "";
  background-color: var(--primary-color);
  width: 5px;
  height: 5px;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  border-radius: 50%;
}

.time {
  font-size: 60px;
}

.date {
  color: #aaa;
  font-size: 14px;
  letter-spacing: 0.3px;
  text-transform: uppercase;
}

.date .circle {
  background-color: var(--primary-color);
  color: var(--secondary-color);
  border-radius: 50%;
  height: 18px;
  width: 18px;
  display: inline-flex;
  align-items: center;
  justify-content: center;
  font-size: 12px;
  line-height: 18px;
  transition: all 0.5s ease-in;
}

Step3 :Create a anothe file name script.js:

Now link the style.cssfile to index.html using “<script src=”script.js”></script>”
Note: JS file will be added in end of the body element.

Now copy JS Code in script.js file

				
					const hourElement = document.querySelector(".hour");
const minuteElement = document.querySelector(".minute");
const secondElement = document.querySelector(".second");
const timeElement = document.querySelector(".time");
const dateElement = document.querySelector(".date");
const toggle = document.querySelector(".toggle");

const days = [
  "Sunday",
  "Monday",
  "Tuesday",
  "Wednesday",
  "Thursday",
  "Friday",
  "Saturday",
];
const months = [
  "Jan",
  "Feb",
  "Mar",
  "Apr",
  "May",
  "Jun",
  "Jul",
  "Aug",
  "Sep",
  "Oct",
  "Nov",
  "Dec",
];

toggle.addEventListener("click", (e) => {
  const html = document.querySelector("html");
  if (html.classList.contains("dark")) {
    html.classList.remove("dark");
    e.target.innerHTML = "Dark mode";
  } else {
    html.classList.add("dark");
    e.target.innerHTML = "Light mode";
  }
});

const scale = (num, in_min, in_max, out_min, out_max) => {
  return ((num - in_min) * (out_max - out_min)) / (in_max - in_min) + out_min;
};

const setTime = () => {
  const time = new Date();
  const date = time.getDate();
  const month = time.getMonth();
  const day = time.getDay();
  const hours = time.getHours();
  const hoursForClock = hours >= 13 ? hours % 12 : hours;
  const minutes = time.getMinutes();
  const seconds = time.getSeconds();
  const ampm = hours >= 12 ? "PM" : "AM";

  hourElement.style.transform = `translate(-50%, -100%) rotate(${scale(
    hoursForClock,
    0,
    11,
    0,
    360
  )}deg)`;
  minuteElement.style.transform = `translate(-50%, -100%) rotate(${scale(
    minutes,
    0,
    59,
    0,
    360
  )}deg)`;
  secondElement.style.transform = `translate(-50%, -100%) rotate(${scale(
    seconds,
    0,
    59,
    0,
    360
  )}deg)`;

  timeElement.innerHTML = `${hoursForClock}:${minutes < 10 ? `0${minutes}` : minutes
    } ${ampm}`;
  dateElement.innerHTML = `${days[day]}, ${months[month]} <span class="circle">${date}</span>`;
};

setTime();

setInterval(setTime, 1000);

conclusion:

This code sets up a simple clock. It utilizes CSS for styling , HTML & JS for basic structure and detailing like a hour needle, minute needle, second needle and day & date . The code is structured and easily customizable for further development.
