Is it possible to fix a table-header at the point where it "hits" the top of the page?

Question

I've set up a table in a basic html5 syntax. Now I want the table header to keep its position as it reaches the top of the site while scrolling down. What is the easiest way to handle this problem. I'm not that experienced in javascript and jQuery.

Answer 1

You may have to look into this:

window.onscroll = function() {
  myFunction()
};

var header = document.getElementById("myHeader");
var sticky = header.offsetTop;

function myFunction() {
  if (window.pageYOffset > sticky) {
    header.classList.add("sticky");
  } else {
    header.classList.remove("sticky");
  }
}

body {
  margin: 0;
  font-family: Arial, Helvetica, sans-serif;
}

.top-container {
  background-color: #f1f1f1;
  padding: 30px;
  text-align: center;
}

.header {
  padding: 10px 16px;
  background: #555;
  color: #f1f1f1;
}

.content {
  padding: 16px;
}

.sticky {
  position: fixed;
  top: 0;
  width: 100%;
}

.sticky+.content {
  padding-top: 102px;
}

<div class="header" id="myHeader">
  <h2>Header of the page</h2>
</div>

<div class="content">
  <h3>On Scroll Sticky Header</h3>
  <p>The header will stick to the top when you reach its scroll position.</p>
  <p>Scroll back up to remove the sticky effect.</p>
