hi,
sometimes classes are different according to the site we tried to make class selector unique to the user so that's the reason the above code will not work on your site.
according to your site and classes, the code below will work for you:
.tp-parallax-container .contactblock input.form_field.text{
display:block !important;
}
check:

and make a note that you should always make a separate topic on the forum by which it will be helpful to other users too.
for now, i am closing this topic and if you face any problem with the same issue then please make a separate topic we are always there for you.
