Hi cfnet21,
I think you should not hide this feedback, you can add the following CSS code to Tools > Custom CSS.
.contact label.invalid {
width: 100%;
text-align: left;
}
.form-control-feedback {
width: 100%;
text-align: right;
}
However, if you hide this feedback, you can use the following CSS Code:
.form-control-feedback {
display: none;
}
