It took me quite a while to figure this out. I wanted to share here in case anyone else couldn't get the code to work. Also, if anyone can help me freeze the countdown at 0 0 0 0 when the date & time are reached, I would greatly appreciate it!
Be aware that I adjusted the naming, spacing, emojis and made the countdown timer continue to show even after the date & time are reached. To remove this, you just need to adjust the following:
instead of
countdown.style.display = "block";
use
countdown.style.display = "none";
This works in 2 parts:
1. You add a Markdown code block inside your page with the following code:
(taken from CubeSquared)
<div class="container">
<h1 id="headline">Countdown to our Wedding</h1>
<div id="countdown">
<ul>
<li><span id="days"></span>days</li>
<li><span id="hours"></span>Hours</li>
<li><span id="minutes"></span>Minutes</li>
<li><span id="seconds"></span>Seconds</li>
</ul>
</div>
<div class="message">
<div id="content">
<span class="emoji">🎊</span>
<span class="emoji">💕</span>
<span class="emoji">🥂</span>
</div>
</div>
</div>
<script>
(function () {
const second = 1000,
minute = second * 60,
hour = minute * 60,
day = hour * 24;
let birthday = "Sep 10, 2025 14:00:00",
countDown = new Date(birthday).getTime(),
x = setInterval(function() {
let now = new Date().getTime(),
distance = countDown - now;
document.getElementById("days").innerText = Math.floor(distance / (day)),
document.getElementById("hours").innerText = Math.floor((distance % (day)) / (hour)),
document.getElementById("minutes").innerText = Math.floor((distance % (hour)) / (minute)),
document.getElementById("seconds").innerText = Math.floor((distance % (minute)) / second);
//do something later when date is reached
if (distance < 0) {
let headline = document.getElementById("headline"),
countdown = document.getElementById("countdown"),
content = document.getElementById("content");
headline.innerText = "It's our wedding day!";
countdown.style.display = "block";
content.style.display = "block";
clearInterval(x);
}
//seconds
}, 0)
}());
</script>
2. You add the styling code to the Custom CSS area under website tools (also from CubeSquared):
/* countdown styling*/
#block-235dba99820ac497257a {
* {
box-sizing: border-box;
margin: 0;
padding: 0;
}
.sqs-slide-wrapper[data-slide-type="lock-screen"] .sqs-slide {
height: 100%;
margin: 0;
}
.sqs-slide-wrapper[data-slide-type="lock-screen"] .sqs-slide {
align-items: center;
display: flex;
font-family: -apple-system,
BlinkMacSystemFont,
"Segoe UI",
Roboto,
Oxygen-Sans,
Ubuntu,
Cantarell,
"Helvetica Neue",

}
.container {

margin: 0 auto;
text-align: center;
}
h1 {
font-weight: normal;
letter-spacing: .125rem;
text-transform: uppercase;
margin-bottom: 3rem;
}
li {
display: inline-block;
font-size: 1.5em;
list-style-type: none;
padding: 1em;
text-transform: uppercase;
}
li span {
display: block;
font-size: 4.5rem;
margin-bottom: 2.5rem;
}
.message {
font-size: 4rem;
margin-top: 1.5rem;
}
#content {
display: none;
padding: 1rem;
}
.emoji {
padding: 0 .25rem;
}
@media all and (max-width: 768px) {
h1 {
font-size: 1.5rem;
}
li {
font-size: 1.125rem;
padding: .75rem;
}
li span {
font-size: 3.375rem;
}
}
}
