What is DOCTYPE?
DOCTYPE (Document Type Declaration) is the first line of code in an HTML document. It tells the web browser or other web agents that this is an HTML document and which version of HTML is being used. The DOCTYPE declaration is essential for ensuring that the web page is displayed correctly and consistently across different browsers.
Example of DOCTYPE:
<!DOCTYPE html>
This is the standard DOCTYPE declaration for HTML5 documents. For more information on DOCTYPE declarations, visit the Mozilla Developer Network documentation: https://developer.mozilla.org/en-US/docs/Web/HTML/Quirks_Mode_and_Standards_Mode
The Head Section
The head section, denoted by the <head>
tag, contains metadata about the HTML document. It provides information about the document's title, character encoding, links to external stylesheets or scripts, and other metadata. The head section is not displayed in the browser window but plays a crucial role in how the document is interpreted and displayed.
Example of the Head Section:
<head>
<title>HTML & Web Development Fundamentals</title>
<meta charset="UTF-8">
<meta name="description" content="A course on HTML and web development fundamentals">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
In this example, we define the document's title, character encoding, description, and viewport settings.
The Body Section
The body section, denoted by the <body>
tag, contains the content of the HTML document. It is the section where you will place your text, images, links, forms, tables, and other multimedia elements. The body section makes up the bulk of the HTML document and is responsible for displaying the content in the browser window.
Example of the Body Section:
<body>
<h1>Welcome to HTML & Web Development Fundamentals</h1>
<p>Learn the basics of HTML and web development in this comprehensive course.</p>
</body>
In this example, we define a simple heading and paragraph of text in the body section.
Meta Tags
Meta tags provide additional metadata about the HTML document. They are typically placed in the head section and provide information about the document's author, keywords, description, and other attributes. Meta tags are essential for search engine optimization (SEO) and can affect how your web page is indexed and ranked.
Common Meta Tags:
meta charset
: specifies the character encoding of the documentmeta name="description"
: provides a brief description of the documentmeta name="viewport"
: controls the zooming and scaling of the document on mobile devicesmeta name="author"
: specifies the author of the documentmeta name="keywords"
: provides a list of keywords associated with the document
