Layer

In CSS objects can be displayed on top of one another and described as such along the z-axis.

In design programs, such as Adobe Photoshop and Macromedia Flash, objects (visual or audio) can be placed in separate layers to facilitate the design process. For example, it is easier to manage the design of a complex image if its components can be separated into different layers.

There are 3 kind of layers in Flash:

• normal layers: the layers used for most objects and object parts
• motion guide layers: the layer used for the path of an animation
• mask layers: the layer used for hiding objects or some of their part

Link

Link is the short form for "hyperlink". A link "links" documents, or document fragments to one another. When a user activates a link, the document changes to the position indicated by the link. In web pages links were originally underlined to indicate the link. With style sheets a textual link can take on any design features. Images and other objects can also be used as links.

LISTSERV

Listserv is a program that automates electronic mailing lists. Majordomo is one such program. A user typically subscribes to the list, which automatically sends the emails of other users to that user. Listserv is used by special interest groups to post messages to one another. A message is posted to the listserv server, which sends the message to all subscribers. Some listserv's are fully automated, others have a Moderator who decides whether to allow a message to be forwarded to other members.

Locator

The reference to an anchor. A locator is the structure (such as linked text, image or other object) that a user activates to be taken to the anchor location. In HTML the Locator is declared as a value of the href or id attributes of the Anchor ( a ) element. It serves as the Source of the hypertext anchored link. In HTML this value must be exactly the same as the value of the Destination anchor.
