 }  
 h1 {  
     color: var(--main-color);  
     font-size: var(--font-size);  
 }  
CSS Grid Layout:

Master grid-based design for powerful 2D layouts.
Key properties like grid-template-rows, grid-template-columns, and grid-gap.
Example:
 .container {  
     display: grid;  
     grid-template-columns: 1fr 2fr;  
     grid-gap: 10px;  
 }  
Flexbox (Advanced Techniques):

 li:nth-child(odd) { background-color: #f4f4f4; }  
 div:not(.active) { opacity: 0.5; }  
Media Query Breakpoints for Responsive Design:

Best practices for using breakpoints.
Example:
 @media (max-width: 768px) {  
     body { font-size: 14px; }  
 }  
CSS Animations:

Create smooth transitions with @keyframes and animation properties.
Example:
 @keyframes slideIn {  
     from { transform: translateX(-100%); }  
     to { transform: translateX(0); }  
 }  
 .box {  
     animation: slideIn 1s ease-in-out;  
 }  
CSS Transitions (Advanced Use Cases):

Chain transitions and add delays.
Example:
 button:hover {  
     background-color: #3498db;  
     transition: background-color 0.3s ease;  
 }  
CSS Transformations:

Apply rotate, scale, skew, and combinations.
Example:
 .card:hover {  
     transform: scale(1.1) rotate(5deg);  
 }  
CSS Frameworks (Tailwind, Bootstrap, etc.):

Overview of when and how to use frameworks for rapid development.
CSS for Accessibility:

Styling focus states, ARIA roles, and ensuring contrast ratios.
Example:
  a:focus { outline: 2px dashed #3498db; }  
CSS for Dark Mode:

Leveraging @media (prefers-color-scheme) for dark mode.

  }  
CSS Counters:

Dynamically number elements using counter-reset and counter-increment.
Example:
  ol { counter-reset: section; }  
  li::before { content: counter(section) ". "; counter-increment: section; }  
CSS Shape and Clipping:

Use clip-path and shapes for creative layouts.
Example:
  .circle {  
      clip-path: circle(50%);  
  }  
CSS Masking and Blending Modes:

Experiment with mask-image and mix-blend-mode.
Example:
  .image {  
      mask-image: url(mask.png);  
      mix-blend-mode: multiply;  
  }  
CSS Scroll-Snapping:

Smooth scrolling with scroll-snap-type and scroll-snap-align.
Example:

      scroll-snap-type: x mandatory;  
  }  
  .item {  
      scroll-snap-align: center;  
  }  
CSS Logical Properties:

Use logical properties for multi-directional layouts (margin-inline, padding-block).
