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: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

IFS(
       WEEKDAY([DATE)=1, "Weekly Holiday",
       WEEKDAY([DATE])=7, "Half Working Day",
       AND(WEEKDAY([DATE])1,  WEEKDAY([DATE])7),  "Working 
       Day"
)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

IFS(
       WEEKDAY([DATE)=1, "Weekly Holiday",
       WEEKDAY([DATE])=7, “Half Working Day”,
       AND(WEEKDAY([DATE])1,  WEEKDAY([DATE])7),  "Working 
       Day"
)

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 on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Select System info from the Administration panel.”
