Las propiedades de fondo (en ingl\u00e9s background) en CSS<\/strong>, nos permiten controlar el color de fondo o parte trasera de un elemento.<\/p>\n

Establecer un color o una imagen de fondo, la ubicaci\u00f3n de la misma dentro del fondo (centrada, a la izquierda, en alguna coordenada de x,y, etc.) y la cantidad de veces que se va a repetir son algunas de las muchas propiedades que se pueden aplicar a los fondos con CSS<\/strong>.<\/p>\n

En el ejemplo en funcionamiento te lo estar\u00e9 ilustrando trabajando con el elemento <body> pero la propiedad fondo las puedes aplicar sobre cualquier elemento de la p\u00e1gina.<\/p>\n

Color de fondo<\/h2>\n

Si lo que deseas es aplicar un color de fondo a un elemento tan solo tienes que aplicarlo as\u00ed:<\/p>\n

<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
body {<\/span>\n    background-color<\/span>:<\/span> red<\/span>;<\/span>\n}<\/span><\/pre><\/div><\/div>\n
En este caso, le aplico un color rojo haciendo uso de los colores preestablecidos<\/strong>.<\/p>\n
Si quisieras dar un color de fondo m\u00e1s personalizado, deber\u00e1s usar los colores en formato hexadecimal<\/strong>, como por ejemplo:<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
body {<\/span>\n    background-color<\/span>:<\/span> #e85131<\/span>;<\/span>\n}<\/span><\/pre><\/div><\/div>\n
De esta forma, puedes aplicar un color o tono rojo m\u00e1s exacto al que necesitas.<\/p>\n
Tambi\u00e9n se puede aplicar un color de fondo usando el c\u00f3digo RGB de la siguiente forma:<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
body {<\/span>\n    background-color<\/span>:<\/span>rgb<\/span>(<\/span>255,<\/span> 0,<\/span> 0)<\/span>;<\/span>\n}<\/span><\/pre><\/div><\/div>\n
Para indicar que el cuerpo de la p\u00e1gina tendr\u00e1 un color rojo tambi\u00e9n.<\/p>\n
Imagen de fondo<\/h2>\n
A los elementos tambi\u00e9n se le puede establecer una imagen de fondo.<\/p>\n
En este caso, lo podemos hacer as\u00ed:<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
body {<\/span>\n    background-image<\/span>:<\/span> url<\/span>(<\/span>'..\/images\/fondo.jpg'<\/span>)<\/span>;<\/span>\n}<\/span><\/pre><\/div><\/div>\n
En Google puedes buscar las palabras clave \u00abpattern background\u00bb y puedes encontrar miles de fondos que puedes usar para tus p\u00e1ginas webs.<\/p>\n
Tambi\u00e9n se que existen p\u00e1ginas que te ofrecen bancos de im\u00e1genes en las que puedes encontrar fondos muy interesantes.<\/p>\n
