Css for gradient effect

linear-gradient()

The linear-gradient() CSS function creates an image consisting of a progressive transition between two or more colors along a straight line. Its result is an object of the data type, which is a special kind of .

Syntax

/* A gradient tilted 45 degrees, starting blue and finishing red */ linear-gradient(45deg, blue, red); /* A gradient going from the bottom right to the top left corner, starting blue and finishing red */ linear-gradient(to left top, blue, red); /* Color stop: A gradient going from the bottom to top, starting blue, turning green at 40% of its length, and finishing red */ linear-gradient(0deg, blue, green 40%, red); /* Color hint: A gradient going from the left to right, starting red, getting to the midpoint color 10% of the way across the length of the gradient, taking the rest of the 90% of the length to change to blue */ linear-gradient(.25turn, red, 10%, blue); /* Multi-position color stop: A gradient tilted 45 degrees, with a red bottom-left half and a blue top-right half, with a hard line where the gradient changes from red to blue */ linear-gradient(45deg, red 0 50%, blue 50% 100%); 

Values

The position of the gradient line’s starting point. If specified, it consists of the word to and up to two keywords: one indicates the horizontal side ( left or right ), and the other the vertical side ( top or bottom ). The order of the side keywords does not matter. If unspecified, it defaults to to bottom .

The values to top , to bottom , to left , and to right are equivalent to the angles 0deg , 180deg , 270deg , and 90deg , respectively. The other values are translated into an angle.

The gradient line’s angle of direction. A value of 0deg is equivalent to to top ; increasing values rotate clockwise from there.

An interpolation hint defining how the gradient progresses between adjacent color stops. The length defines at which point between two color stops the gradient color should reach the midpoint of the color transition. If omitted, the midpoint of the color transition is the midpoint between two color stops.

Note: Rendering of color stops in CSS gradients follows the same rules as color stops in SVG gradients.

Description

As with any gradient, a linear gradient has no intrinsic dimensions; i.e., it has no natural or preferred size, nor a preferred ratio. Its concrete size will match the size of the element it applies to.

To create a linear gradient that repeats to fill its container, use the repeating-linear-gradient() function instead.

Because s belong to the data type, they can only be used where s can be used. For this reason, linear-gradient() won’t work on background-color and other properties that use the data type.

Composition of a linear gradient

A linear gradient is defined by an axis—the gradient line—and two or more color-stop points. Each point on the axis is a distinct color; to create a smooth gradient, the linear-gradient() function draws a series of colored lines perpendicular to the gradient line, each one matching the color of the point where it intersects the gradient line.

The gradient line is defined by the center of the box containing the gradient image and by an angle. The colors of the gradient are determined by two or more points: the starting point, the ending point, and, in between, optional color-stop points.

The starting point is the location on the gradient line where the first color begins. The ending point is the point where the last color ends. Each of these two points is defined by the intersection of the gradient line with a perpendicular line passing from the box corner which is in the same quadrant. The ending point can be understood as the symmetrical point of the starting point. These somewhat complex definitions lead to an interesting effect sometimes called magic corners: the corners nearest to the starting and ending points have the same color as their respective starting or ending points.

Customizing Gradients

By adding more color-stop points on the gradient line, you can create a highly customized transition between multiple colors. A color-stop’s position can be explicitly defined by using a or a . If you don’t specify the location of a color, it is placed halfway between the one that precedes it and the one that follows it. The following two gradients are equivalent.

linear-gradient(red, orange, yellow, green, blue); linear-gradient(red 0%, orange 25%, yellow 50%, green 75%, blue 100%); 

By default, colors transition smoothly from the color at one color-stop to the color at the subsequent color-stop, with the midpoint between the colors being the halfway point between the color transition. You can move this midpoint to any position between two color-stops by adding an unlabelled % color hint between the two colors to indicate where the middle of the color transition should be. The following example is solid red from the start to the 10% mark and solid blue from 90% to the end. Between 10% and 90% the color transitions from red to blue, however, the midpoint of the transition is at the 30% mark rather than 50% as would have happened without the 30% color hint.

linear-gradient(red 10%, 30%, blue 90%); 

If two or more color-stops are at the same location, the transition will be a hard line between the first and last colors declared at that location.

Color-stops should be listed in ascending order. Subsequent color-stops of lower value will override the value of the previous color-stop creating a hard transition. The following changes from red to yellow at the 40% mark, and then transitions from yellow to blue over 25% of the gradient:

linear-gradient(red 40%, yellow 30%, blue 65%); 

Multi-position color-stops are allowed. A color can be declared as two adjacent color-stops by including both positions in the CSS declaration. The following three gradients are equivalent:

linear-gradient(red 0%, orange 10%, orange 30%, yellow 50%, yellow 70%, green 90%, green 100%); linear-gradient(red, orange 10% 30%, yellow 50% 70%, green 90%); linear-gradient(red 0%, orange 10% 30%, yellow 50% 70%, green 90% 100%); 

By default, if there is no color with a 0% stop, the first color declared will be at that point. Similarly, the last color will continue to the 100% mark, or be at the 100% mark if no length has been declared on that last stop.

Examples

Gradient at a 45-degree angle

body  width: 100vw; height: 100vh; > 

body  background: linear-gradient(45deg, red, blue); > 

Gradient that starts at 60% of the gradient line

body  width: 100vw; height: 100vh; > 

body  background: linear-gradient(135deg, orange 60%, cyan); > 

Gradient with multi-position color-stops

This example uses multi-position color-stops, with adjacent colors having the same color-stop value, creating a striped effect.

body  width: 100vw; height: 100vh; > 

body  background: linear-gradient( to right, red 20%, orange 20% 40%, yellow 40% 60%, green 60% 80%, blue 80% ); >

Scrolling Gradient

I decided to adapt the CSS Only Scroll Indicator technique to make a background gradient that canges with scroll position. The top right corner of the gradient changes while the bottom right remains the same. This works by overlaying 2 gradients, The first is a top-to-bottom gradient with a height of the content. This contains the colors you want to cycle through. The other is a top-left, to bottom-right gradient from transparent to a solid color. This gradient is fixed to the viewport dimensions and pulled behind text, similar to the scroll indicator.
