background-color CSS 속성은 요소의 배경 색을 지정합니다.

구문

/* Keyword values */
background-color: red;
background-color: indigo;

/* Hexadecimal value */
background-color: #bbff00;    /* Fully opaque */
background-color: #11ffee00;  /* Fully transparent */
background-color: #11ffeeff;  /* Fully opaque */

/* RGB value */
background-color: rgb(255, 255, 128);        /* Fully opaque */
background-color: rgba(117, 190, 218, 0.5);  /* 50% transparent */

/* HSL value */
background-color: hsl(50, 33%, 25%);         /* Fully opaque */
background-color: hsla(50, 33%, 25%, 0.75);  /* 75% transparent */

/* Special keyword values */
background-color: currentcolor;
background-color: transparent;

/* Global values */
background-color: inherit;
background-color: initial;
background-color: unset;

background-color 속성은 하나의 <color> 값을 사용해 지정합니다.

color
요소의 배경으로 사용할 단일 색상. background-image 뒤에 렌더링 되지만 투명한 부분으로 보일 수 있습니다.
