Document Type

Everything is HTML is described through elements. This includes the larger structure of the main document.

In this sub-topic, we’ll build the basic structure of a single page, going step-by-step through the standard page elements. It is worthwhile to note that, usually, there is only one set of each of these elements per page, beginning with a <!DOCTYPE> declaration. We can even compare these elements to your own very structure.

<!DOCTYPE>

The document type element is the first element in an HTML document, and should be placed on the first line in a document. This element tells the browser’s processor what type of HTML document it is.

The <!DOCTYPE> declaration is not an HTML tag; it is an instruction to the web browser about what version of HTML the page is written in.
