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>
<html>
<body>

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

</body>
</html>

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:

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

HTML paragraphs are defined with the <p> tag:

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

HTML links are defined with the <a> tag:

<a href="https://bhavithacherukuri.blogspot.com/">click me</a>

The link’s destination is specified in the html attribute.

Attributes are used to provide additional information about HTML elements.

HTML images are defined with the <img> tag.

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

<img src="dog.jpg" alt="dogs.com" width="104" height="142">
