Conventions

To help you get the most from the text and keep track of what's happening, we've used a number of conventions throughout the book.

For instance:

Important

These boxes hold important, not to be forgotten information, which is directly relevant to the surrounding text.

While the background style is used for asides to the current discussion.

As for styles in the text:

• When we introduce them, we highlight important words

• We show keyboard strokes like this: Ctrl-K

• We show filenames and code within the text like so: <element>

Text on user interfaces and URLs are shown as: Menu

We present code in two different ways:

In our code examples, the code foreground style shows new, important,   pertinent code while code background shows code that is less important in the present    context or has been seen before.
