Animated Glowing Login Form in Html and CSS

project demo

Introduction:

Happy coding to all the amazing coders out there! 👋 Today we’re going to create a glowing animated login form in HTML and CSS. This form will have a smooth gradient border that glows beautifully when hovered, giving it a modern and eye-catching look. The background will be dark to make the neon colors pop, and the input fields will have a clean, minimal design. It will also include options like “Forgot Password?” and “Sign up,” making it look just like a real login interface.

HTML:

In Html code, we have a main container that holds everything in the center of the screen. Inside this container, there’s a box that creates the glowing effect and holds the login form. The inner-box works as a transparent layer that gives the glassy background style. Inside it, we have a form section that contains the heading “Login” along with input fields for username and password. There’s also a submit button that says “Sign in” to log in. At the bottom, a small section includes links for “Forgot Password?” and “Sign up” options.

CSS:

In the CSS, we first reset all default margins and paddings and apply the Poppins font for a clean look. The body is styled with a dark background and centered layout using flexbox. The container and box create the main structure, with the box having a glowing gradient border that animates smoothly on hover. The ::before and ::after pseudo-elements add the neon gradient and blur effects to make the box glow beautifully. The inner-box adds a glass-like transparent layer with shadows and borders for depth. The form is centered inside with neatly spaced input fields and a stylish heading. Input fields are given rounded corners and a subtle dark background to match the theme. Lastly, the submit button has a colorful gradient and hover glow, while the bottom links are styled to stand out clearly.
