Improving HTML5 Canvas Performance. Introduction HTML5 canvas, which started as an experiment from Apple, is the most widely supported standard for 2D immediate mode graphics on the web. Many developers now rely on it for a wide variety of multimedia projects, visualizations, and games. However, as the applications we build increase in complexity, developers inadvertently hit the performance wall. There’s a lot of disconnected wisdom about optimizing canvas performance. This article aims to consolidate some of this body into a more readily digestible resource for developers. This article includes fundamental optimizations that apply to all computer graphics environments as well as canvas-specific techniques that are subject to change as canvas implementations improve. Note that this article does not go into usage of HTML5 canvas. Performance testing To address the quickly changing world of HTML5 canvas, JSPerf (jsperf.com) tests verify that every proposed optimization still works.

User agents are not required to present HTML documents in any particular way. However, this section provides a set of suggestions for rendering HTML documents that, if followed, are likely to lead to a user experience that closely resembles the experience intended by the documents' authors.
So as to avoid confusion regarding the normativity of this section, RFC2119 terms have not been used. Instead, the term "expected" is used to indicate behavior that will lead to this experience. For the purposes of conformance for user agents designated as supporting the suggested default rendering, the term "expected" in this section has the same conformance implications as the RFC2119-defined term "must". 10.1 Introduction In general, user agents are expected to support CSS, and many of the suggestions in this section are expressed in CSS terms. An element is being rendered if it has any associated CSS layout boxes, SVG layout boxes, or some equivalent in other styling languages. presentational hints. 24 Ejemplos de HTML5 & jQuery & CSS3… Alucinante !!! | Blog de Diseño Web. 24 Ejemplos de HTML5 & jQuery & CSS3… Alucinante !!! El diseño webestá en constante evolución. La aparición hace unos años del jQuery y CSS3, unido a las mejoras introducidas (aunque todavía ridículas) en las velocidades de conexión, han supuesto un cambio radical en la concepción de diseños web.
Ahora con la implantación cada vez mayor de las webs hechas con HTML5, llegamos a un periodo en el que “todo es posible“. Con un poco de imaginación y atractivos diseños, vamos a ver una total revolución en el diseño web, sobre todo en la usabilidad. A continuación os dejo con 24 ejmplos de páginas web realizadas en HTML5, jQuery y CSS3, que me han sorprendido mucho, estamos entrando en una nueva fase de diseño y usabilidad, en la que ya no hace falta pulsar sobre un botón para realizar una acción, en la que podremos interactuar mucho más con la web y dejar de ser meros espectadores.
Labs - Joe Critchley • Interface Developer. JavaScript. JavaScript (JS) is a lightweight interpreted (or just-in-time compiled) programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, single-threaded, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles. JavaScript's dynamic capabilities include runtime object construction, variable parameter lists, function variables, dynamic script creation (via eval), object introspection (via for...in and Object utilities), and source-code recovery (JavaScript functions store their source text and can be retrieved through toString()).
This section is dedicated to the JavaScript language itself, and not the parts that are specific to Web pages or other host environments. Looking to become a front-end web developer? Get started. Tipos de fuentes en css « Don Estándares. Holas :) en css se plantea mucho sobre las fuentes, lo ideal… es usarle las propiedades del css para que se vea bonito al usuario, y para nosotros fácil de manejar. El css nos da la flexibilidad de poder darle color, tamaño, grueso y otras propiedades que trataremos de explicarlas, no todas :p por que son demasiadas pero si las mas importantes.
Recuerda algo, por el momento no se pueden usar fuentes que el visitante no tenga instaladas, por ejemplo este tipo de letra, es muy bonita y hasta agradable, pero el problema es que si nosotros la instalamos en nuestra pc y trabajamos con css o en html con ese tipo de letra y la subimos a un servidor, esta en NUESTRA PC se va a ver muy bien, el problema es cuando nuestros usuarios abran nuestro sitio web, ellos no verán correctamente por que en la pc del usuario no esta instalada esta fuente. principalmente las fuentes default son: Arial, Helvetica, sans-serif Y que pasa si en el sistema operativo (Mi preferido :P Linux!
