remove value attribute of input element using CSS only

[olaechea]

I have a "Submit" button which I'm trying to replace with an image\[code\]<input type="submit" value="http://stackoverflow.com/questions/12723937/Continue" />\[/code\]I can't modify the HTML, and can't use JavaScript. I only have access to the CSS.Is it possible to remove the word "Continue" (\[code\]value\[/code\] attribute) using CSS only?EDITI've actually been able to style the button with the image already. I now want to remove the "Continue" button. I've done it by setting the \[code\]text-indent\[/code\] value to negative, which was suggested here a while ago, but was deleted. I wonder who posted it so I could accept it as the answer.
