Typographic Scaling and Basic Styles: Using too many font sizes and styles at the same time can easily ruin a layout. Typographic scaling consists of a limited set of font sizes that fit well within the layout structure. The most basic set of styles is based on typographic scaling of 12, 14, 16, 20 and 34 point fonts. <br /> These sizes and styles balance content density and reading comfort in classic applications. Font size is specified through SP (scaleable pixels), allowing larger font sizes to be better accepted. Interested friends can come and take a look

Web programming technology and examples (Tan Haoqiang)

<p> Part of this article is quoted from the famous domestic front-end development siege master----Cao Liuyang (Adang). He once published the book "Writing High-Quality Code--The Way of Cultivation of WEB Front-end Development" and became very popular. He now works for Shanda Innovation hospital. According to the evaluation of a domestic survey agency, the content involved in this article is worth over RMB 10,000 in the IT training industry. Adhering to the great spirit of teacher A Dang's knowledge sharing, part of the content is now published to share learning with all children. </p> <p> With the development of technology, front-end requirements are becoming more and more complex. The functions and products that can be implemented on the front end are becoming more and more powerful and abundant. For example: Sina Weibo's in-webpage chat tool, Google Maps, page music player and the more powerful WEB-QQ, etc. The arrival of HTML5 and CSS3 at lightning speed is more like a heavy bomb, which has had an immeasurable impact and expectation on website development and design.

Ajax stands for "Asynchronous Javascript And XML" and refers to a web development technology for creating interactive web applications. <br /> Ajax = Asynchronous JavaScript and XML (a subset of Standard Universal Markup Language). <br /> Ajax is a technology for creating fast, dynamic web pages. <br /> Ajax is a technology that allows you to update parts of a web page without reloading the entire page. <br /> Ajax allows web pages to update asynchronously by exchanging a small amount of data with the server in the background. This means that parts of a web page can be updated without reloading the entire page. <br /> Traditional web pages (without Ajax) must reload the entire web page if content needs to be updated. <br />
