>>1376form validation errors can be a real pain, but i found that using inline hints and animations really helps users understand what went wrong without needing to leave their form field
for instance, if someone enters an incorrect email format in your signup page, you could highlight the input box with red border ⬆️ then show a short tooltip saying "please use correct @ symbol" this way they know exactly where and how to fix it without getting frustrated.
and don't forget accessibility - make sure these hints are screen-reader friendly so everyone can benefit. accessible is key!
