html5 - What's the key difference between HTML 4 and HTML 5 Polyglot Markup: HTML-Compatible XHTML Documents When applying JavaScript and CSS to polyglot markup, the goal is to get the same result whether consumed as HTML or as XML. It is therefore important to be aware of scripting and styling features that give different results in HTML vs XML. These issues comes in addition to the polyglot usage rules for raw text elements. 4.11.2 CSS: Attribute selectors that require a namespace prefix To be able to select namespaced attributes in XML, the attribute selector must include a namespace prefix. For the unprefixed, namespaced attribute xmlns, a polyglot selector that works in both HTML and XML can be created by using the asterisk (*) for the namespace prefix, indicating that the selector is to match all attribute names without regard to the attribute's namespace: Example 18 Example 19 Note Example 20 In cases where the user agent does not support namespaces in CSS and/or in markup, it is necessary to use more than one selector. Example 21

1 Introduction — HTML5 1 Introduction 1.1 Background This section is non-normative. The World Wide Web's markup language has always been HTML. HTML was primarily designed as a language for semantically describing scientific documents, although its general design and adaptations over the years have enabled it to be used to describe a number of other types of documents. The main area that has not been adequately addressed by HTML is a vague subject referred to as Web Applications. 1.2 Audience This specification is intended for authors of documents and scripts that use the features defined in this specification, implementors of tools that operate on pages that use the features defined in this specification, and individuals wishing to establish the correctness of documents or implementations with respect to the requirements of this specification. In particular, familiarity with the basics of DOM is necessary for a complete understanding of some of the more technical parts of this specification. 1.3 Scope 1.4 History .

Jean Piaget | Cognitive Theory by By Saul McLeod 2009, updated 2015 Piaget's (1936) theory of cognitive development explains how a child constructs a mental model of the world. He disagreed with the idea that intelligence was a fixed trait, and regarded cognitive development as a process which occurs due to biological maturation and interaction with the environment. Piaget was employed at the Binet Institute in the 1920s, where his job was to develop French versions of questions on English intelligence tests. He became intrigued with the reasons children gave for their wrong answers to the questions that required logical thinking. He believed that these incorrect answers revealed important differences between the thinking of adults and children. Piaget (1936) described his work as genetic epistemology (i.e. the origins of thinking). What Piaget wanted to do was not to measure how well children could count, spell or solve problems as a way of grading their I.Q. Piaget's Theory Differs From Others In Several Ways: Schemas

HTML5 This specification defines the 5th major version, second minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability. This section describes the status of this document at the time of its publication. Other documents may supersede this document. This document was published by the Web Platform Working Group as a W3C Recommendation for HTML 5.2 that would obsolete the HTML 5.1 Recommendation. All interested parties are invited to provide implementation and bug reports and other comments through the Working Group's Issue tracker. This document was produced by a group operating under the W3C Patent Policy.
