{{ CSSRef() }}

The CSS repeating-linear-gradient function creates an {{ xref_cssimage() }} of a repeating gradients. It works similarly, and takes the same arguments, to the basic linear gradients, as described by {{ cssxref("linear-gradient") }}, but it automatically repeats the color stops infinitely in both directions, with their positions shifted by multiples of the difference between the last color stop's position and the first one's position.

The consequence is that an end color of a gradient always coincide with a start color. If both are not identical, this will result in a sharp transition.

Like any other gradient, a repeating CSS linear gradient is not a CSS <color> but an image with no intrinsic dimensions; that is, it has no natural or preferred size, nor ratio. Its concrete size will match the one of the element it applies to.

Mozilla currently only supports CSS gradients as values of the {{ Cssxref("background-image") }} property, as well as within the shorthand {{ Cssxref("background") }}. You specify a gradient value instead of an image URL.

Syntax

 

Formal grammar: repeating-linear-gradient(  [ <angle> | to <side-or-corner> ,]? <color-stop> [, <color-stop>]+ )
                                            \---------------------------------/ \----------------------------/
                                              Definition of the gradient line         List of color stops  

                              where <side-or-corner> = [left | right] || [top | bottom]
                                and <color-stop>     = <color> [ <percentage> | <length> ]?
repeating-linear-gradient( 45deg, blue, red );           /* A repeating gradient on 45deg axe starting blue and finishing red */
repeating-linear-gradient( to left top, blue, red);      /* A repeating gradient going from the bottom right to the top left 
                                                            starting blue and finishing red */

repeatinglinear-gradient( 0deg, blue, green 40%, red );  /* A repeating gradient going from the bottom to top, starting blue, being green after 
                                                            40% and finishing red */ 

Values

<side-or-corner>
Represents the position of the starting-point of the gradient line. It consists of two keywords: the first one indicates the horizontal side, left or right, and the second one the vertical side, top or bottom. The order is not relevant and each of the keyword is optional.
The values to top, to bottom, to left and to right are translated into the angles 0deg, 180deg, 270deg, 90deg respectively. The others are translated into an angle that let the starting-point to be in the same quadrant than the described corner and so that the line defined by the starting-point and the corner is perpendicular to the gradient line. That way, the color described by the <color-stop> will exactly apply to the corner point. This is sometimes called the "magic corner" property. The end-point of the gradient line is the symmetrical point of the starting-point on the other direction of the center box.
<angle>
An angle of direction for the gradient. See {{ Xref_cssangle() }}.
<color-stop>
This value is comprised of a {{ Xref_csscolorvalue() }} value, followed by an optional stop position (either a percentage between 0% and 100% or a {{ Xref_csslength() }} along the gradient axis).
Rendering of color-stops in CSS gradients follows the same rules as color-stops in SVG gradients.

Example

background: repeating-linear-gradient(to bottom right, red, red 5px, white 5px, white 10px);

[1] Internet Explorer 5.5 through 8.0 supports proprietary filter: progid:DXImageTransform.Microsoft.Gradient() filter.

[2] Firefox 3.6 implemented, prefixed, an early syntax where the starting corner or side was indicated without the to keyword, and effectively considered as a from position. The to syntax has been added in Firefox 10, without removing the deprecated syntax and translation between the two is trivial:

-moz-repeating-linear-gradient(to top left, blue, red);

is the same as:

-moz-repeating-linear-gradient(bottom right, blue, red);

The legacy syntax, without to, is planned to go away when the prefix will be removed.

 

[3] Gecko, Opera & Webkit considers {{ xref_cssangle("") }} to start to the right, instead of the top. I.e. it considered an angle of 0deg as a direction indicator pointing to the right. This is different from the latest specification where an angle of 0deg as a direction indicator points to the top.
