JQuery Scroll to Offset from top of browser?

I have the following scroll script, which scrolls round the page fine, works exactly how i want it too.

$(function(){
    $('a[href*=#]').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'')
        && location.hostname == this.hostname) {
            var $target = $(this.hash);
            $target = $target.length && $target || $('[name=' + this.hash.slice(1) +']');
            if ($target.length) {
                var targetOffset = $target.offset().top;
                $('html,body').animate({scrollTop: targetOffset}, 1000);
                return false;
            }
        }
    });
});

However, i need it to ignore the top say 200px as i have a fixed header at the top of the page that the content scrolls behind.

Meaning that when i scroll to top it scrolls the content to behind the fixed header so i cannot see it, so i need it to scroll to just below the header.. so to treat the bottom of the header as the top of the browser i suppose....

Can this be done as it would be very handy?

Many thanks for any help

The Code is fine, you just need to remove the height of your fixed header here, for example if it's 200px. it will work perfectly.

 $('html,body').animate({scrollTop: (targetOffset().top)-200}, 1000);

You can also check this when a button is clicked

$(function() {

$('a[href*=#]:not([href=#])').click(function() {

    // Check height of the header and padding
    var header_height = $('.header').outerHeight();

Remove it from your offset

$('html,body').animate({scrollTop: (targetOffset().top) - header_height }, 1000);

Would something like this work?

var targetOffset = $target.offset().top - 200;

Or grab the height of the header element for the extra offset.

var targetOffset = $target.offset().top - $("element").outerHeight(true);

You could use something like this if condition on ur code to do that

//check if the absolute position is below header
if ($('#IdOfTheScrollElement').position().top >= 200 ){
//scroll
}
else {
//do nothing
}
