Semantic elements communicate the purpose of different sections of a webpage. Examples include header, nav, main, section, article, aside, and footer.

Using semantic HTML can improve maintainability, accessibility, and the overall structure of webpages.

HTML5 provides several elements for collecting information from users.

You can learn how to create:

4. Images and Multimedia

Students learn how to add images, audio, video, links, and other media elements to webpages while maintaining a well-organized structure.

CSS selectors allow developers to target HTML elements and apply specific styling rules.

Common selectors include element selectors, class selectors, ID selectors, attribute selectors, pseudo-classes, and pseudo-elements.

6. CSS Box Model

The CSS box model is one of the most important concepts for understanding webpage layouts. It includes content, padding, border, and margin.

• Personal portfolio website

• Responsive business website

• Landing page

• Blog interface

• E-commerce product page

• Interactive JavaScript project

For every project, explain the technologies used, your role, important features, responsive behavior, and the development challenges you solved.
