Start from A
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: <!DOCTYPE html>.
<html> and ends with </html>. The visible part of the HTML document is between <body> and </body>.
<!DOCTYPE html> <html> <body>
Formula
< h1 > My First Heading </h1 >
< p > My first paragraph.</p ></body> </html>
Formula
The <!DOCTYPE > Declaration<!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).
<!DOCTYPE> declaration is not case sensitive.
<!DOCTYPE> declaration for HTML5 is: <!DOCTYPE html>
<h1> to <h6> tags. <h1> defines the most important heading. <h6> defines the least important heading:
Formula
< h1 > This is heading 1 </h1 >
< h2 > This is heading 2 </h2 >
< h3 > This is heading 3 </h3 ><p> tag:
Formula
< p > This is a paragraph.</p >
< p > This is another paragraph.</p ><a> tag:
<a href="https://www.w3schools.com">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.
<img> tag. The source file ( src ), alternative text ( alt ), width, and height 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?"
Click CTRL + U in an HTML page, or right-click on the page and select "View Page Source". This will open a new tab containing the HTML source code of the page.
Right-click on an element (or a blank area), and choose "Inspect" 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.
