En este art\u00edculo puedes encontrar la informaci\u00f3n que necesitas para a\u00f1adir im\u00e1genes adaptable a todos los dispositivos utilizando el framework Bootstrap 4<\/strong>.<\/p>\n

Documentaci\u00f3n y ejemplos para convertir las im\u00e1genes en dise\u00f1o responsivo (para que nunca se vuelvan m\u00e1s grande que sus contenedores). Todo sin romperte mucho la cabeza. Tan solo agregando estilos a trav\u00e9s de clases CSS. Bootstrap<\/strong> ya lo tiene preparado para usar y hacerte la vida m\u00e1s f\u00e1cil.<\/p>\n

Con Bootstrap<\/strong> las im\u00e1genes responsivas se pueden conseguir f\u00e1cilmente agregando a la imagen el atributo \u00abclass\u00bb con el valor \u00abimg-fluid\u00bb. As\u00ed de simple.<\/p>\n

Las im\u00e1genes en Bootstrap<\/strong> se adaptan a todos los dispositivos con .img-fluid que agrega un ancho m\u00e1ximo del 100% y una altura autom\u00e1tica. Se aplica a la clase de la imagen para que se escale con el contenedor padre.<\/p>\n

Por ejemplo:<\/p>\n

<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
<img<\/span><\/a> class<\/span>=<\/span>"img-fluid"<\/span> src<\/span>=<\/span>"https:\/\/picsum.photos\/id\/237\/1500\/600"<\/span> \/<\/span>><\/span><\/pre><\/div><\/div>\n
En el ejemplo en funcionamiento estamos trabajando con una imagen relativamente grande. Tiene un tama\u00f1o de 1500px de ancho y 600px de alto. Si lo agregamos de la siguiente forma:<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
<div<\/span><\/a> class<\/span>=<\/span>"row"<\/span>><\/span>\n    <div<\/span><\/a> class<\/span>=<\/span>"col-lg-12"<\/span>><\/span>\n        <img<\/span><\/a> class<\/span>=<\/span>"img-fluid"<\/span> src<\/span>=<\/span>"https:\/\/picsum.photos\/id\/237\/1500\/600"<\/span> \/<\/span>><\/span>\n    <\/<\/span>div<\/span><\/a>><\/span>\n<\/<\/span>div<\/span><\/a>><\/span><\/pre><\/div><\/div>\n
La imagen se adaptar\u00e1 al tama\u00f1o del contenedor padre tal y como describimos anteriormente.<\/p>\n
De esta forma, se adaptar\u00e1 perfectamente a todos los dispositivos.<\/p>\n
Alinear las im\u00e1genes con las clases flotantes o de alineaci\u00f3n de texto tambi\u00e9n es posible. Las im\u00e1genes a nivel de bloque pueden centrarse utilizando la clase de utilidad de margen .mx-auto.<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
<img<\/span><\/a> class<\/span>=<\/span>"rounded mx-auto d-block"<\/span> src<\/span>=<\/span>"https:\/\/picsum.photos\/id\/237\/200\/200"<\/span> \/<\/span>><\/span><\/pre><\/div><\/div>\n
Ahora, tenemos una imagen peque\u00f1a de 200px que hemos centrado con \u00abmx-auto\u00bb. La clase \u00abrounded\u00bb es un detalle para poner borde redondeado a la imagen. La clase \u00abd-block\u00bb se utiliza para controlar la estructura. Con ella estamos definiendo que la imagen es un bloque. De esta forma, se har\u00e1 autom\u00e1ticamente un salto de l\u00ednea.<\/p>\n
Las im\u00e1genes pueden adoptar comportamientos flotantes. Bootstrap<\/strong> tiene disponible 2 clases que permite flotar los elementos a la izquierda o derecha.<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
<div<\/span><\/a> class<\/span>=<\/span>"row"<\/span>><\/span>\n    <div<\/span><\/a> class<\/span>=<\/span>"col-lg-12"<\/span>><\/span>\n        <img<\/span><\/a> class<\/span>=<\/span>"rounded float-left"<\/span> src<\/span>=<\/span>"https:\/\/picsum.photos\/id\/237\/200\/200"<\/span> \/<\/span>><\/span>\n        <img<\/span><\/a> class<\/span>=<\/span>"rounded float-right"<\/span> src<\/span>=<\/span>"https:\/\/picsum.photos\/id\/237\/200\/200"<\/span> \/<\/span>><\/span>\n    <\/<\/span>div<\/span><\/a>><\/span>\n<\/<\/span>div<\/span><\/a>><\/span><\/pre><\/div><\/div>\n
La clase \u00abfloat-left\u00bb posiciona el elemento o caja lo m\u00e1s posible a la izquierda de su posici\u00f3n original y la clase \u00abfloat-right\u00bb lo mismo pero a la derecha.<\/p>\n
