So I've been trying to create a simple before/after slider for my website and after a while i managed to do some copy pasting that eventually gave me this code.
The code works fine when simply put in a text document and launched as a html file but when added into a code block on squarespace the before picture streches with the slider rather than being cropped by it.
I'm really not good at coding and any help will be appreciated.
<div id="page">
<div class="wrapper">
<div class="before">
<img class="content-image" src="https://static1.squarespace.com/static/5ef72eea964b6e3a6fece508/t/5f11f277df199179a75be322/1595011709533/after.jpg" draggable="false"/> </div>
<div class="after">
<img class="content-image" src="https://static1.squarespace.com/static/5ef72eea964b6e3a6fece508/t/5f11f26a402f1548b9366293/1595011696334/before.jpg
" draggable="false"/>
</div>
<div class="scroller">
<svg class="scroller__thumb" xmlns="http://www.w3.org/2000/svg" width="100" height="100" viewBox="0 0 100 100"><polygon points="0 50 37 68 37 32 0 50" style="fill:#fff"/><polygon points="100 50 64 32 64 68 100 50" style="fill:#fff"/></svg>
</div>
</div>
</div>
<script>// I hope this over-commenting helps. Let's do this!
// Let's use the 'active' variable to let us know when we're using it
let active = false;
// First we'll have to set up our event listeners
// We want to watch for clicks on our scroller
document.querySelector('.scroller').addEventListener('mousedown',function(){
active = true;
// Add our scrolling class so the scroller has full opacity while active
document.querySelector('.scroller').classList.add('scrolling');
});
// We also want to watch the body for changes to the state,
// like moving around and releasing the click
// so let's set up our event listeners
document.body.addEventListener('mouseup',function(){
active = false;
document.querySelector('.scroller').classList.remove('scrolling');
});
document.body.addEventListener('mouseleave',function(){
active = false;
document.querySelector('.scroller').classList.remove('scrolling');
});
// Let's figure out where their mouse is at
document.body.addEventListener('mousemove',function(e){
if (!active) return;
// Their mouse is here...
let x = e.pageX;
// but we want it relative to our wrapper
x -= document.querySelector('.wrapper').getBoundingClientRect().left;
// Okay let's change our state
scrollIt(x);
});
// Let's use this function
function scrollIt(x){
let transform = Math.max(0,(Math.min(x,document.querySelector('.wrapper').offsetWidth)));
document.querySelector('.after').style.width = transform+"px";
document.querySelector('.scroller').style.left = transform-25+"px";
}
// Let's set our opening state based off the width,
// we want to show a bit of both images so the user can see what's going on
scrollIt(450);
// And finally let's repeat the process for touch events
// first our middle scroller...
document.querySelector('.scroller').addEventListener('touchstart',function(){
active = true;
document.querySelector('.scroller').classList.add('scrolling');

document.body.addEventListener('touchend',function(){
active = false;
document.querySelector('.scroller').classList.remove('scrolling');
