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: “If I had an animation project, I would name it Animation_FightScenes_002. If I created a world-building scene, I would name it WorldBuilding_TropicalIsland_023.”

A block of code is set as follows:

foreach (AudioSource source in audioSources)
        {
            source.clip = audioClip;
            source.spatialBlend = 1f;
        }
Play();

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

[default]
exten => s,1,Dial(Zap/1|30)
exten => s,2,Voicemail(u100)
exten => s,102,Voicemail(b100)
exten => i,1,Voicemail(s0)

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: “Click Add Layer, and create a new layer called Floor in User Layer 8.”
