Why to build the benefits of Web standards and Web standards _ Basic Tutorials

Most of us have a deep experience, and every time a major browser version is upgraded, the site we just built may become obsolete, and we need to upgrade or rebuild the site. For example, the 1996-1999 classic "Browser wars", in order to be compatible with Netscape and IE, the site had to write different code for both browsers. Similarly, whenever new network technologies and interactive devices emerge, we need to create a new version to support this new technology or device, such as WAP technology that supports mobile internet access. Similar problems abound: The Web code is bloated, the complexity of the waste of our large amount of bandwidth, for a browser of DHTML effects, shielding some potential customers, not easy to use code, people with disabilities can not browse the site and so on. This is a vicious circle, is a huge waste.
How do you solve these problems? People of insight have already begun to think and need to establish a universally agreed standard to end this disorder and chaos. Business Companies (Netscape, Microsoft, etc.) have also finally recognized the benefits of a unified standard, Therefore, under the organization of the w3c.org, the website standard began to be established (February 10, 1998 issued XML1.0 as the logo), and under the supervision of the website Standards Organization (webstandards.org) to promote implementation.
Simply put, the purpose of the website standard is to:
Provide the most benefits to the most users of the site to ensure that any Web site can effectively simplify the code for a long time, reduce the cost of construction to make the site easier to use, adapt to more different users and more network devices when the browser version of the update, or the emergence of new network interaction devices, ensure that all applications For web design and developers, adherence to the Web site standard is the standard; for your site users, the site standard is the best experience.
Benefits of using Web standards
Benefits to Web surfers:
File download and page display faster; content can be accessed by more users (including people with disabilities such as blindness, visual impairment, color blindness); content can be accessed by a wider range of devices (including screen readers, handheld devices, search bots, printers, refrigerators, etc.) users can customize their performance interface through style selection All pages can provide the benefits of a print-appropriate version to the site owner:
Less code and components, easier to maintain bandwidth requirements (simpler code), lower cost. For example: When ESPN.com uses CSS, it saves more than two megabytes (terabytes) of bandwidth per day. Search engine is more easily searchable to the revision of convenience, do not need to change the content of the page to provide a print version without the need to replicate content to improve the usability of the site. In the United States, there are strict legal provisions (Section 508) to constrain government websites to a certain degree of ease of use, and other countries have similar requirements.
