Food is a basic necessity – it’s the fuel that keeps us going every day. But it also offers us many other benefits. Certain types of food, such as oily fish, vegetables, fruits and other plant foods, stand out in the nutritional crowd because they have special properties that make them unique in terms of how beneficial they can be to our health. And it is because of their health-enhancing qualities that we sometimes refer to these as ‘superfoods’. The nutrients contained within these foods can assist with many of the body’s natural functions – such as digestion, boosting the immune system, strengthening bones and even helping to protect against cancer.
We’ve all heard the word ‘antioxidant’. But what exactly are dietary antioxidants, and what do they do? In short, ‘antioxidant’ is the term used to describe the group of vitamins, minerals and certain phytochemicals, found in foods, that help to protect the body from the damaging effects of oxygen free radicals. These are unstable molecules that are created naturally by the body and that can also be produced by toxins (like tobacco), pollution and radiation from sunlight and radioactive materials.
These toxins can be ‘carcinogenic’ – meaning they can alter or damage cells in the body which can lead to the development of cancer. Antioxidants are able to ‘mop-up’ free radicals or prevent them from forming, and it is thought that they could thereby help to prevent cell damage.
Web UI design is sometimes mistakenly thought of as how the website looks. Interface design isn’t just about colors and shapes, but rather about presenting the user with the right tools to accomplish their goals.
Web user interfaces are much more than buttons, menus, and forms for users to fill out. It is the connection between the user and the experience, the first impression, and a lasting impression that either makes a website feel like an old friend or a forgettable passerby. Great web UI design must strike a perfect balance between captivating aesthetics and effortless interactivity. Like an invisible hand, a web interface should guide users through the experience at the speed of thought.
In this book, we’ll share a wide breadth of expert commentary, theories, best practices, and real-life examples of brilliant web interfaces. We’ll discuss basic concepts like the general principles of visual design and UI design. For more experienced readers, we’ve included how to research and apply web UI patterns, how to create and test visual hierarchies, and how to apply best practices towards individual elements of web interfaces. Our hope is that it helps you see the visual, structural, and experiential details of web interfaces.
