Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The information from the frontend goes to receive_json, which in turn receives the 'text in capital letters' action by executing the self.send_uppercase(data) function."

A block of code is set as follows:

* {

    font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;

    box-sizing: border-box;

}

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "At the moment, the Edit and Delete buttons are for decoration; later, we will give them their functionality."
