Vertical scrolling by sections (like a slide)

I'm trying to create a page with 3 sections that change to the next one by giving scroll like a slideshow where each section is a frame. Like this site here: link

This is the .HTML:

<section id="apresentacao">

  <h2>Section One</h2>

</section>

<section id="catergorias">

  <h2>Section Two</h2>

</section>

<section id="estoque">

  <h2>Section Three</h2>

</section>

No .js:

var sectionOne = $('section')[0].offsetTop;
var sectionTwo = $('section')[1].offsetTop;
var sectionThree = $('section')[2].offsetTop;

$(document).on("scroll", function() {
  if (window.pageYOffset <= sectionTwo){
    $("html, body").animate({scrollTop: sectionTwo},1000);
}
  else if (window.pageYOffset <= sectionThree) {
    $("html, body").animate({scrollTop: sectionThree},1000);
}
  else if (window.pageYOffset >= sectionThree) {
    $("html, body").animate({scrollTop: sectionTwo},1000);
}
})

In this case, it only recognizes the first scroll and then hangs in the second section. Does anyone know how I can solve it? Thanks

Dude as I had commented from to do something very similar only with CSS and HTML. Even using transitions etc.

I used radio buttons and transitions to make the effect. In addition it is well resposnivo because it is all in Flex practically.

See the result!

    box-sizing: border-box;
    margin: 0;
    padding: 0;

    position: fixed;
    display: flex;

}
.links label {
