Popup Login Form Design in HTML & CSS

Popup boxes (or dialog boxes) are modal windows used to inform or alert the user, or to get input from the user. Popup boxes restrict the user from accessing other features of a program until the popup is closed, so they should not be overused.

As you have seen on many websites there is a modal login form that is based on JavaScript or JavaScript library. But today I'll share with you this program (Popup or Modal Login Form) using only HTML & CSS. In this program, at first, on the webpage, there is a white button with "View Form" text. And when you click on that button then the Popup or Modal Login Form will be displayed.

You can copy the codes from the given boxes or download the code files from the given link but I recommend you to download the source code files instead of copying codes. Click here to download code files.

Great tutorial! I appreciate how you broke down each step, making it easy to follow. The explanation of form validation is especially helpful, as it ensures user inputs are correct before submission. Best Preschools in Koramangala. Would love to see more examples like this for other types of elements. Keep up the good work!
