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: “By adding BindableProperty, you can configure your custom ContentView or pass data to it, as we did with the Text property.”

A block of code is set as follows:

public string Text {
    get { return (string)GetValue(TextProperty); }
    set { SetValue(TextProperty, value); }
}
public static readonly BindableProperty TextProperty = BindableProperty.Create("Text", typeof(string), typeof(EditableCard));

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

<Grid ColumnDefinitions="*,*" RowDefinitions="*,*">
    <Label Grid.Row="1" Grid.Column="1"/>
</Grid>
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 example, words in menus or dialog boxes appear in the text like this. Here is an example: “Type any text into the input field and press the Send button.”
