CSS Gradient

Two types of gradients:

Linear Gradients (goes down/up/left/right/diagonally)
Radial Gradients (defined by their center)

CSS Linear Gradients:

To create a linear gradient you must provide at least two (or more) color stops.

Syntax:

background-image: linear-gradient(direction, color-stop1, color-stop2, ...);

Top to Bottom:

<!DOCTYPE html>
<html>
<head>
<style>
#grad1 {
 height: 200px;
 background-color: red; /* For browsers that do not support gradients */
 background-image: linear-gradient(red, yellow);
}
</style>
</head>
<body>

<h1>Linear Gradient - Top to Bottom</h1>

<div id="grad1"></div>

</body>
</html>

OUTPUT:

Left to Right:

<!DOCTYPE html>
<html>
<head>
<style>
#grad1 {
 height: 200px;
 background-color: red; /* For browsers that do not support gradients */
 background-image: linear-gradient(to right, red , yellow);
}
</style>
</head>
<body>

<h1>Linear Gradient - Left to Right</h1>

<div id="grad1"></div>

</body>
</html>

OUTPUT:

Using Angles:

Create an angle, instead of the predefined directions (to bottom, to top, to right, to left, to bottom right, etc.).

Syntax:

background-image: linear-gradient(angle, color-stop1, color-stop2);

Example:

<!DOCTYPE html>
<html>
<head>
<style>

#grad2 {
 height: 100px;
 background-color: red; /* For browsers that do not support gradients */
 background-image: linear-gradient(90deg, red, yellow);
}

#grad3 {
 height: 100px;
 background-color: red; /* For browsers that do not support gradients */
 background-image: linear-gradient(180deg, red, yellow);
}

#grad4 {
 height: 100px;
 background-color: red; /* For browsers that do not support gradients */
 background-image: linear-gradient(-90deg, red, yellow);
}
</style>
</head>
<body>

<h1>Linear Gradients - Using Different Angles</h1>
<div id="grad2" style="text-align:center;">90deg</div><br>
<div id="grad3" style="text-align:center;">180deg</div><br>
<div id="grad4" style="text-align:center;">-90deg</div>

</body>
</html>

OUTPUT:

Using Multiple Color Stops:

<!DOCTYPE html>
<html>
<head>
<style>

#grad2 {
  height: 200px;
  background-color: red; /* For browsers that do not support gradients */
  background-image: linear-gradient(red, orange, yellow, green, blue, indigo, violet);
}

</style>
</head>
<body>
<h1>Linear Gradients - Multiple Color Stops</h1>
<h2>7 Color Stops (evenly spaced):</h2>
<div id="grad2"></div>
</body>
</html>

OUTPUT:

Using Transparency:

Which can be used to create fading effects.

Example:

<!DOCTYPE html>
<html>
<head>
<style>
#grad1 {
 height: 200px;
 background-image: linear-gradient(to right, rgba(255,0,0,0), rgba(255,0,0,1));
}
</style>
</head>
<body>

<h1>Linear Gradient - Transparency</h1>
<div id="grad1"></div>

</body>
</html>

OUTPUT:
