Old ground, worth covering again.

I can see this being horribly confusing.

"A program for converting between various markup formats. Input formats include markdown, reStructuredText, HTML, and LaTeX; output formats include HTML, LaTeX, ConTeXt, S5, DocBook, groff man, reStructuredText, markdown, and RTF."

"Once HTML 5 becomes a viable option, how can we avoid having teams of web developers spending their time discussing which syntax to use instead of working on the project their clients pay for?"

Not entirely sure I agree with everything in this but worth a gander.

Just the meat. "This specification describes the fifth major version of the HTML language and provides details necessary for producers of HTML content to create documents that conform to the language. By design, it does not define related APIs nor attempt to specify how consumers of HTML content are meant to process documents."

"...seeks to elaborate on a hand-picked Selection of features from the HTML 5 specification and other fine Standards. I shall publish Drafts periodically, as time permits."

Why Dave Shea is switching from XHTML to HTML.

"When you care about performance, or SEO (or just doing a good job as web dev) an interesting data point is the ratio of page content vs. the markup used to present this content. Or... how much crap we put in HTML in order to present what the users want to see - the content."

Interesting way of using twitter to conduct polls, plus a debate that goes on and on (2p: main title, not logo! Otherwise you have the same h1 across all pages on a site).

"Validator S.A.C. (Stand Alone Complex) is a stand-alone, easy to install, version of the W3C's HTML / XHTML Markup Validator for Mac OS X."

Lipsum snippets for copying, with TextMate bundles.

"This demo shows how compound microformats can be used to progressively enhance HTML with semantic meaning."

Good comparison of the two specs.

"or How to be a POSH SEO!"

"Make any errors or suspicious markup obvious to the person working on the document." Been doing this for a while - had lost the original source.

"The Sandbox is a theme for themers. It has the ability to be easily skinned, so beginners will feel comfortable styling it since they only need to know CSS. More experienced designers will drool at the rich semantic markup."

POSH encapsulates the best practices of using semantic HTML to author web pages. Semantic HTML is the subset of HTML 4.01 (or XHTML 1.0) elements and attributes that are semantic rather than presentational.

"Different ways to clear floats without any extra mark-up." Good reminder.

"Surely if you are part of implementing a website or even maintain your own blog, good practice typography should be a part of it?"

Nothing new but that's not a criticism; good to have all this in one place!

"The problem is, everyone’s doing it wrong."

"There is another kind of editor that is better suited than WYSIWYG for content-driven, client-edited sites - the WYSIWYM (What You See Is What You Mean) editor."

Big list of microformats resources

"This article highlights and answers some of the most frequently asked questions about HTML. HTML is the foundation of the Web, and both developers and designers need to understand it."

"Unless you have lots of legacy content that contains presentaional markup and cannot easily be converted or cleaned up, go Strict"

"In their eagerness to be good Web citizens, people sometimes use semantic markup when they shouldn’t. Most commonly, this happens with bold and italics."

"A quick look at what microformats are and aren’t, then we’ll look at some very significant organizations already using them. Then we’ll take a look at just how easy it is to use them."

"Although Internet Explorer recognises the q element, it doesn't render the quotations marks around the quoted text. A CSS solution isn't possible, as Internet Explorer doesn't support the :before and :after pseudo-elements, so this article suggests a scr

"Here is a summary of 8 steps any web developer can take to improve their page code"

"Trying to build a scalable, maintainable, and extendable user experience on bad markup is like building a house on quicksand."

"There is a danger of adversly effecting semantics through incorrect use of CSS."

"The aim of the "Relaxed" project is to allow automated validation of additional restrictions which are expressed just verbally in the text of different HTML standards."

"More and more web documents are appearing that consist of nothing more than a collection of div elements. In most cases, better use of CSS selectors could be used to avoid overusing the div element."

"On semantic markup, conveying its usage to those who generally don’t need to care, and a reusable markup guide for your enjoyment."
