Dans le monde en constante évolution de la conception Web, la création d’éléments attrayants et interactifs est essentielle pour capter l’attention de votre public. Une façon d’y parvenir consiste à intégrer des animations de chargement captivantes dans votre site Web. Dans cet article, nous vous guiderons tout au long du processus de création d’une animation amusante interactive sur le thème du skateboard en utilisant HTML, CSS et JavaScript.
Avant de vous lancer dans le codage, assurez-vous d’avoir une compréhension de base du HTML, du CSS et du JavaScript. Vous aurez également besoin d’un éditeur de code comme Visual Studio Code et d’un navigateur Web moderne pour voir votre animation en action.
Commençons!
- Configuration de la structure HTML
Commencez par créer un nouveau fichier HTML et configurez la structure de base :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Interactive Skate</title>

2. Création des styles CSS
Maintenant, stylisons notre animation de chargement de skate en utilisant CSS. Créez un nouveau fichier CSS (styles.css) et ajoutez les styles suivants :

Dans ce code CSS, nous avons créé un conteneur de chargement en forme de skateboard avec des roues qui tournent et ajouté un style de base.
3. Ajout de l’interactivité JavaScript
Pour rendre notre animation de chargement interactive, créez un nouveau fichier JavaScript (main.js) et ajoutez le code suivant :
const { to, set } = gsap;document.querySelectorAll('.loading').forEach(loading => {
loading.count = 0
let lines = to(loading, {
keyframes: [{
'--line-top-x': '-100%',
'--line-bottom-x': '-200%',
onComplete() {
set(loading, {
'--line-top-x': '200%',
'--line-bottom-x': '100%',
})
}
}, {
'--line-top-x': '0%',
'--line-bottom-x': '0%'
}],
duration: 1,
repeat: -1
})
const keyboard = document.querySelector('#keyboard')
const arrowUp = keyboard.querySelector('.up')
const arrowLeft = keyboard.querySelector('.left')
const arrowRight = keyboard.querySelector('.right')
const arrowDown = keyboard.querySelector('.down')
const spanHidden = keyboard.querySelector('span')
document.body.onkeyup = e => {
if(e.keyCode == 32 || e.keyCode == 38) {
jump(loading, lines)
arrowUp.classList.add('pressed')
setTimeout(() => arrowUp.classList.remove('pressed'), 400)
}
if(e.keyCode == 40 || e.keyCode == 39 || e.keyCode == 37) {
if(!loading.ouch) {
reset(loading, lines)
}
keyboard.querySelector('.pressed').classList.remove('pressed')
}
if(loading.ouch & (e.keyCode == 32 || e.keyCode == 38)) {
loading.ouch = false
reset(loading, lines)
}
}
document.body.onkeydown = e => {
if(e.keyCode == 39){
fast(loading, lines)
arrowRight.classList.add('pressed')
}
if(e.keyCode == 40){
down(loading, lines)
arrowDown.classList.add('pressed')
}
if(e.keyCode == 37) {
slow(loading, lines)
arrowLeft.classList.add('pressed')
}
if(e.keyCode == 67) {
fall(loading, lines)
spanHidden.classList.add('pressed')
setTimeout(() => spanHidden.classList.remove('pressed'), 400)
}
}
if(('ontouchstart' in window) || (navigator.maxTouchPoints > 0) || (navigator.msMaxTouchPoints > 0)) {
spanHidden.innerHTML = "Please don't click here"
}
arrowUp.addEventListener('click', e => {

}
jump(loading, lines)
})

})
const jump = (loading, lines) => {

}
loading.active = true
loading.count += 1
if(loading.count > 3) {
document.querySelector('#keyboard span').classList.remove('hide')
}
