Building the page

We will have two main sections on the main page: the product list and the cart.

To create the layout, we could use basic HTML tags, such as table and div, but this is quite laborious for our task. Instead, let's introduce a framework named Bootstrap (https://getbootstrap.com/).

This open source framework is widely used and very mature. It allows us to build a responsive website based on a grid, with a lot of components such as notifications, menus, badges, and tooltips. Bootstrap needs a CSS and some JavaScript libraries to work.

For now, we just need to add the Bootstrap CSS by adding the link in the HTML header, as follows:

<head>
    <title>@title</title>
      <!-- Bootstrap CSS -->
    <link rel="stylesheet" 
    href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0
    /css/bootstrap.min.css" integrity="sha384-        
    Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW
    /dAiS6JXm" crossorigin="anonymous">

Mikaël Valot is Principal Software Engineer at IHS Markit in London, UK. He is the lead developer of a strategic market risk solution for banking regulation. He has over 15 years of experience in the financial industry of the UK, Switzerland, and France. He has a Diplôme d'Ingénieur in Computing (equivalent to an M.Sc.) from Telecom Nancy, France. After years of working with Java, he started developing professionally with Scala in 2010, and never looked back. He was a speaker at Scala Exchange 2015. When he is not coding in Scala, Mikaël likes to dabble with Haskell, the Robotic Operating System, and deep learning. He strongly believes that functional programming with strong typing is the best way to write safe and scalable programs.

This book teaches you how to build and contribute to Scala programs, recognizing common patterns and techniques used with the language. You'll learn how to write concise, functional code with Scala. After an introduction to core concepts, syntax, and writing example applications with scalac, you'll learn about the Scala Collections API and how the language handles type safety via static types out-of-the-box. You'll then learn about advanced functional programming patterns, and how you can write your own Domain Specific Languages (DSLs). By the end of the book, you'll be equipped with the skills you need to successfully build smart, efficient applications in Scala that can be compiled to the JVM.
