CSS Color

CSS color is defined as the way to add color to HTML elements by using CSS (Cascading Style Sheets). It allows you to change the text color, backgrounds, borders, and other parts of your web page. With the help of CSS color, you can change the heading’s color to red or set the button’s background color to blue.

Types of CSS Color Values

You have several ways to apply CSS color to the HTML elements. Here, each way provides different flexibility to add CSS color. Let’s discuss each type of CSS color value:

1. Named Colors

Named colors are the most basic way to apply CSS color to the website elements. You can simply write the name of the color that you want, like red, blue, purple, etc.

Syntax:

p {
color: red;
}

Here, you are changing the color of the paragraph to red, where “red” is a named color.

2. RGB and RGBA Colors

RGB stands for Red, Green, and Blue. This format allows you to define a total of 16,777,216 colors just by using numbers from 0 to 255. While the RGBA format is the same as RGB, with one extra value called the alpha value that helps in controlling the transparency. This alpha value ranges from 0 (fully transparent) to 1 (fully solid).

Syntax:

/* RGB Format Example */
div {
background-color: rgb(0, 128, 255);
}

/* RGBA Format Example */
.box {
background-color: rgba(0, 128, 255, 0.5);
}

3. CSS HEX Colors

CSS color codes can also be written in the form of HEX values. A HEX value or HEX code is defined as a 6-digit code that starts with # and contains some numbers and letters.

4. HSL and HSLA Colors

HSL stands for Hue, Saturation, and Lightness. This format allows you to create colors based on the appearance of the color wheel. while HSLA is the same as HSL with an alpha value. You can use the alpha value to control the transparency.

Syntax:

/* HSL color format */
h2 {
color: hsl(120, 100%, 50%);
}

div {
background-color: hsla(120, 100%, 50%, 0.3);
}
