<p style="color:#454545;font-family:&quot;font-size:16px;background-color:#FFFFFF;"> I have been watching AJAX videos these days. After watching the videos, I found that AJAX is not that simple. Some knowledge points are a bit difficult to understand, and many of them are unfamiliar concepts. Therefore, I wanted to write a blog to briefly understand what I know about AJAX. A further understanding, and then continue watching the video, and completing the examples will be much better. Okay, without further ado, let’s look at the content. <br /> AJAX refers to "Asynchronous JavaScript And XML" (Asynchronous JavaScript And XML). AJAX is a programming model popularized by Google in 2005. It is a web development technology for creating interactive web applications. Web application interactions such as Flickr, Backpack and Google have made a qualitative leap in this regard. The term comes from describing the transition from web-based applications to data-based applications. In data-based applications, the data required by the user, such as contact lists, can be obtained from a server independent of the actual web page, and can be dynamically written into the web page, coloring the slow web application experience and making it look like a desktop application. . AJAX is not a new programming language, but a new way of using existing standards. With AJAX, you can create better, faster, and more user-friendly Web applications. AJAX is based on JavaScript and HTTP requests. <br /> The core of AJAX is the JavaScript object XmlHttpRequest. This object was first introduced in Internet Explorer 5 and is a technology that supports asynchronous requests. In short, XmlHttpRequest allows you to use JavaScript to make requests to the server and handle the response without blocking the user. AJAX allows web pages to be updated asynchronously by exchanging a small amount of data with the server in the background. <br /> </p>

SEO course basic handouts<br /> Xiaomian would like to waste some words here. Many people who build websites don’t even know what SEO is, so I would like to educate you on this relevant knowledge. <br /> <br /> SEO is the abbreviation of "Search Engine Optimization", translated as search engine optimization, also called website optimization. SEO sometimes refers to search engine optimizer, that is, search engine optimizer. <br /> <br /> Many people only know that SEO is called search engine optimization, but they don’t know what search engine optimization is. Search engine optimization is actually about optimizing the website itself to conform to the search habits of search engines, so as to obtain better search engine rankings. To be more precise, search engine optimization must not only conform to the search habits of search engines, but also the search habits of netizens. <br /> <br /> Only by doing this can the role of search engine optimization (SEO) be truly reflected. Through search engine optimization, not only should the website obtain a good search engine ranking, but it should also enable the website to obtain more business opportunities and benefits. Although Xiaomian doesn’t pay much attention to PR. I even said that I simply don’t like it. But for everyone’s sake, let’s simply repeat it. <br /> <div> <br /> </div>

Nowadays, many websites cannot achieve profitability, mainly due to lack of planning, lack of market analysis, and lack of website promotion experience. Today, I will introduce the general process of website creation through Huicui.com, so that webmasters can understand the process of website creation, and at the same time, they can reasonably plan the site, organize capital investment, etc. 1. Market analysis and positioning of the needs of the website. For example, Huicui.com, what is the work of the webmaster? What's the situation in the mall now? Can you start a business on the Internet? What is the purpose of creating a website? The work of a webmaster can be said to be a very full job, from IT job websites Tencent Technology and Sina Technology to webmaster-related Webmaster Home, A5 Webmaster Network, and countless webmaster-related websites, here The job market of being a webmaster is indeed not very easy, so why should I create Huixibang.com? At that time, no matter what the market was, it had basically been monopolized by professional websites in large aspects. There were still opportunities for development in more subdivided markets, so we chose to be a webmaster help center. At that time, Baidu webmaster help center only involved To learn about Baidu, we will serve as a help center for all webmasters, providing tutorials and related collaborative guidance on all aspects of website creation.

In the era of DIV CSS, having a thoughtful CSS manual will greatly increase the efficiency of web design. At present, the most commonly used one on the market is the "CSS 2.0 Chinese Manual" produced by Su Chen Xiaoyu, and I have been using it for four or five years. The manual uses CHM format and is very rich in content, including almost all content of CSS2. The only regret is that the manual does not provide the indexing function of the CHM file format. Every time you look for an attribute, you need to classify it, but many times you don't know which category it belongs to. <br /> <br /> So I took the time to add an indexing function based on the "CSS 2.0 Chinese Manual". The copyright of this file is jointly owned by Su Chen Xiaoyu and Jet Mah. I hope everyone will enjoy using it! <br />

The improvement of the quality of web pages helps to obtain good ranking and display in search engines, thus attracting more users and obtaining more traffic. Baidu Search has developed a set of standards for judging the quality of web pages based on users' actual feelings about different web pages. Based on this standard, Baidu Search's collection, sorting, and display environment have been adjusted to give high-quality web pages more opportunities to be included and displayed. , and at the same time suppress some bad and low-quality web pages that affect user experience and deceive search engines. Currently, only 7% of web pages on the Internet can meet high quality standards. As the largest Chinese search engine, Baidu hopes to work with webmasters to build a good Internet ecosystem from the perspective of Internet ecology and better serve netizens. , and also allow websites with high-quality content to develop better.

front end<br /> Web applications are classified as distributed applications, usually with a client-server structure, so some of our code runs on the client and another part of the code runs on the server. Those applications on the client are the front-end, which usually refers to our browser. The most commonly used technology for front-end development is HTML CSS JavaScript. Advanced front-end developers usually use a combination of these technologies to develop the front-end of applications. Another common front-end technology is to use Photoshop design and cooperate with other technologies to complete the production of Web pages. <br />

Are you learning CSS layout? Are you still unable to fully 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, and then add CSS for the 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 properties (such as cellpadding, hspace, align=left, etc.) and don't know what CSS statements to convert them into. Once you have solved the first problem and know how to structure your HTML, I will give you a list detailing what CSS to use to replace the original presentation attributes. <br /> <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 or Fireworks to draw it and cut it into small pictures. Finally, edit the HTML to restore all the designs to the page. <br /> <br /> If you want your HTML page to be laid out with CSS (it is CSS-friendly), you need to go back and start over. Don't think about "appearance" first, but first think about the semantics and structure of your page content. <br />
