Instructions often need some extra explanation so that they make sense, so they are followed with:
What just happened?
This heading explains the working of tasks or instructions that you have just completed.
You will also find some other learning aids in the book, including:
Pop quiz – heading
These are short multiple-choice questions intended to help you test your own understanding.
Have a go hero – heading
These practical challenges give you ideas for experimenting with what you have learned.
You will also find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Once the download is finished, go to the downloaded directory and extract the .zip file into a convenient directory of your choice."
A block of code is set as follows:
<body>
<section>
<div class="jumbotron">
<div class="container">
<h1> ${greeting} </h1>
<p> ${tagline} </p>
</div>
</div>
</section>
</body>
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
<servlet>
<servlet-name>DefaultServlet</servlet-name>
<servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class>
</servlet>
Any command-line input or output is written as follows:
