网站建设中最常见的HTML标记语言由于之前有太多的局限性，因此不得不经过层层改进以适应网站的需要，直到现在出现的HTML5，对网站的实现有更大的价值和意义，在结构方面有利于搜索引擎的优化，帮助网站提升了一个阶层。使用HTML5的好处如下：
Site construction in the most common HTML markup language because before there are too many limitations, so have to go through layers of improvement to meet the needs of the site, until now appear HTML5, to the site to achieve greater value and significance, in terms of structure is conducive to search engine optimization, to help web site to upgrade a class. The benefits of using HTML5 are as follows:
1、HTML5在网站建设的使用中更加灵活和自由，为建设者提供了更多功能上的优势，包括各类数据以及应用接口的开放等。众所周知，网站一般不允许在页面中插入Flash和video，这些对于搜索引擎的抓取都是不利的，但对于某些网站来说，又不得不使用这些元素，恰好通过HTML5得到了改善，新标签
和 的加入解决了这些问题，提高了用户体验的同时也有利于搜索引擎的优化。
1, HTML5 in the use of the website construction more flexible and free, to provide the builders with more features, including the advantages of various types of data and application interface, etc.. As we all know, the site is generally not allowed to insert Flash and video in the page, which is the search engine crawl is bad, but for some sites, but also have to use these elements, just through HTML5 has been improved, the new label
2、之前使用html语言时由于存在一些漏洞，网站建设在实现某些功能事都是通过div来定义，难免会造成冗余代码的堆积，而现在的HTML5增加了标签 header, footer, dialog, aside, figure 等，方便定义相应的功能，代码结构更加简洁，使用更加方便快捷。
2, before the use of HTML language because there are some loopholes in the implementation of some of the functions are defined by div, will inevitably lead to the accumulation of redundant code, and now the HTML5 footer, header, dialog, aside, figure, etc., to facilitate the definition of the function, the code structure is more simple, more convenient and quick.
3、网站内容展示更加丰富，HTML5取代了绝大部分的多媒体框架，用户不必担心将多媒体元素放置在页面中导致网站加载速度过慢的局面，因为它是web标准页面的主要体现，拥有完整的程序编写环境，对于多媒体元素，它可以很好的处理，加上微数据的等方面的支持，已经适用于各大主流的浏览器，呈现在用户面前的网站自然丰富多样。
3, the site content is more rich, HTML5 replaced the vast majority of multimedia framework, users do not have to worry about the multimedia elements placed in the page to load the slow speed of the situation, because it is the main web standard pages, has a complete programming environment, for multimedia elements, it can be a very good deal, with the support of micro data, has been applied to the major mainstream browsers, web site in front of the user is rich and varied.
4、HTML5页面支持屏幕自主适应，可根据屏幕的大小自动调整网页布局，适应各种不同设备的页面展示，也即是响应式设计的一大应用。根据这一特性，HTML5将来可能更多的会被应用于移动端，因为目前这种网页在移动端可直接进行调试和修改，方便开发者解决网站**现的问题，减少时间和成本，而且这一应用，网站开发则无需再去考虑针对不同的设备开发新版本的问题，省去了建站的麻烦。
4, HTML5 page to support the screen to adapt automatically according to the size of the screen automatically adjust the layout of the web page to adapt to a variety of different devices of the page display, which is a response to the design of a large application. According to this feature, HTML5 may be more likely to be applied to the mobile terminal, because at present this page can be directly debug and modify the mobile terminal to facilitate developers to solve the problem, reduce the time and cost, and this application, web site development will not need to consider the development of new version of the new version of the problem, eliminating the need for the establishment of the problem.
从实用性方面来看，HTML5的推出，对超文本标记语言的文档作了简化，页面设计复杂程度降低，且最为突出的是应用广泛;从建站角度来看，各种复杂的网站结构代码变得简洁，各种复杂样式可用新标签代替，更容易读懂和分析;从用户体验角度来看，制作出来的页面流畅得多，看到的页面不再生硬，多媒体元素的展示更能吸引用户驻足浏览。
From the practical point of view, the introduction of HTML5 hypertext markup language document makes a reduction, and the most prominent is the application; from the point of view, all kinds of complex web structure code becomes simple, all kinds of complex patterns can be used to replace, more easy to read and analysis; from the user experience point of view, produced more pages are more smooth, see the page is not hard, the display of multimedia elements can attract users to stop browsing.
将来HTML5的使用可能会成为一种主流的网站建设趋势，尤其展现在移动端的网站开发上，实现web端与移动端无缝网络的用户体验。
The use of HTML5 in the future may become a mainstream website construction trend, especially in the mobile terminal development, the realization of the web side and mobile terminal seamless network user experience.
