Domains: HTML

Don't worry if these examples use tags you have not learned.

You will learn about them in the next chapters.

HTML Documents

All HTML documents must start with a document type declaration: <!DOCTYPE html>.

The HTML document itself begins with <html> and ends with </html>.

The visible part of the HTML document is between <body> and </body>.

<!DOCTYPE html>

<h1>My First Heading</h1>
<p>My first paragraph.</p>


HTML Headings

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

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

<h1>This is heading 1</h1>
<h2>This is heading 2</h2>
<h3>This is heading 3</h3>

HTML Paragraphs

HTML paragraphs are defined with the <p> tag:

<p>This is a paragraph.</p>
<p>This is another paragraph.</p>

HTML Links

HTML links are defined with the <a> tag:

<a href="">This is a link</a>

The link's destination is specified in the href attribute. ;

Attributes are used to provide additional information about HTML elements.

You will learn more about attributes in a later chapter.

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

<img src="w3schools.jpg" alt="" width="104" height="142">
