Web standards checklist. Date: 13 August 2004 Author: Russ Weakley Web standards – more than just ‘table-free sites’ The term web standards can mean different things to different people. For some, it is ‘table-free sites‘, for others it is ‘using valid code‘. However, web standards are much broader than that.
A site built to web standards should adhere to standards (HTML, XHTML, XML, CSS, XSLT, DOM, MathML, SVG etc) and pursue best practices (valid code, accessible code, semantically correct code, user-friendly URLs etc). In other words, a site built to web standards should ideally be lean, clean, CSS-based, accessible, usable and search engine friendly. About the checklist This is not an uber-checklist.

Free online meeting scheduler / meeting planner / date planner / appointment booking tool : my events : AgreeAdate lets you choose whether to list your invitees and send emails to them from within the system, or to use your own email software to send an invitation with a special link.
The advantage of adding the details for each invitee is that agreeAdate knows who they are when they click on their unique link in their invitation email and allows you to send personalised reminder emails, etc. If you don't need this ability and just want to include a single link in an email, blog or web page then use the link provided above. You can mix the two methods if you like, specifying some of the invitees but then distributing the general link for any others that may be interested in attending.
To add invitees into the table above, just type into the empty boxes at the bottom. You can return to this step at any time to add more people. Emails are only sent once you have pushed the button below the table. You can organise your address book contacts into groups. Objects, Images, and Applets in HTML documents. 13.1 Introduction to objects, images, and applets HTML's multimedia features allow authors to include images, applets (programs that are automatically downloaded and run on the user's machine), video clips, and other HTML documents in their pages. For example, to include a PNG image in a document, authors may write: <BODY><P>Here's a closeup of the Grand Canyon: <OBJECT data="canyon.png" type="image/png"> This is a <EM>closeup</EM> of the Grand Canyon.
</OBJECT></BODY> Previous versions of HTML allowed authors to include images (via IMG) and applets (via APPLET). They fail to solve the more general problem of how to include new and future media types. To address these issues, HTML 4 introduces the OBJECT element, which offers an all-purpose solution to generic object inclusion. The new OBJECT element thus subsumes some of the tasks carried out by existing elements. The chart indicates that each type of inclusion has a specific and a general solution.

This is a short introduction to writing HTML.
What is HTML? It is a special kind of text document that is used by Web browsers to present text and graphics. The text includes markup tags such as <p> to indicate the start of a paragraph, and </p> to indicate the end of a paragraph. HTML documents are often refered to as "Web pages". The browser retrieves Web pages from Web servers that thanks to the Internet, can be pretty much anywhere in World. Many people still write HTML by hand using tools such as NotePad on Windows, or TextEdit on the Mac.
P.s. a good way to learn is to look at how other people have coded their html pages. For Mac users, before you can save a file with the ".html" extension, you will need to ensure that your document is formatted as plain text.

The draggable and dropzone attributes These two attributes were placed together since they're part of the new drag and drop API (DnD API). For the draggable attribute, there are three states: true, false, and auto (auto is not a keyword, it's simply the missing value default). According to the W3C HTML5 Working Draft: "The true state means the element is draggable; the false state means that it is not. The auto state uses the default behavior of the user agent. " If you're going to drag something, you need to be able to drop it too. Support for these attributes is good (in all browsers except Opera—including Android), though with dropzone, you will need to get into a bit of JavaScript.
The hidden attribute Here's the W3C HTML5 Working Draft on the hidden attribute: "The hidden attribute is a boolean attribute. Of course, you're going to have to manipulate this attribute with JavaScript.
