“CSS class” is a misnomer; class is an attribute (or a property, in terms of scripting) that you assign to HTML elements. In other words, you declare classes in HTML, not CSS, so in your case the “target” class does in fact exist on those specific elements, and your markup is perfectly valid as it … Read more
Explicitly Target IE versions without hacks using HTML and CSS Use this approach if you don’t want hacks in your CSS. Add a browser-unique class to the <html> element so you can select based on browser later. Example <!doctype html> <!–[if IE]><![endif]–> <!–[if lt IE 7 ]> <html lang=”en” class=”ie6″> <![endif]–> <!–[if IE 7 ]> … Read more
Is one just an extension? Pretty much, yes – RFC 3339 is listed as a profile of ISO 8601. Most notably RFC 3339 specifies a complete representation of date and time (only fractional seconds are optional). The RFC also has some small, subtle differences.

They are also similar to XPath and XQuery conceptually; even though XML and JSON have different conceptual models (hierarchic vs object/struct). EDIT Sep-2015: Actually there is now JSON Pointer standard that allows very simple … Read more
I would always encode in UTF-8. From the Wikipedia page on percent encoding: The generic URI syntax mandates that new URI schemes that provide for the representation of character data in a URI must, in effect, represent characters from the unreserved set without translation, and should convert all other characters to bytes according to UTF-8, … Read more
That’s just what the spec says. From the HTML 4 specification: ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens (“-“), underscores (“_”), colons (“:”), and periods (“.”). The good news is that the HTML 5 specification is more lenient: The id … Read more
http://www.w3.org/TR/html4/interact/forms.html#h-17.5 Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to “image”, but the BUTTON element … Read more
