<p> "<strong>Regular Guidelines</strong>" aims at the actual problems encountered by the author during development and the questions consulted by other developers. It summarizes a set of methods for using regular expressions to solve problems, and guides readers through specific examples to dismantle them. Solve and analyze problems. The book is divided into three parts: the first part mainly explains the basic knowledge of regular expressions, covering various functions and structures in common regular expressions; the second part mainly explains more in-depth knowledge about regular expressions, and discusses in detail Coding issues, matching principles, and problem-solving ideas; the third part implements the various knowledge introduced previously into 6 commonly used languages. net, java, javascript, php, python, and ruby. It not only introduces in detail the regular expressions in the language Usage also points out the subtle differences between versions. It can be used as a textbook for specialized study and as a useful reference manual. <br /> "Regular Guide" is suitable for technical personnel who often need to perform text processing (such as log analysis or network operation and maintenance), programmers who are familiar with common development languages, and readers who already have a certain understanding of regular expressions. </p> <p> <span> Translator<br /> </span><br /> Yu Sheng, graduated from the Computer Science Department with a minor in Chinese, is an unorthodox technology enthusiast.

<p class="p" style="background:#FFFFFF;"> HTML5 is increasingly favored by Internet development teams at home and abroad. Abroad, Google is enthusiastically developing the Chrome Web Store, Microsoft has released the "Irish Spring" theme website that supports the development of HTML5 technology, and Nokia has spent huge sums of money to acquire and build the NOKIA MAP business. Domestic Internet giants are also interested in the new web development standards coming from the other side of the ocean, and have begun to test the waters of HTML5 products. </p> <p class="p" style="background:#FFFFFF;"> <span>微博</span> The iPhone platform Web App product has been successfully launched in the first quarter of 2012. Now I would like to share the experience and lessons learned from the development of this project with everyone, and hope to grow together with you in the HTML5 development environment. </p>

div +s css layout introduction<br /> Are you learning CSS layout? Still can’t quite master pure CSS layout? There are usually two situations that hinder your learning: <br /> The first possibility is that you haven't understood the principle of CSS processing pages. Before you consider the overall performance of your page, you should first consider the semantics and structure of the content, <br /> Then add CSS for semantics and structure. This article will tell you how to structure HTML. <br /> Another reason is that you are at a loss for those very familiar presentation layer attributes (such as cellpadding, hspace, align="left", etc.) and don't know what to do. Convert to the corresponding CSS statement. When you solve the first problem and know how to structure your HTML, I will give you a list detailing the original table<br /> What CSS should I use to replace the current attribute? <br /> Structured HTML<br /> When we first learn web page production, we always consider how to design it first, considering the pictures, fonts, colors, and layout plans. Then we use Photoshop<br /> Or draw it in Fireworks and cut it into small pictures. Finally, edit the HTML to restore all the designs to the page. <br /> If you want your HTML page to be laid out with CSS (CSS-friendly), you need to go back and start over. Don't think about "appearance" first, but think about your page first<br /> Semantics and structure of content. <br /> Appearance is not the most important thing. A well-structured HTML page can take on any look, and CSS Zen Garden is a prime example. CSS Zen<br /> Garden helps us finally realize the power of CSS. <br /> HTML isn't just for reading on a computer screen. Your carefully designed images in photoshop may not display on PDAs, mobile phones, and screen readers. but<br /> It is a well-structured HTML page that can be displayed anywhere and on any network device through different definitions of CSS. <br /> Start thinking<br /> The first thing to learn is what "structure" is, which some writers also call "semantics". What this term means is that you need to analyze your pieces of content, and what each piece of content serves Purpose, and then establish the corresponding HTML structure based on these content purposes. <br />

<p class="MsoNormal" style="text-indent:21.0000pt;"> <span>To learn this series of tutorials, you need to have a certain foundation of </span>html<span> and </span><span>css</span><span>, which means that you have made web pages before and can use table layout. If you have just started learning web page production and don’t know what table layout and </span><span>html</span><span> and </span><span>css</span><span> are, I suggest you recharge your batteries first, otherwise You will have a hard time following this tutorial or you will not understand it at all. </span> </p> <p class="MsoNormal"> ​ </p> <p class="MsoNormal" style="text-indent:21.0000pt;"> <span> Due to time constraints, this tutorial only explains some basic knowledge, allowing you to move from the original table layout to the </span>web<span> standard (</span><span>div css</span><span>) layout , will use the </span><span>web</span><span> standard to create common pages, which also achieves the purpose of this tutorial. </span> </p> <p class="MsoNormal"> ​ </p> <p class="MsoNormal" style="text-indent:21.0000pt;"> This tutorial is mostly explained step by step in the form of examples. The key points or difficulties involved in the examples will be explained, and the concepts will be less explained. Because concepts are difficult to explain clearly, or even if you explain them clearly, you may not be able to understand them, and even if you understand them, you may not be able to understand them. So I leave the concept to you to study in depth later. </p> <p class="MsoNormal"> ​ </p> <p class="MsoNormal" style="text-indent:21.0000pt;"> <span>Due to the relationship between chapters, </span>css<span> and </span><span>css hack</span><span> are not separated separately, but are explained interspersed when used. </span><span>html</span><span>Basics and </span><span>css</span><span>Basics only introduce a few important points in the first section. </span> </p> <p class="MsoNormal"> ​ </p>
