Today I learned:

Javascript Counter

The results:

00

days

00

hours

00

minutes

00

seconds

The javascript, which counts the time since a certain date:

document.addEventListener("DOMContentLoaded", function(event) { // Month,Day,Year,Hour,Minute,Second upTime('Nov,10,2015,00:00:00'); }); function upTime(countTo) { now = new Date(); countTo = new Date(countTo); difference = (now-countTo); days=Math.floor(difference/(60*60*1000*24)*1); hours=Math.floor((difference%(60*60*1000*24))/(60*60*1000)*1); mins=Math.floor(((difference%(60*60*1000*24))%(60*60*1000))/(60*1000)*1); secs=Math.floor((((difference%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1); document.getElementById('days').firstChild.nodeValue = days; document.getElementById('hours').firstChild.nodeValue = hours; document.getElementById('minutes').firstChild.nodeValue = mins; document.getElementById('seconds').firstChild.nodeValue = secs; clearTimeout(upTime.to); upTime.to=setTimeout(function(){ upTime(countTo); },1000); }

The elements it targets:

id="countup"> class="part"> id="days">00
class="label"> class="timeRefDays">days

class="part"> id="hours">00
class="label"> class="timeRefHours">hours

class="part"> id="minutes">00
class="label"> class="timeRefMinutes">minutes

class="part"> id="seconds">00
class="label"> class="timeRefSeconds">seconds

And the styles to display it:

#countup { margin-left: auto; margin-right: auto; text-align: center; font-family: "Lato",Helvetica,Arial,sans-serif; } #countup p { display: inline-block; padding: 0px; margin: 0; font-size:100px; line-height: 100px; text-align: center; } #countup #seconds, #countup .timeRefSeconds { color:red; } #countup .part { display: inline-block; text-align: center; width: 23%; } #countup .label p{ font-size: 30px; } @media only screen and (max-width: 960px) { #countup p { font-size: 60px; line-height: 60px; } #countup .label p{ font-size: 20px; } } @media only screen and (max-width: 500px) { #countup p { font-size: 45px; line-height: 45px; } #countup .label p{ font-size: 16px; } }
