CSS text forced uppercase input

Text-transform:uppercase;

The Text-transform property controls the case of the text.

This property changes the case of the letters in the element, regardless of the case of the text in the source document. If the value is capitalize, some letters are capitalized, but there is no clear definition of how to determine which letters to capitalize, depending on how the user agent recognizes the individual words.

Possible values

value	Description
None	Default. Defines the standard text with lowercase letters and uppercase letters.
Capitalize	Each word in the text begins with an uppercase letter.
Uppercase	Only uppercase letters are defined.
lowercase	Defines no capital letters, only lowercase letters.
Inherit	Specifies that the value of the Text-transform property should be inherited from the parent element.
