The id attribute, short for identity, defines a unique name for an element.
Using an id lets you find that element easily in code and apply styles.
During export every element is given a unique id. If two elements have the same default id a new one is created. Ids must be unique per page.
View the messages that are created during export to see any notifications of duplicate ids.
When you define your own id you can refer to it in code and stylesheets.
Set the id to
none to exclude the id attribute.
