In this chapter we will show some basic HTML examples. Don't worry if we use tags you have not learned about yet.
All HTML documents must start with a document type declaration: . The HTML document itself begins with and ends with . The visible part of the HTML document is between and .
<!DOCTYPE html> <html> <head> <title>Page Title</title> </head> <body> <h1>My First Heading</h1> <p>My first paragraph.</p> </body> </html>
The 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 declaration is not case sensitive. The 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:
<h1>This is heading 1</h1> <h2>This is heading 2</h2> <h3>This is heading 3</h3>
HTML paragraphs are defined with the tag:
<p>This is a paragraph.</p> <p>This is another paragraph.</p>
HTML links are defined with the <a> tag:
<a href="https://www.w3schools.com">This is a link</a>
The link's destination is specified in the attribute. Attributes are used to provide additional information about HTML elements. You will learn more about attributes in a later chapter.
HTML images are defined with the tag. The source file (), alternative text (), , and are provided as attributes:
<img src="w3schools.jpg" alt="W3Schools.com" width="104" height="142">
Have you ever seen a Web page and wondered "Hey! How did they do that?"
Right-click in an HTML page and select "View Page Source" (in Chrome) or "View Source" (in Edge), or similar in other browsers. This will open a window containing the HTML source code of the page.
Right-click on an element (or a blank area), and choose "Inspect" or "Inspect Element" to see what elements are made up of (you will see both the HTML and the CSS). You can also edit the HTML or CSS on-the-fly in the Elements or Styles panel that opens.
