Quick Tip
CSS - when using more than one way to apply a style, be 
sure to understand style precedence. Inline styles will take precedence over embedded. Embedded will take precedence over external. For the most part, web sites are easier to work with and maintain when most if not all the styles are on an external style sheet in one place . . . then precedence is not an issue.

HTML5: Development
1990s
- Manufacturers and community members were responsible for much of the evolvement of HTML.
- Proprietary features released by browser manufactures. These features were not supported by competing browser manufactures, causing headaches for Web designers and developers.
1995- 1997
- First standardized release of HTML, known as HTML 2.0. The current rules everyone was already using became the standard.
- HTML 3 recommendations were never adopted.
- HTML 3.2 included features that browsers already supported, like tables and applets.
- Browser manufacturers continued to release their own proprietary tags and offer different levels of support for certain features. This forced Web designers and developers to create different versions of their sites to support different browsers.
1997-1999
- HTML 4 became recognized standard.
- A group of Web professionals started the Web Standards Project. These professionals pushed for standards and made recommendations to the World Wide Web Consortium (W3C). Much more pressure was put on browser manufacturers to support the standards.
2000
- XHTML 1.0 released by W3C to replace HTML 4 as the standard. XHTML is an XML (Extensible Markup Language) version of HTML. XHTML was stricter than HTML; tags must be written in lower case, empty elements must be closed, ID attributes used instead of Name, etc.
- XHTML was not a dramatic departure from HTML 4 and most browsers rendered XHTML as HTML.
2006
- W3C announced they would work with WHATWG (Web Hypertext Application Technology Working Group), a group of developers and designers, to evolve HTML rather than XHTML.
2007
- W3C created first working draft of HTML5 specifications.
2009
- XHTML 2.0 was not backward compatible and designers and developers were slow to adopt, even after years of work.
- WHATWG was unhappy with the direction of XHTML 2.0 and continued with the development of HTML.
- XHTML 2.0 ended before browsers supported it.
- WHATWG efforts were finally recognized by W3C . The developments were adopted under the name HTML5.
2010 - Current
- Interest in HTML 5 exploded, sped up by strong pushes from Apple and Google.
- HTML5 is backwards compatible with previous versions of HTML.
- Contains new structural tags and support for APIs (Application Program Interface), making it easier for designers and developers to build web and mobile applications, serve video and audio, and create richer user experiences for sites.
- Specifications are over 900 pages long, twice the length of HTML4.
