Crear div flotante usando CSS y Bootstrap: 3 ejemplos

Veremos 3 ejemplos para que un Div te sigue con el scroll

Crear div flotante usando CSS y Bootstrap. En este artículo veremos cómo crear un DIV flotante y que nos siga si bajamos con el SCROLL, es decir un div que nos sigue con el scroll y mostraremos 3 ejemplos completos.

¿Para qué me sirva crear div flotante?

Si tienes páginas con bastante contenido y generándose scroll en la pantalla del navegador puede ser interesante mantener visible un DIV para mostrar un menú o buscador web.

Mostrar un anuncio publicitario o promociones. (¡aprovecha este Black Friday con ofertas imperdibles!) si es que vendemos algún producto.

Los usos son variados y dependerá de la necesidad del desarrollador o la empresa.

Ventajas de aplicar esta técnica de crear div flotante

  • Ventas. – Si tu sitio es un Ecommerce, obviamente estas poniendo el producto delante de un potencial cliente y se reflejara en ventas.
  • Publicidad. – Aunque suele ser molestoso la publicidad, también podemos colocar un anuncio en un DIV fijo lo que lograra será más conversiones.
  • Opciones. – Si es un sistema web, estarías mostrando al usuario final las opciones de configuración siempre a la mano, por ejemplo, el botón “Guardar registro” o “Editar registros“.
  • Navegación. – Ayuda a la navegación porque las opciones siempre serán visibles, como ser por ejemplo el correo “GMAIL” a pesar que bajamos el scroll las opciones del lado izquierdo siempre están visibles.

La solución es: Crear div flotante

A continuación, veremos 3 formas para crear DIV flotantes en nuestro sitio web o sistema web.

Usando estilos CSS

Para darle solución a este problema puedes utilizar el atributo position de CSS en el contenedor que queremos tener siempre visible, ejemplo:

position: fixed;

Para tenerlo más ordenado podemos crear una clase CSS llamado “div-fixed” que sería una clase personalizada por el programador.

El código CSS que necesitamos para fijar una determinada etiqueta es el siguiente:

.div-fixed {
position: fixed;
min-height: 120px;
text-align: center;
word-wrap: break-word;
width: 252px;
}

Si observa domos la clase anterior hemos aplicado propiedades y valores que significa lo siguiente:

  • Se declaró una posición fija.
  • Establecemos una altura mínima de 120px.
  • Un ancho de 252px.
  • El texto centrado.
  • Evitamos que el texto se salga del contenedor.

Luego, dentro de las etiquetas <body> tenemos nuestro código HTML:

<div class="div-fixed bg-warning">
<p>Div izquierda que esta fijo...</p>
<p><a class="btn btn-primary" href="index-con-bootstrap.html">Ver ejemplo con Bootstrap</a></p>
</div>

Usando Framework BootStrap

Si usas Bootstrap 5 en tu sitio o sistema web, podemos conseguir un resultado mucho más sencillo y preciso. Por lo tanto, solo tienes que añadir la clase «position-fixed» al DIV que quieres fijar, por ejemplo:

<div class="position-fixed">
Columna izquierda que se mueve con el scroll...
</div>

La clase “position-fixed” viene predefinido con el framework Bootstrap y podemos usarlo en nuestros proyectos, dando resultados muy eficaces.

Conclusión

La implementación de un DIV fijo es muy sencillo y en este artículo hemos realizado 3 ejemplos completos. Además, hemos visto que se pueden realizar usando CSS o usando el Framework Boostrap5.

Además, a estos DIV flotantes se pueden agregar conexión a base de datos y usando el ciclo foreach para mostrar información de BD.

Sin duda esta implementación es requerida por grades compañías porque dan muy buenos resultados en varios ámbitos. Sin embargo, tienes sus ventajas y debemos de aprovecharlo al máximo.

Les dejare el link de descarga del script con los tres ejemplos.
