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: “Then, Bob writes JavaScript source code (random.js) that is responsible for web application behavior.”
A block of code is set as follows:
function getRandomInt(max) {
return Math.floor(Math.random() * max) + 1;
}
function generateRandom() {
let max = document.getElementById('max').value;
alert(getRandomInt(max));
}
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
<body> <button disabled>Generate number</button> <label for="max">up to</label> <input type="number" id="max" name="rand_max" value="10" /> <div id="result"></div> </body> </html>
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 on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Select System info from the Administration panel.”
