HTML5 introduces many cutting-edge features that enable developers to create apps and websites with the functionality, speed, performance, and experience of desktop applications. But unlike desktop applications, apps built on the web platform can reach a much broader audience using a wider array of devices. HTML5 accelerates the pace of your innovation and enables you to seamlessly roll out your latest work to all your users simultaneously.

HTML-Kit is a full-featured website editor first, but it can handle other types of text files as well.

HTML-Kit has received 95% thumbs up on Download.com. You can find mentions of HTML-Kit in 200+ books.

starting html/css template. so much goodness baked in by default

Welcome to HTML Dog, the web designer's resource for everything HTML and CSS, the most common technologies used in making web pages.

In this post we present a new speedy way of writing HTML code using CSS-like selector syntax — a handy set of tools for high-speed HTML and CSS coding. It was developed by our author Sergey Chikuyonok and released for Smashing Magazine and its readers.

HTML Lint is a tool that makes sure your code looks good. While XHTML was very strict with syntax HTML 5 is more lenient like previous versions of HTML, which means keeping consistent code styles will become more difficult. Validating is not good enough anymore.

Bluefish is a powerful editor targeted towards programmers and webdesigners, with many options to write websites, scripts and programming code. Bluefish supports many programming and markup languages, and it focuses on editing dynamic and interactive websites.

Living Standard — Last Updated 22 January 2011

You can take part in this work. Join the working group's discussion list.
Web designers! We have a FAQ, a forum, and a help mailing list for you!

we are today announcing two changes:

1. The HTML specification will henceforth just be known as "HTML", with the URL http://whatwg.org/html.

2.The WHATWG HTML spec can now be considered a "living standard".

This tip demonstrates how to convert HTML documents to XML (or more specifically, XHTML) with a simple, open source tool, HTML Tidy. This conversion is useful for webmasters who are migrating to XML. It can also help XML converts who have to interface with legacy HTML tools.

Formatting a Bibliography from a List of References

HTML Dog has been dishing out healthy code treats since 2003, and currently serves up around 1,500,000 page views a month. The idea is to take the somewhat convoluted official specs for XHTML and CSS and present them in a much more readable fashion.

We are passionate about the web, learning, and craftsmanship. We want you, as web designers and developers, to be successful in your careers. We feel, though, that W3Schools is harming the community with inaccurate information. Like any other authoritative educational resource, W3Schools should both hold itself to, and be held to, the highest standards.

We hope we can illuminate why W3Schools is a troublesome resource, why their faulty information is a detriment to the web, and what you (and they) can do about it.

In this article you'll learn about 2 popular alternatives to WYSIWYG editors: Textile and Markdown. You'll learn what they are, how to install them, and how to use them. You'll also compare them to each other, and to using WYSIWYG editors. The article ends with lots of useful links to help you find out more about Textile and Markdown

Textile takes plain text with *simple* markup and produces valid XHTML. It's used in web applications, content management systems, blogging software and online forums. Try it for yourself with the Textile quick reference and preview.

Mozilla Skywriter (formerly codenamed Bespin) is a fast, customizable programmer's editor, written for modern web browsers. With it, you can enable "coding in the cloud" on your website (using Skywriter Embedded) or on any website (using Skywriter Bookmarklet)

KompoZer is a complete web authoring system that combines web file management and easy-to-use WYSIWYG web page editing.

Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).

Wickham's HTML & CSS tutorial

Webby is a fantastic little website management system. It would be called a content management system if it were a bigger kid. But, it’s just a runt with a special knack for transforming text. And that’s really all it does – manages the legwork of turning text into something else, an ASCII Alchemist if you will.

Webby works by combining the contents of a page with a layout to produce HTML. The layout contains everything common to all the pages – HTML headers, navigation menu, footer, etc. – and the page contains just the information for that page. You can use your favorite markup language to write your pages; Webby supports quite a few.

AHAH: Asynchronous HTML and HTTP
AHAH is a very simple technique for dynamically updating web pages using JavaScript. It involves using XMLHTTPRequest to retrieve (X)HTML fragments which are then inserted directly into the web page, whence they can be styled using CSS.

In the last article, we touched briefly on the basic building blocks of the web—HTML (or XHTML), CSS and JavaScript. Now it’s time for me to dig a little deeper and to look at each of these—what they do, and how the three interact with each other to create a web site.

Opera has created the Web Standards Curriculum (WSC) in association with the Yahoo! Developer Network. This tutorial course takes students from complete beginner to having a solid grounding in standards-based Web design, including HTML, CSS, and JavaScript development. The course is supported by top companies and organizations such as the Web Standards Project (WaSP) and Yahoo!.

Split into more than 50 focused articles, students can follow the curriculum from start to finish or simply read articles that interest them the most. Each article contains essential theory, practical examples, and exercise questions.

With Aardvark, you can select elements on a web page (for instance, a static html mockup of parts of your Ajax application), press J, and get Javascript code to dynamically generate identical elements. Unlike typical DOM techniques, it isn't hard to look at or tedious to work with, in fact, the code generated looks nearly identical to the equivalent HTML. You may then paste this code into your DHTML/Ajax application, hook it up appropriately, and tweak it to your heart's desire.

HTML5 Boilerplate is the professional badass's base HTML/CSS/JS template for a fast, robust and future-proof site.

Today’s Graphics Dojo example is related to WebKit (again), namely using it as a basis for WYSIWYG (what-you-see-is-what-you-get) editor. Thanks to Apple engineers and other WebKit hackers, WebKit’s editing features have improved a lot so that it is perfectly possible to use it to let the user edit the web page.

A vocabulary and associated APIs for HTML and XHTML

Abstract

This specification defines the 5th major revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features are introduced to help Web application authors, new elements are introduced based on research into prevailing authoring practices, and special attention has been given to defining clear conformance criteria for user agents in an effort to improve interoperability.

HTML5 is a new version of HTML and XHTML. The HTML5 draft specification defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML.

Looking for a better editor (or perhaps even your first editor) to design your website? This page lists free HTML editors, Web editors, WYSIWYG editors, web site builders, as well as specialized editors optimized for Cascading Style Sheets (CSS) or even the numerous web scripting languages such as PHP, Perl, Java, JavaScript, ASP, etc.

I can’t believe a new feature from Google isn’t getting more notice, because it converts already-existing links to your site into much higher quality links, for free. The Google webmaster blog just announced that you can find the pages that link to 404 pages on your site.

Aptana Studio is a complete web development environment that combines powerful authoring tools for HTML, CSS, and JavaScript, along with thousands of additional plugins created by the community.
