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: “Here, null is passed because there are no properties.”
A block of code is set as follows:
<div className=”title”> <span>Oh no!</span> </div>
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
React.createElement( 'span', null, title ? title : 'Something important' );
Any command-line input or output is written as follows:
$ mkdir css $ cd css
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: “Select System info from the Administration panel.”
