What do Front-End Web Developers do?

Front-End Web Developers create the user-facing side of websites. They work with web designers to create the sublime, interactive experiences that make the web the addictive environment it is today. When you clicked on this website, the Udacity servers sent information to your computer, which turned into the page you're seeing right now. Who wrote that code? A Front-End Web Developer.

Front-End Web Developers construct static pages, like this one, as well as dynamic web apps like Twitter, Facebook and Google Docs.

  • Responsible for the design and development of user facing code.
  • Optimize web applications to maximize speed and scalability.
  • Create fast, easy-to-use applications, and develop prototypes quickly.

What to learn in what order?



HTML is the first of the big three languages you need to learn to make websites—HTML, CSS and JavaScript. HTML isn't a programming language per se. It describes how elements on a website should be laid out and provides browsers with a list of all the other files, like CSS and JavaScript, that websites need. You can think of HTML like the blueprint of a house. It tells you how big the rooms are and what should be inside them. But it doesn't tell you how they should look.


If HTML describes the layout of a house, CSS describes the look of a house. CSS, or Cascading Style Sheets, is responsible for the way websites look. Colors, fonts, and even some animations are all controlled by CSS. Like HTML, CSS isn't a programming language. It's a text document that reads like an interior designer's instructions for making a website look great.


Of the big three web languages, JavaScript is the only one that's considered an actual programming language. JavaScript controls interactions on a website. It's like a handyman that can tear down walls, build new rooms and redecorate your house. For a simple, static website, you won't need to use much JavaScript. But for a dynamic web app you'll need an in-depth understanding of the language.

Web design techniques

Responsive design

Open a website and make your browser smaller. Did the page content change its layout to fit the new screen? That’s responsive design. People expect modern websites to look great on their phones and on their laptops. By diving into responsive design principles, you’ll learn how to make websites that scale and adjust themselves to offer amazing experiences regardless of the device.

Modern design languages

A design language is a set of principles used to organize and unify the design of a product. Google, for example, recently released the specifications for Material Design, a modern design language for responsive websites and mobile apps. Material Design puts a focus on using layers that look and behave as if they were made with colored construction paper. Following a design language will help you create cohesive, intuitive experiences for your users.


Bootstrap is a good example of this. Frameworks make it easy to structure and build websites. They provide custom CSS classes that ensures that your content looks great no matter the device. Frameworks can help you follow industry best practices and modern design principles. Other frameworks, like Foundation, provide the same kind of structure for your websites.

Web apps

JavaScript frameworks/templating

You know how your Facebook page has the exact same layout as all of your friends' pages? That's because of templating engines. Templating engines are key for creating dynamic websites based on data that they pull from back-end servers. Understanding how to use a templating engine is the first step in building a web app.

Examples are:

  • Angular—a framework containing a templating engine
  • Ember—a framework containing a templating engine
  • Handlebars—a templating engine
  • Mustache—a templating engine

Peripheral skills

Source code control

With complex projects, how do you maintain your code? Version control software like Git helps software developers around the world save and maintain their code, even as projects grow to hundreds of developers and dozens of subprojects.

Web performance

Once you’ve made your website, how will you ensure it's fast? By understanding a few simple principles of browser rendering, you'll be able to make sure that you deliver fast, efficient websites to your users.
