🎨 CSS Color Formats

CSS supports multiple color notations, each suitable for different purposes.

1. Named Colors

p {
  color: crimson;
}

✅ Readable and quick for basic use.

2. Hexadecimal (#RRGGBB)

p {
  color: #ff5733;
}

✅ Precise and commonly used in design tools.

---

3. RGB (rgb())

p {
  color: rgb(255, 87, 51);
}

✅ Allows control of red, green, and blue values separately.

---

4. RGBA (rgba())

p {
  color: rgba(255, 87, 51, 0.5);
}

✅ Includes transparency (alpha).

5. HSL (hsl())

p {
  color: hsl(14, 100%, 60%);
}

✅ Easier to tweak hue, saturation, and lightness.

🖼️ CSS Background Techniques

The background family of properties allows for powerful and flexible visual layering.

🧪 Example:

div {
  background-color: #f0f0f0;
  background-image: url('pattern.png');
  background-repeat: no-repeat;
  background-position: center;
  background-size: cover;
}

🔧 Common Properties:

Property	Purpose
background-color	Sets solid background color
background-image	Applies image to background
background-repeat	Repeats image (or not)
background-position	Sets image position
background-size	Defines scaling behavior (cover, contain)
background-attachment	Scroll or fixed background

✅ Combine these in one shorthand:

background: #fff url("bg.jpg") no-repeat center/cover;

✨ CSS Visual Enhancements

Make your backgrounds and colors dynamic with gradients and multiple layers.

1. Linear Gradients

---

2. Radial Gradients

background: radial-gradient(circle, #ff7e5f, #feb47b);

3. Multiple Backgrounds

background: 
  linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)),
  url("image.jpg") center/cover no-repeat;

✅ Layer multiple backgrounds with overlays and images.

---

4. Background Blend Modes

background-blend-mode: multiply;

✅ Allows creative effects when combining color and images.
