Every website is three layers deep. HTML gives a page structure and meaning, CSS decides how it looks on every screen it lands on, and PHP is what makes it respond to the person visiting. Learn all three and you can build a site on your own, start to finish.
One portfolio website runs through all three courses: marked up in semantic HTML with accessible forms and validated against W3C standards, styled and made responsive with the box model, Flexbox, and CSS Grid, then made dynamic with PHP templates and a working contact form.
By the end of this Specialization, you will be able to:
1. Structure accessible pages with semantic HTML, forms, tables, and media.
2. Apply selectors, the cascade, and the box model to style pages.
3. Build layouts with Flexbox and CSS Grid and make them responsive.
4. Write PHP using variables, control flow, arrays, functions, and templates.
5. Process form submissions with server-side validation and sanitization.
6. Handle email, redirects, and sessions on a dynamic site.
This Specialization suits aspiring web developers, career changers, students building a first portfolio, and designers, marketers, or small business owners who want to build and maintain their own site. It assumes no prior programming experience and needs only a computer, a text editor, and a modern browser.
Enroll now to build your first website and turn it into a working dynamic site.
Projet d'apprentissage appliqué
Across the Specialization, you complete hands-on projects that build one portfolio website from a blank file to a running site. You structure it with semantic HTML, wire navigation with relative paths, and add images, lists, data tables, embedded media, and an accessible contact form, validating the result against W3C standards. You then style it, controlling spacing with the box model, setting typography and web fonts, building layouts with Flexbox and CSS Grid, and making every page responsive with media queries.
Finally, you install PHP, generate content with arrays and loops, extract reusable header and footer templates, and make the contact form work with server-side validation, sanitization, email delivery, and sessions. The finished site is a concrete artifact you can publish and add to a professional portfolio.
