A List Apart
Justin James is the Lead Architect for Conigent.
You know - when you've completely forgotten that dodge that really worked, that bit of code you used last month or that syntax that you can't quite recall?
This may be linked on one of the mentioned sites, but I find this very helpful in coding for browser compatibility: http://caniuse.com/
I use the following web site for all webmaster needed resources: http://www.800-webdesign.com/free-webmaster-resources.html It has a large list of free and commercial resources for every aspect of web design
Localization sounds easy, but it isn't. Simple translation into another language is likely to do more harm than good. My preferred site on those issues is http://www.seo-translator.com
I've found myself countless times working on different projects. http://www.w3schools.com
I've been looking to compile such a list for a very long time but it's harder to do than it sounds. -Leo
Useit.com is a great tool and Jacob is one of my all time guru gods but, Vince Flanders webpagesthatsuck.com should be on this list. I've been using the web since before it was the web and all too often I've come across site designs that need to be banned from the internet and their webmasters keelhauled. The sad thing is that many of these are business websites, official City or County pages, and even universities. At Mr Flanders site you get to see the best of the worst. To my mind that's a great tool for learning what not to do in web design - All of the other sites here only show the good stuff.
You have chosen some very interesting (and helpful) websites for the designer, webmaster - beginner or Pro alike in HTML. While I realize a list like this is difficult as there are thousands of reference websites out there, I do feel that a website that features CSS and everything just CSS was missed. I have a suggestion and this is: Stu Nicholls | CSSplay | Experiments with cascading style sheets | Doing it with Style! which is found at: http://www.cssplay.co.uk/ Mr. Nichholls has operated this website for many years with his focus being anything that can be done in HTML can be accomplished using CSS and for the most part, he has proved this. It is a VERY comprehensive and well done website providing hundreds of examples in how using CSS we can accomplish what we only thought was the impossible.
I love the site CSS Zen Garden, because you can see CSS coding in action - every page uses the same HTML, only the CSS is different: http://www.csszengarden.com/. This Web Design Group (WDG) page is also useful, as it lays out the various options for CSS tags: http://www.htmlhelp.com/reference/css/all-properties.html.
