Thank you

Answer 3

You're welcome!

When you're done learning HTML, I'd recommend that you learn Javascript so you can add in some client-side functionality. CSS to provide styling. Then I'd learn a server-side language (NodeJS or PHP for example) to deal with server-side processing, as well as SQL/NoSQL so you can use client/server-side languages to interact with a database to store information (such as user accounts). Once you're comfortable with all of that, I'd learn jQuery, ReactJS, AngularJS and Bootstrap. There are many frameworks/libraries out there, but those are used a lot and will make your life as a developer much easier.

Best of luck to you!
