Two elements x and y of L are complements of each other if and only if: x ∨ y = 1 and x ∧ y = 0. In general some elements of a bounded lattice might not have a complement and others might have more than one complement. For example the set {0 ½ 1} with its usual ordering is a bounded lattice and ½ does not have a complement.

In mathematics especially in order theory a maximal element of a subset S of some partially ordered set (poset) is an element of S that is not smaller than any other element in S.A minimal element of a subset S of some partially ordered set is defined dually as an element of S that is not greater than any other element in S.. The notions of maximal and minimal elements are weaker than those …

Each element contains the following : The content of an element is the actual text (or other media) placed between the opening and closing tags of an element . The padding of an element is the space around the content but which still forms part of the element . Padding should not be used to create white space b…
