Je crée un site Web de portfolio et je souhaite que mon texte fixe change de couleur dans certaines parties, comment puis-je faire cela ? Je ne peux pas poster mon code car il est trop gros et trop long, mais ce serait bien si vous pouviez donner un exemple de code, voici à quoi il ressemble (https://olaolu.dev), vous pouvez voir comment les boutons et les noms sont dans Changer les couleurs lors du défilement :)
P. Veuillez utiliser js pour le faire, merci !
J'ai essayé de chercher des informations mais je n'ai rien trouvé :(

<h1>Design</h1>
<p>
I'm probably not the typical designer positioned behind an Illustrator artboard adjusting pixels, but I design. Immersed in stylesheets tweaking font sizes and contemplating layouts is where you'll find me (~_^). I'm committed to creating fluent user experiences while staying fashionable.
</p>
</div>
<div class="what-doing" id="i2">
<h1>Engineering</h1>
<p>
In building JavaScript applications, I'm equipped with just the right tools, and can absolutely function independently of them to deliver fast, resilient solutions optimized for scale — performance and scalabilty are priorities on my radar

Je pense que ce dont vous avez besoin, c'est d'un observateur d'intersection. Intersection Observer vous permet de « voir » les cibles et de réagir lorsqu'elles deviennent visibles.
J'ai créé un petit exemple pour démontrer cela. Nous regardons 第二节. Lorsqu'il est visible, nous changeons la couleur en violet. Lorsqu'il n'est pas visible, nous le remettons en noir.
const title = document.querySelector('.topbar__title');
const sectionOne = document.querySelector('.section--one');
const sectionTwo = document.querySelector('.section--two');
const observer = new IntersectionObserver((entry, observer) => {
entry[0].isIntersecting > 0 ?
title.style.color = sectionTwo.getAttribute('data-color') :
title.style.color = sectionOne.getAttribute('data-color')
});
observer.observe(sectionTwo);
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
.topbar {
position: fixed;
top: 0;
left: 0;
padding: 1rem;
width: 100%;
background-color: white;
}
.section {
height: 150vh;
width: 100%;
display: flex;
align-items: center;
justify-content: center;
}
.section--one {
background-color: white;
}
.section--two {
background-color: rgb(255 0 0 / 5%);
}
Section One
Section Two
Bien sûr, vous pouvez observer plusieurs sections ou modifier une classe au lieu de la styliser avec JS. Ceci n'est qu'un exemple simple...
MDN a de bonnes informations sur les Intersection Observers
