HTML Documents

HTML is the standard markup language for creating webpages.

The <!Doctype> Declaration

The <!DOCTYPE> declaration represents the document type, and helps browsers to display web pages correctly.

It must only appear once, at the top of the page (before any HTML tags).

The <!DOCTYPE> declaration is not case sensitive.

The <!DOCTYPE> declaration for HTML5 is: <!DOCTYPE html>

HTML headings are defined with the <h1> to <<h6> tags.

<h1> defines the most important heading. <h6> defines the least important heading.

HTML Paragraphs

HTML paragraphs are defined with the <p> tag.

HTML Images

HTML images are defined with the <img> tag.

The source file (src), alternative text (alt), width, and height are provided as attributes.
