The main focus is on web accessibility and, WCAG 2.1 and 2.2 guidelines: what they are, who they are for, and what can be done from a design point of view to make the lives of the users easier. In reviewing the fundamentals, emphasis will be given on what disabilities could potentially prevent users from getting the information they need and what can be done to help them. This is achieved by breaking down web design and development terms and practices, such as web accessibility, color contrast, typography, how to design specific components like carousels, forms, and so on. Each chapter features design examples presented in a clear and concise manner. Each design element is divided into different components, highlighting exactly what helps with what, showing how a website needs to be designed for the benefit of its people. A11Y Unraveled also reviews the current laws and legislations that govern web accessibility in different parts of the world.What You'll LearnDiscover how people perceive information on the web, and how that might create barriers in communication.Review different disabilities or limitations that prevent users from accessing web information and how to address them.Design an accessible website for specific disabilities through practical examples.Understand how different web design components affect the user.Study current web accessibility legislation, avoiding difficult to understand lingo.Who This Book Is ForMain audience would be digital and web professionals (mainly designers but developers can benefit as well).

The second edition of this book has been fully updated to show how the DevOps way of working has continued to adapt to changing technologies. The ITIL processes which were an integral part of the DevOps world have been merged with the DevOps framework, reflecting the current emphasis on product models rather than viewing project and support models separately. This book starts with the basics of digital transformation before exploring how this works in practice: that is, people, processes and technology, and org structures. It delves into value streams that are the basis for ITIL and DevOps, highlighting the differences between the methods of the past and new methodologies needed to ensure products to meet contemporary expectations. This updated edition includes new chapters that discuss digital transformation for business success, introduce the battle tank framework, leading people in the digital world, managing work in a remote working model, and the product-led transformation model. These new chapters provide the guidance necessary to move beyond DevOps into a holistic digital transformation exercise.The ideas, recommendations, and solutions you'll learn over the course of this book can be applied to develop solutions or create proposals for clients, and to deliver seamless services for DevOps projects.What You Will LearnUnderstand digital transformationLeverage the battle tank framework for digital transformationGain insight into the confluence of DevOps and ITILAdapt ITIL processes in DevOps projectsMove organizations from a project to a product-led model Lead teams in a digital worldManage the work of remote teamsWho This Book Is ForIT consultants and IT professionals who are looking for guidance to strategize, plan and implement digital transformation initiatives; design and redesign ITIL processes to adapt to the digital ways of working; moving organizations to product-led business; and leading people and managing work in the digital age.

Among Java's many attractive features as a programming language, its object-oriented nature is key to creating powerful, reusable code and applications that are easy to maintain and extend. To take advantage of these capabilities, you're going to need not only to master the syntax of the Java language, but also to gain a practical understanding of what objects are all about. Most importantly, you need to know how to structure Java applications from the ground up to make the most of objects. With Beginning Java Objects: From Concepts to Code, you'll master all three.Learning to design objects effectively with Java is the goal of Beginning Java Objects: From Concepts to Code. Plenty of titles dig into the Java language in massive detail, but this one takes the unique approach of stepping back and looking at fundamental object concepts first. Mastery of Java—from understanding the basic language features to building complete industrial-strength Java applications—emerges only after a thorough tour of thinking in objects. Let this book be your guide.
