analog clock
Create a Analog Clock using Html Css and Javascript
So lets start
open notepad and paste html code
<!DOCTYPE html>
<html>
<head>
<title>Analog Clock</title>
<script type="text/javascript" src="script.js"></script>
<link type="text/css" rel="stylesheet" href="style.css">
</head>
<body>
<div class="analog-clock">
<svg width="140" height="140">
<circle id="clock-face" cx="70" cy="70" r="65" />
<line id="h-hand" x1="70" y1="70" x2="70" y2="38" />
<line id="m-hand" x1="70" y1="70" x2="70" y2="20" />
<line id="s-hand" x1="70" y1="70" x2="70" y2="12" />
<line id="s-tail" x1="70" y1="70" x2="70" y2="56" />
<text x="62" y="18">12</text>
<text x="126" y="76">3</text>
<text x="66" y="130">6</text>
<text x="7" y="76">9</text>

<div class="time-text">
<span id="hr">00</span>
<span>:</span>
<span id="min">00</span>
<span>:</span>
<span id="sec">00</span>
<span id="suffix">--</span>
</div>
</div>
</body>
</html>
save this code as clock.html
Javascript code
function clock(){
//calculate angle
var d, h, m, s;
d = new Date;
h = 30 * ((d.getHours() % 12) + d.getMinutes() / 60);
m = 6 * d.getMinutes();
s = 6 * d.getSeconds();
//move hands
setAttr('h-hand', h);
setAttr('m-hand', m);
setAttr('s-hand', s);
setAttr('s-tail', s+180);
//display time
h = d.getHours();
m = d.getMinutes();
s = d.getSeconds();
if(h >= 12){
setText('suffix', 'PM');
}else{
setText('suffix', 'AM');
}
if(h != 12){
h %= 12;
}
setText('sec', s);
setText('min', m);
setText('hr', h);
//call every second
setTimeout(clock, 1000);
};
function setAttr(id,val){
var v = 'rotate(' + val + ', 70, 70)';
document.getElementById(id).setAttribute('transform', v);
};
function setText(id,val){
if(val < 10){
val = '0' + val;
}
document.getElementById(id).innerHTML = val;
};
window.onload=clock;
and save this code as script.js
css code
