title: Use Wordpress Filter to modify value of wp_head output?
body: <p>I have just started with Worpdress, and see what when creating a custom theme there is an annoying margin at the top of the page, and that is caused by the content output by the wp_head function. Since I need to learn how to use filters, I thought I would use a filter to remove the css for the html and body tags from the wp_head functions. </p>
  
  <p>The question is, how do I do that? Inside the function I use for a filter, how I am able to access the values for the css written out for the html tag in the wp_head function? Have searched by have found no good explanation for this. </p>
