Tecnologia da Web para programadores

A natureza aberta da World Wide Web apresenta oportunidades incríveis para as pessoas que desejam criar sites da Web ou aplicações on-line. Para tirar o máximo partido das capacidades da Web, precisa de saber como as deve utilizar. Explore as hiperligações abaixo para saber mais sobre as diferentes tecnologias da Web.

Tecnologias da Web


HyperText Markup Language (HTML) is used to describe and define the content of a webpage.
Cascading Style Sheets (CSS) are used to describe the appearance or presentation of content on a webpage.
Hypertext Transfer Protocol (HTTP) is used to deliver HTML and other hypermedia documents on the Web.


JavaScript is the programming language that runs in your browser. You can use it to add interactivity and other dynamic features to your website or application.
APIs da Web 
Web Application Programming Interfaces (Web APIs) are used to perform a variety of tasks, such as manipulating the DOM, playing audio or video, or generating 3D graphics.
  • The Web API interface reference lists all the object types you can use while developing for the Web.
  • The WebAPI page lists all the communication, hardware access, and other APIs you can use in Web applications.
  • The Event reference lists all the events you can use to track and react to interesting things that have taken place in your webpage or application.


Scalable Vector Graphics (SVG) let you describe images as sets of vectors (lines) and shapes. One advantage of SVGs is that they scale smoothly regardless of the size at which they're drawn.
WebGL is a JavaScript API that lets you draw 3D or 2D graphics using the HTML5 <canvas> element.
