CSS3, Web Fonts and Icons

Nowadays, we have so many new tips and techniques and ways of working all of the time.

More than ever before. CSS3 is one of those (slightly) new great technologies. Along with it have come a whole host of things which make our lives easier as both designers and developers. However, we’re also in an age where we’re designing for more users, devices, browsers and technologies than we ever have done before. Nowadays we have thousands of different devices, screen sizes and contexts that we’re expected to cater for. Our Process Must Adapt And what does this mean for our process?

是指为了从搜索引擎中获得更多的免费流量,从网站结构、内容建设方案、用户互动传播、页面等角度进行合理规划,使网站更适合搜索引擎的检索原则的行为。 使网站更适合搜索引擎的检索原则又被称为对搜索引擎友好,对搜索引擎友好不仅能够提高SEO的效果,还能提高用户体验,因为这样会使搜索引擎中显示的网站相关信息对用户来说更有吸引力。 为了说明什么是网站对搜索引擎友好,我们不妨看看对搜索引擎不友好的网站有哪些特征: 1、网页中大量采用图片或者Flash等富媒体(Rich Media)形式,没有可以检索的文本信息,而SEO最基本的就是文章SEO和图片SEO; 2、网页没有标题,或者标题中没有包含有效的关键词; 3、网页正文中有效关键词比较少(一般小于整文章2%~8%); 4、网站导航系统让搜索引擎“看不懂”; Website. homepage A website, also written as Web site,[1] web site, or simply site,[2] is a set of related web pages served from a single web domain.


A website is hosted on at least one web server, accessible via a network such as the Internet or a private local area network through an Internet address known as a Uniform resource locator. All publicly accessible websites collectively constitute the World Wide Web. A webpage is a document, typically written in plain text interspersed with formatting instructions of Hypertext Markup Language (HTML, XHTML). A webpage may incorporate elements from other websites with suitable markup anchors. Webpages are accessed and transported with the Hypertext Transfer Protocol (HTTP), which may optionally employ encryption (HTTP Secure, HTTPS) to provide security and privacy for the user of the webpage content. The pages of a website can usually be accessed from a simple Uniform Resource Locator (URL) called the web address. HTML <area> 标签. 实例 带有可点击区域的图像映射: 亲自试一试 浏览器支持 所有主流浏览器都支持 <area> 标签。

Introduction As an experienced developer, you will sooner or later have to face people that are just not technical and will consider whatever you do as black magic.
