🔧 What is Flexbox?

Flexbox (Flexible Box Layout) is a one-dimensional layout model designed for arranging items in a row or column. It excels at distributing space along a single axis and is perfect for aligning elements horizontally or vertically.

✅ Key Features of Flexbox:

• Layouts along one axis (row OR column)

• Automatic spacing and alignment

• Dynamic resizing of child elements

• Works well for components like navbars, cards, and forms

🧱 What is CSS Grid?

CSS Grid Layout is a two-dimensional layout system that allows developers to design layouts using rows AND columns simultaneously. It’s ideal for creating full-page layouts or complex design structures.

✅ Key Features of Grid:

• Layouts in both horizontal and vertical directions

• Explicit placement of elements

• Easily create overlapping components

• Great for building responsive page structures and dashboards

grid-template-columns: 1fr 3fr;
gap: 10px;
}
