You should follow and learn in this exact order because jumping between sections could make it harder to understand some things. After you get efficient with HTML, CSS, JavaScript, you will be able to build more complex and interactive websites.


HTML (HyperText Markup Language) is the backbone for any web page. Web browsers can read HTML files and render them into visible or audible web pages.
