Introduction to CSS Colors.


Mastering CSS Colors: A Complete Beginner's Guide
Colors are one of the first things you notice in a web page and also one of the most powerful tools whether you’re building a landing page, blog or an e-commerce store. CSS creates mood, reinforce brand identity, and improve readability. In CSS (Cascading Style Sheets), understanding how to control colors allows you to create beautiful, accessible, and memorable designs.
🌈 What Are CSS Colors?
CSS colors can be applied to text, backgrounds, borders, and even shadows. They help set the mood of a webpage—bold, minimal, vibrant, or soft.

🔢 1. Color Formats in CSS
There are several ways to define colors in CSS. Here’s a breakdown:
✅ Named Colors
CSS provides around 140 predefined color names like red
, blue
, crimson
, mintcream
.
cssCopyEdith1 {
color: crimson;
}
📷 Example:
✅ HEX Codes
The most common format. HEX stands for hexadecimal—a 6-digit code beginning with #
.
cssCopyEditp {
color: #3498db;
}
🔍 #3498db
is a shade of blue.
✅ RGB and RGBA
RGB stands for Red, Green, Blue.
cssCopyEditbody {
background-color: rgb(255, 255, 255); /* white */
}
Add transparency with RGBA:
cssCopyEditdiv {
background-color: rgba(0, 0, 0, 0.5); /* semi-transparent black */
}

}
