Center horizontally and vertically a div in a section and make each section fill the whole page when scrolling

Question

I am trying to code a page where each section fills the whole page. And I am also trying to center vertically and horizontally the divs in each section. I don't know if it's possible, if you guys can enlighten me it would be great. I also would like to know if it's possible that, when I scroll it automatically goes to the next section. I don't know if it's clear enough to understand.

Here's the CSS :

.presta .container {
  width: 100%;
  position: relative;
}

.presta .h1 {
  font-size: 80px;
  font-weight: bold;
}

.presta card {
  padding: 30px;
  margin: 0 auto;
}

.logoPresta:hover {
  transition: transform 0.3s ease-in;
  transform: translateY(-10px);
}

.prestaShow {
  text-align: center;
}

.wrapper {
  min-height: 100%;
}

<div class="navbar ">
  <div class="container flex">
    <div class="logo" data-aos="fade-right">
      <a href="index.html"><img src="images/linko_bg_transp.png" alt="" /></a>
    </div>
    <nav data-aos="fade-in">
      <ul>
        <li><a href="index.html">Accueil</a></li>
        <li><a href="pres.html">Présentation</a></li>
        <li><a href="Presta.html">Nos Prestations</a></li>
        <li><a href="form.html">Nous contacter</a></li>
      </ul>
    </nav>
  </div>
</div>

<section class="presta bg-light wrapper">
  <div class="container">
    <div class="text-center">
      <h1>Nos domaines d'expertises</h1>
    </div>
    <div class="grid grid-4">
      <div class="logoPresta card">
        <img src="images/1.jpg" alt="">
      </div>
      <div class="logoPresta card">
        <img src="images/2.jpg" alt="">
      </div>
      <div class="logoPresta card">
        <img src="images/3.jpg" alt="">
      </div>
      <div class="logoPresta card">
        <img src="images/4.jpg" alt="">
      </div>
    </div>
  </div>
</section>

<section class="prestaShow wrapper">
  <div class="container info">
    <div class="text-center">
      <h2>Informatique</h2>
    </div>
    <div class="textePresta card">

    </div>
    <div class="textePresta card">

    </div>
    <div class="textePresta card">
      Déploiement d'infrastructures réseaux
    </div>

  </div>
</section>

Here are the images of the page :

Answer 1

You can resize section to full page height by changing 100% to 100vh

Also, take a look at CSS section to see how to center wrappers' content (expand Code snippet to see differences).

UPD: .snap-wrapper will help you to scroll full sections, take a look at Code snippet on full-screen.

.presta .container {
  width: 100%;
  position: relative;
}

.presta .h1 {
  font-size: 80px;
  font-weight: bold;
}

.presta card {
  padding: 30px;
  margin: 0 auto;
}

.logoPresta:hover {
  transition: transform 0.3s ease-in;
  transform: translateY(-10px);
}

.prestaShow {
  text-align: center;
}

.wrapper {
  /* centering wrapper content */
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  min-height: 100vh;
}

/* use .snap-wrapper to scroll page by full sections */
.snap-wrapper {
  display: flex;
  flex-direction: column;
  flex-wrap: nowrap;
  scroll-snap-type: y mandatory;
  overflow: auto;
  height: 100vh;
}

.snap-wrapper > .wrapper {
  scroll-snap-align: center;
}
