Question

The _____________ declaration must be the very first thing in your html document. It is not an html tag, it is an instruction to the web browser about what version of HTML the page is written in.

Answer 1

<!DOCTYPE>

Step-by-step explanation:

The <!DOCTYPE> declaration must be the very first thing in your HTML document. It is not an HTML tag, but rather an instruction to the web browser about what version of HTML the page is written in. The <!DOCTYPE> declaration is used to specify the Document Type Definition (DTD) that the web browser should use to interpret the document. This is important because different versions of HTML have different rules and syntax, so it is important to specify the correct version of HTML to ensure that the document is rendered correctly in the browser.
