problem with clicking the input fields

I would love to see this as well.

This might help if you want to do it with jQuery:

(note I haven’t actually tried this and it might not work with the gravity forms placeholder jquery)

You can also do it with CSS in non-ancient browsers:

/* WebKit < 19 */
input:focus::-webkit-input-placeholder { color: transparent; }
/* Firefox < 19 */
input:focus:-moz-placeholder { color: transparent; }
/* Firefox > 19 */
input:focus::-moz-placeholder { color: transparent; }
/* Internet Explorer 10 */
input:focus:-ms-input-placeholder { color: transparent; }
