Se puede especificar una imagen de fondo para casi cualquier elemento HTML<\/strong>. Para agregar una imagen de fondo en un elemento HTML<\/strong>, usa el atributo HTML style<\/em><\/strong> y la propiedad de background-image<\/em><\/strong> de CSS<\/strong>.<\/p>\n\n\n\n

Ejm<\/strong><\/p>\n\n\n\n

<p style=\"background-image: url('img_girl.jpg');\"><\/pre>\n\n\n\n
Tambi\u00e9n puedes especificar la imagen de fondo en el elemento <style><\/em><\/strong>, en la secci\u00f3n <head><\/em><\/strong>.<\/p>\n\n\n\n
Ejm<\/strong><\/p>\n\n\n\n
<style>\np {\n  background-image: url('img_girl.jpg');\n}\n<\/style><\/pre>\n\n\n\n
Imagen de fondo en una p\u00e1gina<\/h2>\n\n\n\n
Si deseas que toda la p\u00e1gina tenga una imagen de fondo, debes especificar la imagen de fondo en el elemento <body><\/em><\/strong>.<\/p>\n\n\n\n
Ejm<\/strong><\/p>\n\n\n\n
<style>\nbody {\n  background-image: url('img_girl.jpg');\n}\n<\/style><\/pre>\n\n\n\n
Background repeat<\/h2>\n\n\n\n
Si la imagen de fondo es m\u00e1s peque\u00f1a que el elemento, la imagen se repetir\u00e1, horizontal y verticalmente, hasta llegar al final del elemento:<\/p>\n\n\n\n
Ejm<\/strong><\/p>\n\n\n\n
<style>\nbody {\n  background-image: url('example_img_girl.jpg');\n  background-repeat: no-repeat;\n}\n<\/style><\/pre>\n\n\n\n
Portada de fondo<\/h2>\n\n\n\n
Si deseas que la imagen de fondo cubra todo el elemento, puedes configurar la propiedad background-size<\/em><\/strong> para que cubra. Adem\u00e1s, para asegurarte de que todo el elemento est\u00e9 siempre cubierto, establece la propiedad background-attachment<\/em><\/strong> en fixed<\/em><\/strong>. De esta forma, la imagen de fondo cubrir\u00e1 todo el elemento, sin estirarse (la imagen mantendr\u00e1 sus proporciones originales).<\/p>\n\n\n\n
Ejm<\/strong><\/p>\n\n\n\n
<style>\nbody {\n  background-image: url('img_girl.jpg');\n  background-repeat: no-repeat;\n  background-attachment: fixed;\n  background-size: cover;\n}\n<\/style><\/pre>\n\n\n\n
Background stretch (estiramiento de fondo)<\/h2>\n\n\n\n
Si deseas que la imagen de fondo se estire para adaptarse a todo el elemento, puedes establecer la propiedad background-size<\/em><\/strong> en 100 % 100 %:<\/p>\n\n\n\n
