How could I adjust font and colour on the following pages?

Try with the following code, it works perfectly on Pacific template:

to change the font on the fields use

.field-element {
   font-family: inherit !important;
   background-color: rgba(255, 255, 255, 1)  !important;
}

to change your button

.button.sqs-system-button.sqs-editable-button {
   font-family: your-font-name !important;
}

use inherit if you want the same font you're using on the rest of your website, otherwise just specify it.

Thank you, the font has now changed but the colour is still blue and the font of name and surname is slightly bigger. Is there a way to change it so that it's the same size as the rest?

Also, do you know by any chance how to change to colour of the button to black?
