You can pick more than one answer on the multiple choice questions.
I'm looking to get a couple of site ideas TODAY if possible. We are wanting to launch this new section very, very soon - like possibly next week -- so this is a chance to get your site "spotlighted" among the first ones!
One problem I've found with developing HTML5/CSS3 web sites is validation:
a) The excellent WDG HTML validator (which will validate a whole site in one go) is not HTML5 compliant.
b) The W3C HTML5 validator will validate only one web page at a time.
This makes validating a cumbersome process, particularly when you need to validate CSS3 and the links as well. I can't do anything about the limitation of validating one page at a time, but I have written a front-end for the W3C validators that:
a) Will validate the HTML, CSS and/or links of a web page in one go.
b) Uses pick lists to select the web page to validate.
c) Dynamically generates the pick lists from sitemap files in text or XML format.
d) Has ">" (next) and "<" (previous) buttons to allow you to step through validating a sequence of pages without having to pick each one from the pick list.
I would be grateful if people who have or are developing HTML5/CSS3 sites would give the front-end a try, particularly if you have already set up a sitemap of a small to medium size site.
a) It still will not validate a whole site in one go.
b) Once they are generated, the pick lists are passed via the GET mechanism, (to avoid re-reading the sitemap files every time). That limits the size of the pick lists that can be used.
c) The "Validate" button may not work sequentially on the same file. The work-around is to use F5 to repeat a validation.
