Core CSS Layout Concepts

What is a Gap?

Gap creates space between elements without adding margins. Think of it like an invisible spacer that keeps things neatly apart - just like the space between train cars.

/* CSS */
.container {
  gap: 1rem;  /* Adds 1rem of space between all items */
}

/* Tailwind */
<div className="gap-4">  <!-- 1rem of space between items -->
  <div>Item 1</div>
  <div>Item 2</div>
</div>

What is Spacing?

Spacing helps organize content by controlling the distance between elements. It's like making sure there's enough room between books on a shelf so you can easily grab the one you want.

/* Tailwind classes for spacing */
p-4    /* Padding on all sides */
px-4   /* Horizontal padding (left and right) */
py-4   /* Vertical padding (top and bottom) */
m-4    /* Margin on all sides */
mx-4   /* Horizontal margin */
my-4   /* Vertical margin */

One vs Two Dimensional Layout

Flexbox works in one direction (like a line of people), while Grid works in two dimensions (like a chess board). Flexbox is perfect for rows or columns, while Grid excels at complex layouts with rows AND columns.

/* Flexbox - One dimension */
<div className="flex">  <!-- Items arranged in a row -->
  <div>Item 1</div>
  <div>Item 2</div>
</div>

/* Grid - Two dimensions */
<div className="grid grid-cols-3 grid-rows-2">  <!-- 3×2 grid -->
  <div>Item 1</div>
  <div>Item 2</div>
  <!-- ... -->
</div>

Alignment vs Justification

Alignment controls positioning along the cross axis, while justification controls the main axis. Think of it like a bookshelf: justification arranges books across the shelf, while alignment controls how tall books are positioned vertically.

/* In a horizontal flexbox: */
justify-start   /* Position items at the start (left) */
justify-center  /* Center items horizontally */
justify-end     /* Position items at the end (right) */

items-start     /* Align items at the top */
items-center    /* Center items vertically */
items-end       /* Align items at the bottom */
