mirage_dread 0 Posted March 30 Report Share Posted March 30 I have been looking into log in forms and i was looking at the how to "https://www.w3schools.com/howto/howto_css_login_form.asp" and i was curious how when a password or a username is not enter the grey box appears saying "Please fill in the field" and i was wondering what code is respondable for this? If anyone cause help me with this i'll be grateful. Quote Link to post Share on other sites
