Questions

Should I learn HTML and CSS before JavaScript?

Most learning paths recommend basic HTML and CSS first, because JavaScript is often used to change web pages built with them.

Are the certificates really free?

Each course card states the certificate status: free means the provider issues a certificate or badge at no cost, paid means the learning is free but the certificate costs extra, and none means no certificate is offered. Always confirm on the provider's page before you enrol, as policies change.

Where do I enrol?

Every course links straight to the provider's own page. We do not host the courses or take payment; you sign up with the provider directly.
