Core Concepts

• Grid Container - The parent element with display: grid
• Grid Items - Direct children of the grid container
• Grid Lines - The dividing lines that create the grid structure
• Grid Areas - Rectangular areas between grid lines

Advanced Features

.container {
  display: grid;
  grid-template-columns: 1fr 2fr 1fr;
  gap: 20px;
}
