Ordered List
Unordered list has each item has a sequential leading symbol. The browser assigns this sequence automatically. The Ordered list is created using <ol>..</ol> block and the item in the list use the <li> element. The browser inserts an extra line before the list and indents the list a few spaces to the right. <ol> Header of unordered list <li> 1st list item <li> 2nd list item <li> 3rd list item <ol> The each item in the list is displayed as leading symbol. The symbol can be - 1 (Arabic numerals: 1, 2,3..) - a (Lowercase letters: a, b, c.. etc.) - A (Uppercase letters: A, B, C.. etc.) - i (Lowercase Roman Numerals: i, ii, iii.. etc.) - I (Uppercase Roman Numerals: I, II, III.. etc.)
Attributes of Ordered List
The symbol appearance can be changed using the type attribute and start attribute.

Definition Lists
A definition list is a sequence of terms and descriptions of these terms. The definition list are created using the <dl>..</dl> block. Inside <dl> element the following elements are inserted. <dt> tag - Definition term <dd> tag - Definition description Definition lists are rendered differently on different browsers. All terms and descriptions are rendered on a new line. More than one terms and more than one description are included in the definition list.
Attributes of definition list
compact - A definitoin list can be rendered compactly if the compact(remove spaces) attribute is added to <dl> element. When the compact attribute is added the description starts on the same line as the associated term.
