Spellcheck disable with CSS not HTML

Question

I want to disable spellchecking in Chrome/Safari using CSS. In HTML spellcheck=\"false\" works but I want to do this in a way that will affect all input fields.

Answer 1

This does not belong to the realm of CSS (which is optional presentational suggestions). It is not about stylistic features of rendering data but about processing data interactively.

On browsers that support “spell checking” (which may involve grammar and style checks), the HTML attribute spellcheck or the corresponding IDL (DOM) attribute, settable in JavaScript, is effective.

In practice, those browsers tend to have “spelling checking” enabled by default for textareas only, and as textareas normally contain human language texts, turning it off does not sound useful. It is in any case user-controllable (the user can switch it off or select language).
