Removing inline CSS styles using Jquery?

You can remove that inline style with this:

$(document).ready(function(){
  $('.myheader').each(function(idx,el){
    el.style.marginTop='';
  });
});

jQuery.noConflict()

Many JavaScript libraries use $ as a function or variable name, just as jQuery does. In jQuery's case, $ is just an alias for jQuery, so all functionality is available without using $. If we need to use another JavaScript library alongside jQuery, we can return control of $ back to the other library with a call to $.noConflict():

<script type="text/javascript" src="other_lib.js"></script>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
  $.noConflict();
  // Code that uses other library's $ can follow here.
</script>
