1. CSS Gradients

2. What is Gradients
• gradients let you display smooth transitions between two or more
specified colors
• using CSS gradients you can reduce download time and bandwidth
usage. In addition, elements with gradients look better when zoomed,
because the gradient is generated by the browser

3. Linear Gradients
• Syntax
background: linear-gradient(direction, color-stop1, color-stop2, ...)

4. Example
• For:
#grad {
height: 200px;
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(red, yellow); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(red, yellow); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(red, yellow); /* For Firefox 3.6 to 15 */
background: linear-gradient(red, yellow); /* Standard syntax (must be last) */
}

5. Gradient with angles
Syntax:
background: linear-gradient(angle, color-stop1, color-stop2);

6. Example
• For:
#grad {
height: 100px;
background: red; /* For browsers that do not support gradients */
background: -webkit-linear-gradient(90deg, red, yellow); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(90deg, red, yellow); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(90deg, red, yellow); /* For Firefox 3.6 to 15 */
background: linear-gradient(90deg, red, yellow); /* Standard syntax (must be last) */
}

7. Multiple Colors
• You can use the syntax
background: linear-gradient(direction, color, color, color ...);
without the direction it will go from top to bottom but it can be from
left to right or right to left.
Also you can put a percent next to the color to make the spacing.

8. Example
• For
#grad {
height: 200px;
background: -webkit-linear-gradient(red 10%, green 85%, blue 90%); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(red 10%, green 85%, blue 90%); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(red 10%, green 85%, blue 90%); /* For Firefox 3.6 to 15 */
background: linear-gradient(red 10%, green 85%, blue 90%); /* Standard syntax (must be last) */
}

9. Transparency
To add transparency, we use the rgba() function to define the color
stops. The last parameter in the rgba() function can be a value from 0
to 1, and it defines the transparency of the color: 0 indicates full
transparency, 1 indicates full color (no transparency).

10. Example
For:
#grad1 {
height: 200px;
background: -webkit-linear-gradient(left, rgba(255,0,0,0), rgba(255,0,0,1)); /* For Safari 5.1 to 6.0 */
background: -o-linear-gradient(right, rgba(255,0,0,0), rgba(255,0,0,1)); /* For Opera 11.1 to 12.0 */
background: -moz-linear-gradient(right, rgba(255,0,0,0), rgba(255,0,0,1)); /* For Firefox 3.6 to 15 */
background: linear-gradient(to right, rgba(255,0,0,0), rgba(255,0,0,1)); /* Standard syntax (must be last) */
}

11. Repeating gradient
Syntax
background: repeating-linear-gradient(red, yellow 10%, green 20%);

12. Radial Gradients
Syntax:
background: radial-gradient(shape size at position, start-color, ..., last-
color);

13. Example
This is with different spacing:
#grad {
background: red; /* For browsers that do not support gradients */
background: -webkit-radial-gradient(red 5%, yellow 15%, green 60%); /* Safari 5.1-6.0 */
background: -o-radial-gradient(red 5%, yellow 15%, green 60%); /* For Opera 11.6-12.0 */
background: -moz-radial-gradient(red 5%, yellow 15%, green 60%); /* For Firefox 3.6-15 */
background: radial-gradient(red 5%, yellow 15%, green 60%); /* Standard syntax */
}

14. The different radical gradients
The size parameter defines the size of the
gradient. It can take four values:
•closest-side
•farthest-side
•closest-corner
•farthest-corner

15. Repeating Gradient
Syntax
background: repeating-radial-gradient(red, yellow 10%, green 15%);

16. • Conic Gradient [explore time]
A conic gradient is a gradient with color transitions rotated
around a center point. To create a conic gradient you must
define at least two colors
• Syntax
• background-image: conic-gradient([from angle] [at position,] color [degree], color
[degree], …)
