I have a contact form and I would like to change the color of placeholder to white. I tried adding classes via CSS, but I have failed.
<input type="text" name="FullName" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-validates-as-required cnt_inp1" aria-required="true" aria-invalid="false" placeholder="Full Name*">
If somebody could explain me and give me the solution, that would be great.
Thanks in advance.
