Turn off Chrome/Safari spell checking by HTML/css

Question

Is there a way for a web developer to turn off Chrome/Safari/WebKit's spellchecking on particular input or textarea elements? I mean either by special tag attribute or a proprietary CSS instruction.

There is a CSS instruction for turning off outlining of inputs so I thought that might also exist. I know how a user can do it.

Or, as a user, can I disable it for some particular domain?

Answer 1

Yes, there is the HTML5 spellcheck attribute.

<textarea spellcheck="false"> or <input type="text" spellcheck="false">

Update: This is now supported in the latest versions of all browsers.

Answer 2

This works in Safari 7.1 and should work also in others:

<input autocomplete="off" autocorrect="off" autocapitalize="off" 
spellcheck="false"/>

Only spellcheck="false" didn't work.

Answer 3

for all elements of a form it is possible and so:

<form spellcheck="false" .. />

Answer 4

Regarding outlining of input tags: don't do it, it's a visual cue for users.

But if you must:

#your-input{outline:none;}
