background-image

웹 문서에 이미지를 표현하는 방법은 두가지가 있습니다. img 태그와 background 속성을 이용하는 방법입니다. 원칙적으로 의미가 있는 이미지는 img 태그를 사용하고, 그렇지 않은 경우는 background 속성을 사용합니다. background 속성은 의미가 없는 이미지를 사용하기 위한 방법입니다. 배경이 장식용이거나 디자인 용도라면 background를 이용해서 많이 사용합니다. 여기에는 사이즈, 반복여부, 위치, 효과 등 다양한 속성을 사용할 수 있습니다.

정의(Definition)

background-image 속성은 배경 이미지 경로 및 그라디언트를 설정합니다.
background-image 속성은 다중 이미지를 익스플로러9 이상부터 지원됩니다.

문법(Syntax)

background-image : none | url | gradient

/* 기본 속성 */
background-image : none;
background-image : url("../image.jpg");

/* 다중 이미지 설정 */
background-image : url("../image1.jpg"), url("../image2.jpg");

/* 그라디언트 설정 */
background-image : linear-gradient();
background-image : radial-gradient();
background-image : repeating-linear-gradient();
background-image : repeating-radial-gradient();

/* 전역 속성 */
background-image : inherit;   /* 상속 */
background-image : initial;   /* 초기화 */
background-image : revert;    /* 원래대로 돌리기 */
background-image : unset;     /* 설정 해제 */

속성(Property)

속성값	값(예)	설명
none	background-image : none;	백그라운드 이미지를 설정하지 않습니다.
url	background-image : url(../img.jpg);	백그라운드 이미지 경로를 설정합니다.
gradient	background-image : radial-gradient();	백그라운에 그라디언트를 설정합니다.
