🎨 Mastering CSS Flexbox: Layouts Made Easy

🚀 Getting Started with Flexbox

During my internship with @devsync , I took a deeper dive into the layout side of CSS—and the concept that stood out the most was Flexbox.

Whether you're building a responsive website or aligning items precisely, CSS Flexbox makes layout management easier and more intuitive.

💡 Why Flexbox is a Game-Changer

📱 It’s responsive by design.

🔧 No more hacks with floats and positioning.

📦 It helps manage space within a container—even when the size of the items is unknown.

🛠️ CSS Flexbox Essentials

✅ 1. Display: Flex

.container {
  display: flex;
}

✅ 2. Flex Direction

Choose the main axis: row (default) or column.

.container {
  flex-direction: row; /* or column */
}

✅ 3. Justify Content

Aligns items horizontally (along main axis).

.container {
  justify-content: space-between; 
  /* other options: flex-start, flex-end, center, space-around, space-evenly */
}

✅ 4. Align Items

Aligns items vertically (along cross axis).

.container {
  align-items: center;
}

✅ 5. Flex Wrap

Prevent items from overflowing the container.

.container {
  flex-wrap: wrap;
}

✅ 6. Gap

Add spacing between items easily:

.container {
  gap: 20px;
}

✅ 7. Align Self (Individual Item Control)

Override alignment for one item:

.item {
  align-self: flex-end;
}

🎨 Example: Responsive Card Layout

✅ HTML

<div class="container">
  <div class="card">Card 1</div>
  <div class="card">Card 2</div>
  <div class="card">Card 3</div>
</div>

✅ CSS

.container {
  display: flex;
  flex-wrap: wrap;
  gap: 15px;
  justify-content: space-between;
}

.card {
  flex: 1 1 30%;
  padding: 20px;
  background: #f3f3f3;
  border-radius: 8px;
}
