​
Overview

The ITV Gestion Concesionario application uses a modern glassmorphism design with customizable CSS variables, gradient colors, and responsive layouts. All styling is contained in source/css/styles.css.

​
Primary Color Scheme

The application uses a beautiful gradient color scheme throughout: 
/* Main body gradient background */
body {
    background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
}

/* Header gradient */
.header {
    background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
}

/* Primary button gradient */
.btn-primary {
    background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
}
The primary gradient colors are #667eea (purple-blue) to #764ba2 (purple). These colors are used consistently across the header, buttons, and accent elements.

​
Customizing the Color Palette

To change the main color scheme, update these gradient values in styles.css:

​
Example: Change to Green Theme

/* Replace the gradient values */
body {
    background: linear-gradient(135deg, #10b981 0%, #059669 100%);
}

.header {
    background: linear-gradient(135deg, #10b981 0%, #059669 100%);
}

.btn-primary {
    background: linear-gradient(135deg, #10b981 0%, #059669 100%);
}

​
Glassmorphism Container

The main container uses a glassmorphism effect with backdrop blur: 
.container {
    max-width: 1200px;
    margin: 2rem auto;
    padding: 2rem;
    background: rgba(255, 255, 255, 0.95);
    backdrop-filter: blur(10px);
    border-radius: 0.75rem;
    box-shadow: 0 10px 15px -3px rgb(0 0 0 / 0.1), 
                0 4px 6px -4px rgb(0 0 0 / 0.1), 
                0 0 0 1px rgba(255, 255, 255, 0.1);
    border: 1px solid rgba(255, 255, 255, 0.2);
}
backdrop-filter: blur(10px) creates the frosted glass effect. Adjust the blur value to increase or decrease the effect.

    border-radius: 0.75rem;
