background-image

Introduction

The background-image CSS property sets one or more background images on an element.
The background images are drawn on stacking context layers on top of each other. The first layer specified is drawn as if it is closest to the user.
The border of the element are then drawn on top of them, and the background-color is drawn beneath them. How the images are drawn relative to the box and its borders is defined by the background-clip and background-origin CSS properties.

Examples

Syntax

background-image:
  linear-gradient(to bottom, rgba(255, 255, 0, 0.5), rgba(0, 0, 255, 0.5)),
  url('https://lf-lynx.tiktok-cdns.com/obj/lynx-artifacts-oss-sg/lynx-website/assets/doc/catfront.png');

Values

Each background image is specified either as the keyword none or as an <image> value.

none Is a keyword denoting the absence of images.
<image> Is an <image> denoting the image to display. There can be several of them, separated by commas. The supported image formats for background-image are the same as those for image, including jpg, png, gif, webp, etc. Refer to Supported Image Formats

Formal Syntax

background-image = <bg-image>#

<bg-image> = none | <image>

<image> = <url()> | <gradient>

<url()> = url(<string>)

<gradient> = <linear-gradient()> | <radial-gradient()> | <conic-gradient()>

<linear-gradient()> =
  linear-gradient( [ <angle> | to <side-or-corner> ]? , <color-stop-list> )

<radial-gradient()> =
  radial-gradient( [ <ending-shape> || <size> ]? [ at <position> ]? , <color-stop-list> )

<conic-gradient()> =
  conic-gradient( [ from [ <angle> | <zero> ] ]? [ at <position> ]? , <color-stop-list> )

<side-or-corner> =
  [ left | right ] || [ top | bottom ]

<ending-shape> =
  circle | ellipse

<size> =
  closest-side       |
  farthest-side      |
  closest-corner     |
  farthest-corner    |
  <length>           |
  <length-percentage>{2}

<position> =
  [ left | center | right ] || [ top | center | bottom ]                            |
  [ left | center | right | <length-percentage> ]
    [ top | center | bottom | <length-percentage> ]?                                |
  [ [ left | right ] <length-percentage> ] &&
    [ [ top | bottom ] <length-percentage> ]

<color-stop-list> = <linear-color-stop> ( ',' <linear-color-stop> )*

<linear-color-stop> = <color>

<length-percentage> = <length> | <percentage>

Difference between web

<image> Only support <url()> and <gradient>.
<gradient> Support linear-gradient, radial-gradient, and conic-gradient(since version 3.6).
<linear-color-stop> Not support linear-color-hint

Not support color-interpolation-method

Not support <length> value for position
