id property
String
get
id
The id property of the Element interface
represents the element's identifier, reflecting the
id
global attribute.
If the id value is not the empty string, it must be unique in a
document.
The id is often used with Document.getElementById to retrieve a
particular element.
Another common case is to use an element's
ID as a selector
when styling the document with
CSS.
Note: Identifiers are case-sensitive, but you should avoid creating IDs that differ only in the capitalization.
