This new edition of the book covers Tailwind 3.0, which changes the way Tailwind generates its CSS. Tailwind 3.0 has a large number of new features powered by the new system, including the ability to use arbitrary values with most Tailwind class patterns, and a new syntax for combining color and opacity in a single class. This book also covers the new standalone command-line tools for Tailwind. With CSS, you can do amazing things to the basic text and images on your website, and with just a little bit of client-side code to add and remove CSS classes, you can do exponentially more. In the latest edition of this book, you'll learn how to use Tailwind 3.0 and the new way it generates CSS. You'll code your way through Tailwind's newest features, including the ability to use arbitrary values with most Tailwind class patterns and a new syntax for combining color and opacity in a single class. You'll even dive into the new standalone command-line tools for Tailwind. The Tailwind setup is extremely explicit and makes it possible to understand the display just by looking at the HTML markup. Start by designing the typographic details of the individual elements, then placing and manipulating those elements in "the box" using a flexbox or grid design. Finally, move those elements around the page with helpful small animations and transitions. With Tailwind, it's easy to prototype, iterate, and customize your display, use prefixes to specify behavior, change defaults, add new behavior, and integrate with legacy CSS. Use Tailwind to make extraordinary web designs without extraordinary effort. What You Need: This book is about Tailwind 3.0. You should have a basic knowledge of CSS and HTML.

4 zettabytes (4 billion terabytes) of data generated in 2013, 44 zettabytes predicted for 2020 and 185 zettabytes for 2025. These figures are staggering and perfectly illustrate this new era of data deluge. Data has become a major economic and social challenge. The speed of processing of these data is the weakest link in a computer system: the storage system. It is therefore crucial to optimize this operation. During the last decade, storage systems have experienced a major revolution: the advent of flash memory. Flash Memory Integration: Performance and Energy Issues contributes to a better understanding of these revolutions. The authors offer us an insight into the integration of flash memory in computer systems, their behavior in performance and in power consumption compared to traditional storage systems. The book also presents, in their entirety, various methods for measuring the performance and energy consumption of storage systems for embedded as well as desktop/server computer systems. We are invited on a journey to the memories of the future.
