HTML5

HTML5 is a markup language used for structuring and presenting content on the World Wide Web. It was finalized, and published, on 28 October 2014 by the World Wide Web Consortium (W3C). This is the fifth revision of the HTML standard since the inception of the World Wide Web. The previous version, HTML 4, was standardized in 1997.

Its core aims are to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.). HTML5 is intended to subsume not only HTML 4, but also XHTML 1 and DOM Level 2 HTML.

Following its immediate predecessors HTML 4.01 and XHTML 1.1, HTML5 is a response to the fact that the HTML and XHTML in common use on the World Wide Web have a mixture of features introduced by various specifications, along with those introduced by software products such as web browsers and those established by common practice. It is also an attempt to define a single markup language that can be written in either HTML or XHTML. It includes detailed processing models to encourage more interoperable implementations; it extends, improves and rationalizes the markup available for documents, and introduces markup and application programming interfaces (APIs) for complex web applications. For the same reasons, HTML5 is also a potential candidate for cross-platform mobile applications. Many features of HTML5 have been designed with low-powered devices such as smartphones and tablets taken in to consideration. In December 2011, research firm Strategy Analytics forecast sales of HTML5 compatible phones would top 1 billion in 2013.

Cascading Style Sheets

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language. Although most often used to set the visual style of web pages and user interfaces written in HTML and XHTML, the language can be applied to any XML document, including plain XML, SVG and XUL, and is applicable to rendering in speech, or on other media. Along with HTML and JavaScript, CSS is a cornerstone technology used by most websites to create visually engaging webpages, user interfaces for web applications, and user interfaces for many mobile applications.

CSS is designed primarily to enable the separation of document content from document presentation, including aspects such as the layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple HTML pages to share formatting by specifying the relevant CSS in a separate .css file, and reduce complexity and repetition in the structural content, such as semantically insignificant tables that were widely used to format pages before consistent CSS rendering was available in all major browsers. CSS makes it possible to separate presentation instructions from the HTML content in a separate file or style section of the HTML file. For each matching HTML element, it provides a list of formatting instructions. For example, a CSS rule might specify that "all heading 1 elements should be bold", leaving pure semantic HTML markup that asserts "this text is a level 1 heading" without formatting code such as a <bold> tag indicating how such text should be displayed.

CSS (band)

CSS (an initialism of Cansei de Ser Sexy) is a Brazilian rock band from São Paulo. The band was labeled as part of the explosion of the new rave scene. Their songs are in both English and Portuguese. Cansei de Ser Sexy (Portuguese: [kɐ̃ˈsej d(ʒi)seʁ ˈsɛksi], [kɐ̃ˈseɪ̯ dʒɪ seɾ ˈsɛksi] in São Paulo) literally translates as "I got tired of being sexy".

History

2003–06: Formation and Cansei de Ser Sexy (Brazilian album)

CSS formed in September 2003, consisting of a group of friends. Their name was taken from a reported quote by Beyoncé, who allegedly declared that she was "tired of being sexy".

The band first garnered fame through the internet. Some of its members, like Adriano Cintra, and Wendi Bishop, had been previously known in São Paulo's underground club scene, but not outside of the local alternative subculture. Others, like Lovefoxxx, were the owners of popular Fotolog and Flickr pages. Their collective band fotolog also gained popularity and their songs were frequently downloaded from Trama Virtual's website. Several songs by CSS were featured in mainstream media, for example "Meeting Paris Hilton" was featured in the Latin American broadcasting of The Simple Life, "Superafim" was used in the Brazilian version of Big Brother. Still unsigned, they released two independent EPs—Em Rotterdam Já É uma Febre in 2004, and A Onda Mortal / Uma Tarde com PJ in January 2005—and played at the TIM Festival in 2004.
