The Hard state indicates that the text in the textarea is to have newlines added by the user agent so that the text is wrapped when it is submitted.
If the element's wrap attribute is in the Hard state, the cols attribute must be specified.

Notes

Remarks

The default font is fixed pitch.

Firefox for Android, by default, sets a background-image gradient on all textarea elements. This can be disabled using background-image: none.

Safari Mobile for iOS applies a default style of opacity: 0.4 to disabled textarea elements. Other major browsers don't currently share this particular default style.

Security Warning:  Using this object incorrectly can compromise the security of your application. When submitting text through textarea over an intranet or the Internet, validating the text string is recommended. For instance, you might validate the string for a restricted set of known, good values (such as letters and numbers) and ignore the rest.

Default CSS

white-space: pre-wrap;
text-indent: initial;
