Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Each row is wrapped in <LI> tags."

A block of code is set as follows:

SELECT node_field_data.title AS node_field_data_title, node_field_data.nid AS nid
FROM 
{node_field_data} node_field_data
WHERE (( (node_field_data.status = '1') AND (node_field_data.type IN  ('open_house')) ))
ORDER BY node_field_data_title DESC
LIMIT 10 OFFSET 0

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "She clicked on the Apply (all displays) button."
