دانلود کتاب CSS در عمق، ویرایش دوم

CSS was proposed in 1994 and first implemented (partially) by Internet Explorer 3 in 1996. It was somewhere around that time I discovered the wonderful View Source button and realized all the secrets of a web page were there for me to decipher in plain text. I taught myself HTML and CSS by playing in a text editor and seeing what worked. It was a fun excuse to spend as much time as possible on the internet. In the meantime, I needed to find a real career. I went on to earn a degree in computer science. Little did I know that the two would come crashing together in the 2000s as the concept of “web developer” emerged. I’ve been in tune with CSS since the very beginning. Even when I’m working, it’s play. I’ve worked on the backend and the frontend, yet I’ve always found myself to be the resident CSS expert on every team I’ve been on. It’s often the most neglected part of the web stack. Once you’ve been on a project with clean CSS, you never want to do without it again. After seeing it in action, even seasoned web developers ask, “How do I learn CSS?” There isn’t one concise, straightforward answer to this question. It’s not a matter of learning one or two quick tips. Rather, you need to understand all the disparate parts of the language and how they fit together. Some books make a good beginnerlevel introduction to CSS, but many developers already have a basic understanding. Some books teach a lot of useful tricks but assume the reader has mastery over the language. At the same time, the rate of change in CSS is accelerating. We’ve seen the rise of newer, modern layout methods and effects like blend modes, filters, transformations, transitions, and animations. Even in the last year or two, logical properties, cascade layers, and container queries have dramatically changed the way we write the language. There is a lot to keep up with. Whether you are relatively new to the industry or have been at it a while but need to advance or update your CSS skills, I have written this book to bring you up to speed. Everything in this book is here for one of three reasons:  It’s essential. There are many fundamentals of the language that, sadly, many developers don’t fully understand. These include the cascade, page layout, and positioning. I’ll take a deep look at these, explaining how they work.  It’s new. A lot of new features have emerged in the last few years or are just now emerging. I will cover the latest improvements to CSS and a few things that are just around the corner. This is a forward-thinking book. I will point out backward compatibility issues where relevant, but I am unabashedly optimistic about the future of CSS development, and my goal is to provide you with an understanding of the language that is ready for emerging changes.  It’s not covered in most CSS books. The world of CSS is huge. There are important best practices and common approaches in the modern world of web application development. These are not strictly part of the CSS language but rather part of its culture. And they are vital for modern web development. So, how do you learn CSS? This book is an attempt to answer that question. It is a comprehensive guide intended to teach practical proficiency in the language.
