Doctype Declaration: Begins with
<!DOCTYPE html>to specify HTML5. -
Basic Structure:
-
<html>: Root element. -
<head>: Contains meta-information, title, and links to styles/scripts. -
<body>: Contains the content of the webpage.

<p>,<div>,<a>. - Most tags have opening and closing versions (e.g.,

<br>,<img>).
- Tags are used to create elements, e.g.,
-
Attributes: Extra information in tags, e.g.,
<a href="url">. -
Comments: Written as
<!-- comment here -->for code annotations.
Semantic HTML5 Elements
- Definition: Elements that convey meaning about their content.
-
Key Semantic Elements:
-
<header>: Introductory content or navigational links. -
<nav>: Links for navigating the webpage. -
<main>: Dominant content of the document. -
<article>: Independent content, e.g., blog posts. -
<section>: Thematic grouping of content. -
<aside>: Content related tangentially to the main content (e.g., sidebars). -
<footer>: Closing content or information about the content above.
-
-
Benefits:
- Improves accessibility (screen readers can better navigate).
- Enhances Search Engine Optimization (SEO).

- HTML5 documents begin with the
<!DOCTYPE html>declaration. - The basic structure includes:
-
<html>: The root element. -
<head>: Contains meta-information, the title, and links to stylesheets and scripts. -
<body>: Contains the visible content of the webpage.
-
- HTML uses tags (e.g.,
<p>,<h1>,<a>) to create elements.- Tags typically have opening and closing tags, like
<p>This is a paragraph</p>. - Void elements (like
<br>,<img>) are self-closing, for example,<br>.
- Tags typically have opening and closing tags, like
- Attributes provide additional information within tags, such as
<img src="image.jpg">wheresrcis an attribute. - Comments within HTML are written as
<!-- This is a comment -->.
Semantic HTML5 Elements
- Semantic HTML5 elements convey meaning about their content and enhance the web page's structure for both users and search engines.
- Key semantic elements:
-
<header>: Contains introductory content and navigational links. -
<nav>: Links for navigating the webpage. -
<main>: Encloses the main content of the document. -
<article>: Represents independent content, typically found in blogs or news articles. -
<section>: Groups thematically related content. -
<aside>: Contains content related to, but tangential to, the main content (e.g., sidebars). -
<footer>: Closing content or additional information about the content above.
-
- Benefits of using semantic HTML5 elements:
- Improved accessibility (screen readers can better understand the page structure).
- Enhanced search engine optimization (SEO) by clarifying content organization.
Responsive Design With HTML5
- Responsive design ensures that a webpage looks good on all devices (desktops, tablets, mobiles).
- The viewport meta tag (
<meta name="viewport" ...>) is essential for responsive design, using it allows you to control the layout on mobile browsers. - CSS media queries are used alongside HTML5 to adapt styles based on device characteristics (screen size, resolution).
- Fluid layouts use percentages rather than fixed dimensions for elements, which makes the webpage adapt to different screen sizes.
- Responsive images:
- Use the
