<meta>

This is one of those tags that uses only one part. The proper syntax is...

<meta http-equiv="Content-type" content="text/html; charset=utf-8"> <meta name="description" content="Blogger is a free blog publishing tool from Google for easily sharing your thoughts with the world. Blogger makes it simple to post text, photos and video onto your personal or team blog."> <meta name="keywords" content="blogger, blogspot, blog, blogger.com, blogspot.com, free blog, personal blog, weblog, create blog, new blog">
(Stolen from the page source of the new post page.)

Meta controls most of the information that is sent to the browser. It usually includes what kind of format the page is in, what character set it uses (or what language is used.), and a few other things. Since it has SOOO many possible atributes, I will be going through them slowly.
The main use of a meta tag is so that search engines can find information about a site. When you use google, the google bots (what goes out and finds the <meta> tag and reads from it.

I'll go more into this tag later.
