html - Fixed page header overlaps in-page anchors

Question

If I have a non-scrolling header in an HTML page, fixed to the top, having a defined height:

Is there a way to use the URL anchor (the #fragment part) to have the browser scroll to a certain point in the page, but still respect the height of the fixed element without the help of JavaScript?

WRONG (but the common behavior):         CORRECT:
+---------------------------------+      +---------------------------------+
| BAR///////////////////// header |      | //////////////////////// header |
+---------------------------------+      +---------------------------------+
| Here is the rest of the Text    |      | BAR                             |
| ...                             |      |                                 |
| ...                             |      | Here is the rest of the Text    |
| ...                             |      | ...                             |
+---------------------------------+      +---------------------------------+

Answer 1

If you can’t or don’t want to set a new class, add a fixed-height ::before pseudo-element to the :target pseudo-class in CSS:

:target::before {
  content: "";
  display: block;
  height: 60px; /* fixed header height*/
  margin: -60px 0 0; /* negative fixed header height */
}

Or scroll the page relative to :target with jQuery:

var offset = $(':target').offset();
var scrollto = offset.top - 60; // minus fixed header height
$('html, body').animate({scrollTop:scrollto}, 0);
