How do I stick the header?

I've tried position:fixed but the content merged with the banner.

You'll need to apply some padding to the top of the body rule. The padding value should be the height of your header.

To stick to the top left of the screen:

display: sticky; position: absolute; top: 0; left: 0;

Yep your correct. Should be

position: sticky; top: 0; left: 0;

Also to note, the student's method is another valid approach to this, without the need to change the position value to sticky. The value fixed will keep the element fixed to the the top in combination with the position properties:

.element {
  position: fixed;
  top: 0;

  /*  You can optionally add these */
  left: 0;
  right: 0;

  /*  If you don't use left and right */
  width: 100%;
}

/*  To solve the student's problem of the element colliding with other elements on the page */
body {
  padding-top: ;/* add value of the element's (header) height */
}
