Aquí tienes tres estilos completamente diferentes para tus enlaces (<a>), listos para usar. Van desde lo más minimalista hasta un efecto moderno con animaciones CSS.

Puedes elegir el que mejor se adapte al diseño de tu sistema:

Opción 1: Línea animada (Efecto Minimalista y Moderno)
Este estilo no tiene la molesta línea subrayada estática de siempre. En su lugar, cuando pasas el mouse por encima (hover), aparece una línea suave que se expande desde el centro hacia los lados.

CSS
.link-animado {
    color: #3b82f6; /* Azul moderno */
    text-decoration: none;
    position: relative;
    font-weight: 500;
    transition: color 0.3s ease;
}

/* Crear la línea oculta abajo */
.link-animado::after {
    content: '';
    position: absolute;
    width: 100%;
    transform: scaleX(0);
    height: 2px;
    bottom: -2px;
    left: 0;
    background-color: #3b82f6;
    transform-origin: bottom center;
    transition: transform 0.25s ease-out;
}

/* Animación al pasar el mouse */
.link-animado:hover {
    color: #1d4ed8; /* Azul más oscuro */
}

.link-animado:hover::after {
    transform: scaleX(1);
}
