Thanks for the response, it's on acuity I'm not sure how to do password protect but here's the site. https://driptbooking.as.me/schedule.php# the fields are so narrow.
They have good documentation on how to edit other css items except for the fields. https://developers.acuityscheduling.com/docs/css-customization
I just got the paid tier where you can customize acuity with CSS, but for some reason I can't find documentation on how to make the input fields a bit larger, and change the borders.
Its the Name, Phone, and Email fields.
