Description
Describing the
input element simply is not straightforward, as there
is much variation in the way an input appears—and the
attributes it uses or requires—depending on the
type attribute specified. But whatever the
type, the feature that’s common to all
input elements is that they allow users to enter
data.
The specific features of each kind of input are covered in the
type attribute
section of this reference. Other type-specific attributes are
indicated as such in their own sections.
Use This For …
The input
element is used to capture user information. The kind of control that’s
used will vary on a case-by-case basis, as explained in type.
