Bootstrap #id href Link Covered by Nav Bar [Fixed]

< h1 id="output" style="padding-top:40px; margin-top:-40px;">

this does not create extra space in content & href to #output now jumps down to this anchor without the top nav bar (default in twitter bootstrap) covering the title up.  no change needed for the href="#output" tag at top.
