Background Color Code in HTML and CSS
The background color of an HTML element can be set using the background-color property in CSS. This property accepts a color value, which can be specified in several ways:
Color Name
You can use a color name directly, like red, blue, green, yellow, black, and white. These are standard color names recognized by all browsers.

Hexadecimal Color Code
Hexadecimal color codes are a six-digit combination of letters and numbers, starting with a hash symbol (#). Each pair of digits represents the intensity of red, green, and blue (RGB) in the color.

RGB Color Code
RGB color codes represent a color using three values for red, green, and blue, ranging from 0 to 255. They can be written as rgb(red, green, blue).

RGBA Color Code
RGBA color codes are similar to RGB but add a fourth value for alpha, which controls the opacity of the color. The alpha value ranges from 0 (fully transparent) to 1 (fully opaque).

HSL Color Code
HSL color codes use hue, saturation, and lightness to represent a color. Hue refers to the color itself, saturation is the intensity of the color, and lightness determines how light or dark the color is. They can be written as hsl(hue, saturation, lightness).

Applying Background Color in CSS
You can apply background color to HTML elements using various CSS methods:
- Inline Styles: The
styleattribute within an HTML tag allows you to directly apply CSS properties. - Internal Styles: You can define styles within the
<style>tag in the<head>section of your HTML document. - External Stylesheet: Create a separate CSS file and link it to your HTML document using the
<link>tag. This is the recommended approach for better organization and maintainability.
Example using an external stylesheet:
