The head section of the webpage includes all the stuff that does not show directly on the resulting page.
The <title> and </title> tags encapsulate the title of your page. The title is what shows in the top of your browser window when the page is loaded.
Right now it should say something like "Basics - Html Tutorial" on top of the window containing this text.
Another thing you will often see in the head section is metatags. Metatags are used for, among other things, to improve the rankings in search engines.
Finally, more and more pages contain codes for cascading style sheets (CSS).
CSS is a rather new technique for optimizing the layout of major websites.
Since these aspects are way out of reach at this stage we will proceed with explaining the body section. _________________ Thanks & regards
