Answer 1

First calculate the height of first element i.e( 80px including border and paddings ) in your case.

Give 80px top to the second element.

Third element will have a top of 160px and so on.

All elements will have position:sticky

Try this,

body{color:#fff; font-family:arial; font-weight:bold; font-size:40px; height:1000px}
.main-container{ max-width:600px; margin:0 auto; border:solid 10px green; padding:10px; margin-top:40px;}
.main-container *{padding:10px;background:#aaa; border:dashed 5px #000;}
.main-container * + *{margin-top:20px;}
.main-header{
  height:50px; background:#aaa; border-color:red;
}
.main-content{
  min-height:1000px;
}

.main-header{position:sticky; top:0px;}
div.main-header{top:80px }
.main-footer{position:sticky; top:160px }

<main class="main-container">
  <header class="main-header">HEADER</header>
  <div class="main-header">MAIN CONTENT</div>
  <footer class="main-footer">FOOTER</footer>
</main>
