Glowing Animated Login Form

1) What the files are and how to run them

index.html (your HTML document) contains the structure/markup for the login card and pulls in Font Awesome for icons and style.css for all styling. index
style.css contains all visual rules, animations, layout and interactive hover behavior. style

To run: open index.html in a browser (no server required). The page centers a single .box element that houses the glowing login UI.

2) HTML structure (what each element does)

The HTML markup is simple and semantic for a small component: index

<div class="box"> — the outer container that forms the visible card and the animated glowing ring effect (via CSS backgrounds and pseudo-elements).
Inside .box there’s <div class="login"> which acts as the inner panel (it sits inside the glowing shell).
Inside .login is <div class="loginBx"> — the content holder: a heading, two inputs (username/password), a submit input and a .group with two links (“Forgot Password”, “Sign up”).
Font Awesome icons are used inside the <h2> to enhance visual appeal.

The HTML uses simple form-like inputs, but note: there is no <form> element — so the submit input won’t post unless you wrap with <form> and add action/JS.

3) Global CSS and base setup

From style.css: style

@import pulls the “Poppins” font from Google Fonts for consistent typography.
* { margin:0; padding:0; box-sizing:border-box; font-family: "Poppins", sans-serif; } — resets spacing, uses border-box sizing, and sets the font globally so elements size more predictably.
body { display:flex; justify-content:center; align-items:center; min-height:100vh; background:#252432; } — centers .box both vertically and horizontally and uses a dark background which enhances glow effects.
