Ouch! My head hurts!

Any HTML programming tutorial will tell you that HTML webpages are composed of two areas: a head section and a body section. The head section usually comes first, although you don’t normally see it when you view a webpage in your web browser. The head section includes a number of important subdivisions: the title tag — which contains the information which is displayed at the top of the window when your web browser is open; metatags — well-known to search engine optimization fans. The head section may also contain codes and scripts for cascading style sheets and JavaScript sections. As with the human body, if the head section is malfunctioning it will affect the performance of the rest of the body.
