loading screen ♡

<!--
FULLSCREEN LOADING SCREEN SETUP
──────────────────────────────
♡ the HTML can be placed anywhere inside the <body>
♡ the <script> should be placed before </body>
♡ the CSS should go in your main stylesheet or inside a <style> tag
-->

<!-- =========================
     LOADER HTML
     =========================
change the src to the link of your image
(works as gifs or png, you can choose)
-->

<div id="loader-wrapper">
    <img src="/your-image.gif" alt="loading...">
</div>

<!-- =========================
     LOADER JAVASCRIPT
     =========================
this script controls when the loader appears and disappears.

BEHAVIOR:
♡ waits for the loader image to be ready
♡ shows the loader as soon as the image is loaded
♡ keeps it visible until the entire page finishes loading
♡ after page load:
  - waits 1.5 seconds
  - fades the loader out over 1 second

IMPORTANT:
♡ you can change the value from 1500 to:
- 1000 (disappears faster)
- 3000 (stays longer)
or just mess with the numbers until you're happy :3
-->

<script>
const loader = document.getElementById('loader-wrapper');
const img = loader.querySelector('img');
const body = document.body;

function showLoader() {
    loader.classList.add('active');
    body.classList.add('loading');
}

if (img.complete) {
    showLoader();
} else {
    img.addEventListener('load', showLoader);
}

window.addEventListener('load', function() {
    setTimeout(() => {
        loader.classList.remove('active');
        setTimeout(() => {
            body.classList.remove('loading');
        }, 1000);
    }, 1500);
});
</script>

<!-- =========================
     LOADER CSS
     =========================
this CSS makes the loader:
♡ fixed to the viewport
♡ full width and height
♡ sit above all content
♡ fade in and out smoothly
-->

<style>
#loader-wrapper {
    position: fixed;
    top: 0;
    left: 0;
    width: 100vw;
    height: 100vh;
    background: #000;
    z-index: 9999999;
    opacity: 0;
    transition: opacity 1s ease-in-out;
    pointer-events: none;
    display: block;
}

#loader-wrapper.active {
    opacity: 1;
    pointer-events: auto;
}

#loader-wrapper img {
    width: 100%;
    height: 100%;
    object-fit: cover;
}
</style>
