Developer Tools - W3C Developers

To ask a question to the W3C Community, we invite you to use the w3c tag. Ask a question Contribute Developers are welcome to get involved by contributing code, either to existing tools or proposed future projects. Testing, bug reports, suggestions, or help in creating good documentation are also important! You will find more information to get started in each project on their own web page. Find projects on Github Donate Good tools cost a lot to develop, support, host and maintain. With your help, we can make the tools and validators better, faster, friendlier, and maintain a great, free service for all of the Web.

Cheatsheet. The encoding used for an HTML page that contains a form should support all the characters needed to enter data into that form.


This is particularly important if users are likely to enter information in multiple languages. Databases and scripts that receive data from forms on pages in multiple languages must also be able to support the characters for all those languages simultaneously. The simplest way to enable this is to use Unicode for both pages containing forms and all back-end processing and storage.

In such a scenario the user can fill in data in whatever language and script they need to. You should also try to avoid making assumptions that things such as the user's name and address will follow the same formatting rules as your own. Can I use... Support tables for HTML5, CSS3, etc. JS Bin - Collaborative JavaScript Debugging. Getting Started with SCORM: How does SCORM really work? Coming from a heavy development background I was used to having either code samples available or a very clear explanation of a technology’s inner workings.

Getting Started with SCORM: How does SCORM really work?

When it came to SCORM the only information I could find discussed the protocol at a very high and theoretical level (such as the SCORM specification itself). Uncovering the nuts and bolts of how data bubbled up from the SCO (e.g. the course) to the learning management system (LMS) seemed almost impossible. That was nearly a decade ago and the availability of information has definitely increased since then.

Even still, in the eLearning world the ins and outs of how SCORM actually works continues to be a bit of "black magic" that is hard to break into. I’m hoping we can begin to change that. So let’s start at the beginning. Getting Started with SCORM: Tracking Course Specific Data. We previously discussed how a SCO finds the LMS API, the basics of how to send/retrieve data and touched on the SCORM data model.

Getting Started with SCORM: Tracking Course Specific Data

We are going to build on some of those concepts today and dive into the nuts and bolts of how a SCO uses the SCORM data model to track course data in the real world. If you take the time to read the full SCORM spec and look at the data model (available at: you will notice a long laundry list of available variables that are supported.

These variables define the pieces of information a SCO can retrieve from the LMS, or send to the LMS and ask the LMS to store for future use. The great news is that the vast majority of courseware - whether custom built or created using a tool like articulate or captivate - only use a small subset of these variables. I'm sure when they were writing the spec some of the data model items sounded like great ideas. Most of the items in the data model have a very specific purpose. So what does this look like? #1) viewed=1,2,3. HTML elements reference - HTML: Hypertext Markup Language. This page lists all the HTML elements, which are created using tags.

They are grouped by function to help you find what you have in mind easily. An alphabetical list of all elements is provided in the sidebar on every element's page as well as this one.

GitHub es sin duda la mejor fuente de información para saber qué están haciendo los desarrolladores a nivel mundial ya que es la herramienta de control de versiones más popular y utilizada por desarrolladores y proyectos Open Source. HTML - Aprende sobre desarrollo web. ¿Quieres transformarte en un desarrollador de la interfaz de usuario web? Para crear sitios web, debes conocer el HTML — la tecnología fundamental que se utiliza para definir la estructura de una página web. HTML se utiliza para especificar si tu contenido web se debe reconocer como un párrafo, lista, encabezado, enlace, imagen, reproductor multimedia, formulario o uno de los muchos otros elementos disponibles o incluso un nuevo elemento que tú definas.

Lista de Elementos HTML5 - HTML. Todos los elementos del estandar HTML5 están listados aquí, descritos por su etiqueta de apertura y agrupados por su función. Contrariamente al indice de elementos HTML el cual lista todas las posibles etiquetas, estandar, no-estandar, válidas, obsoletas o aquellas en desuso, esta lista solamente los elementos válidos de HTML5.
