thanks for the information.
I only need a white border around the text boxes so you can see this better

I could also imagine the transparency to decrease, rather than the white borders
You can do something like the code below to change the opacity of your email field at the link you have provided.
.wpcf7 .wpcf7-form-control.wpcf7-email {
background-color: rgba(255, 255, 255, 0.9);
}
Suggest you go through the link I have provided in my reply above to help you make changes to the other fields.
You may add your CSS via https://wordpress.org/plugins/simple-custom-css/
Yes it worked, would you be kind enough to tell me how I adapt the code to the remaining input fields?
