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: "We'll start by installing the relevant plugins required for this demo: we'll need the postcss-nested, autocomplete, and postcss-scss plugins."

A block of code is set as follows:

gulp.task('rename', ['styles'], function () {
  return gulp.src('dest/example.css')
    .pipe(postcss([ cssnano ]))
    .pipe(rename('example.min.css'))
    .pipe(gulp.dest("dest/"));
});

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

var sourcemaps = require('gulp-sourcemaps');
var rename = require('gulp-rename');
var cssnano = require('cssnano')

Any command-line input or output is written as follows:

npm install -–save-dev cssnano
npm install -–save-dev gulp-rename

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: "When we view the page and select the Images tab, after a short delay we should see six new images."

Note

Warnings or important notes appear in a box like this.
