CSS HSL Colors
Cascading Style Sheets (CSS) offer a plethora of color options to bring life and vibrancy to your web designs. One such option is the HSL color model, which stands for Hue, Saturation, and Lightness. HSL provides a more intuitive way to describe colors compared to traditional RGB or hexadecimal values. In this article, we’ll delve into the world of CSS HSL colors, exploring their components and providing practical examples.
What is HSL?
HSL is a color model that defines colors based on three components:
- Hue: Represents the type of color, ranging from 0 to 360 degrees. It forms a color wheel where 0 and 360 both represent red, 120 is green, and 240 is blue.
- Saturation: Indicates the intensity or vividness of the color. It is expressed as a percentage, with 0% being grayscale and 100% being fully saturated.
- Lightness: Specifies the brightness of the color. It is also expressed as a percentage, with 0% being black, 100% being white, and 50% being normal.
Basic Syntax
The basic syntax for using HSL in CSS is as follows:
selector {
color: hsl(hue, saturation, lightness);
}Now, let’s explore this syntax with some practical examples.
Example 1: Basic HSL Color
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
body {
background-color: hsl(120, 100%, 50%);
color: hsl(240, 100%, 50%);
}
</style>
<title>HSL Color Example</title>
</head>
<body>
<h1>Welcome to the HSL Color World</h1>
<p>This is an example of using HSL colors in CSS.</p>
</body>
</html>In this example, the background color of the body is set to a fully saturated green (hue: 120), and the text color is set to a fully saturated blue (hue: 240).
Example 2: Adjusting Saturation and Lightness
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.box {
width: 200px;
height: 200px;
background-color: hsl(0, 100%, 50%);
margin: 20px;
display: inline-block;
}
.box:nth-child(2) {
background-color: hsl(60, 100%, 50%);
}
.box:nth-child(3) {
background-color: hsl(120, 100%, 50%);
}
</style>
<title>HSL Color Example 2</title>
</head>
<body>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
</body>
</html>In this example, three boxes are displayed with varying hues (red, yellow, and green) while keeping saturation and lightness constant.
