Can I make it so clicking a nav item takes me about 20 pixels higher than the linked ID, accounting for the nav bar?

When I click on any link in the nav bar, the relevant Headings are always covered up by the nav bar. Is there any way to adjust the offset of where it takes you?

Thank you in advance (:

There's a CSS solution that involves a negative margin so it's not ideal on Firefox. The best solution that I've encountered is this one:

function offsetAnchor() {
      if (location.hash.length !== 0) {
        window.scrollTo(window.scrollX, window.scrollY - 20);
      }
    }
    // Captures click events of all a elements with href starting with #
    $('a[href*=#]:not([href=#])').click(function() {
      // Click events are captured before hash changes. Timeout
      // causes offsetAnchor to be called after the page jump.
      window.setTimeout(function() {
        offsetAnchor();
      }, 0);
    });
    // Set the offset when entering page with hash present in the url
    window.setTimeout(offsetAnchor, 0);

Where it says window.scrollY - 20, you would adjust the 20 to the number of pixels you want to offset it.

Thanks

This code looks pretty intimidating! No way I could have come up with this on my own.
