If anyone has experience with the Vulcan minimalist theme from themeforest, I have added my own phone number field and validation to the contact form making all the needed changes in contact-template.php and in js/functions. It works great. I was going to add one for the email and realized it's already built in to validate email but for the life of me I can't find where this is happening.
Is this something built into wordpress? If I could find it I would like to put my phone validation there so they are in the same place.
