Not all core events are listed, but during testing they all worked. Other extended events like onbeforecopy, oncopy, oncontextmenu, and more were also verified as functional under Internet Explorer 8. Element-Specific Attributes cite The value of this attribute is a URL that designates a source document or message that might explain why the information was deleted. datetime This attribute is used to indicate the date and time the deletion was made. The value of the attribute is a date in a special format as defined by ISO 8601. The basic date format is YYYY-MM-DDThh:mm:ssTZD where the following is true: YYYY=four-digit year such as 1999 MM=two-digit month (01=January, 02=February, and so on.) DD=two-digit day of the month (01 through 31) hh=two-digit hour (00 to 23) (24-hour clock, not AM or PM) mm=two-digit minute (00 through 59) ss=two-digit second (00 through 59) TZD=time zone designator The time zone designator is either Z, which indicates Universal Time Coordinate or coordinated universal time format (UTC), or +hh:mm, which indicates that the time is a local time that is hh hours and mm minutes ahead of UTC. Alternatively, the format for the time zone designator could be –hh:mm, which indicates that the local time is behind UTC. Note that the letter T actually appears in the string, all digits must be used, and 00 values for minutes and seconds might be required. An example value for the datetime attribute might be 1999-10-6T09:15:00-05:00, which corresponds to October 6, 1999, 9:15 A.M., U.S. Eastern Standard Time.

This is rarely if ever respected. • The HTML and XHTML strict specifications do not support this element, and the HTML5 specification has marked it as obsolete and suggests using a <ul> tag instead. • Most browsers will not render a <dir> tag any differently from the <ul> tag. • HTML 2 and 3.2 define only the compact attribute. • Most browsers will not render the compact list style. • For XHTML transitional compatibility, the compact attribute must have a value: <dir compact="compact">. <div> (Division) This element indicates a generic block of content that should be treated as a logical unit for scripting or styling purposes.

It complements <span>, which is used inline. • Excessive use of <div> tags is almost as bad as excessive use of tables, particularly when structuring page content. • The HTML 4 specification specifies that the datafld, dataformatas, and datasrc attributes are reserved for <div> and might be supported in the future. They were removed from XHTML, but Internet Explorer supports them for data binding. • Under the HTML 4.01 strict specification, the align attribute is not supported. • HTML 3.2 supports only the align attribute. <dl> (Definition List) This element encloses a list of terms and definitions.

However, there is no requirement to match these elements, alternate them, or anything else, at least syntax-wise. • Some page designers might use a <dl> tag or <ul> tag to create text indention. Although this is a common practice on the Web, it is not advisable because it confuses the meaning of the element by making it a physical layout device rather than a list. A CSS property like margin or position should be used instead. Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark.
