Learn to Code
There are tons of different technologies out there, each of which has its own tutorials, documentation, and community (good or bad). ADI has done the hard work of tracking down the best resources, summarizing each technology, and identify critical concepts based on goal so that the only thing standing between you and the implementation of your idea is a little bit of learning and hard work.
DevFest is ADI's annual week-long workshop series and hackathon. At DevFest 2016, we showcased the DevFest Tracks, featuring 6 original, self-paced, open-source tutorials in a variety of topics such as web development, iOS development, and data science. The DevFest Tracks are the perfect place to start learning new skills! Read more about the educational methodology and design behind the DevFest curriculum here.
Over the course of multiple years of holding student-run workshops, ADI has developed a large number of resources itself, on a wide variety of topics. See resources written by ADI members highlighed with a gear ().

Extensive reference by the organization behind Firefox. If you need any property of CSS explained to you very clearly or in detail, look here.
Once you've got the hang of CSS, CSS preprocessors allow you to write CSS using more powerful features, such as variables, functions, and “mixins.” After development, these files get compiled into regular CSS that all web browsers can understand. Makes CSS easier.
Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.
The dynamic stylesheet language. LESS extends CSS with dynamic behavior such as variables, mixins, operations and functions.
Stylus is a revolutionary new language, providing an efficient, dynamic, and expressive way to generate CSS. Supporting both an indented syntax and regular CSS style.

If you want to save information when a user leaves your app or coordinate between different users, you need a database of some sort. Here are some good options to get started.
A "relational" database-think about it like an Excel spreadsheet, but stricter, bigger, and more powerful. It might already be installed and it's really easy to set up a database. Note that you'll need to learn the basics of Structured Query Language (SQL) in order to use it.
A "non-relational" database. You put whole "objects" in and can query them in simple or complicated ways. Check out the interactive demo!
Another "relational" database. This one is very popular, and also powerful. You need to know SQL for this. MariaDB is based on MySQL, and was forked after the community worried that Oracle wasn't devoting enough time to the project and was hiding things; they're mostly identical, but MariaDB is the way to go for "MySQL" nowadays.

Java is an object oriented language, and the most widely used language in the world. It is compiled down to Java byte code, and then run on a Java Virtual Machine. Because JVMs have been made for many different platforms, people often say of Java, "Write once, run anywhere.". Java is great language if you want to program for Android or program scalable systems (both big and small companies use Java, but it's not a usual choice for prototyping). We'll probably have a hard time teaching you Java online, so these resources are more advanced.
