Key Concepts of Flexbox

• Flex Container: The parent element that establishes the layout for its child elements.
• Flex Items: The child elements within the flex container.
• Flex Axis: The direction in which the flex items are arranged within the container (horizontal or vertical).
• Cross Axis: The axis perpendicular to the flex axis.
• Flex Direction: Controls the direction in which flex items are placed along the flex axis (row, row-reverse, column, column-reverse).
• Flex Wrap: Determines whether flex items should wrap to a new line or overflow.
• Justify Content: Aligns flex items along the main axis.
• Align Items: Aligns flex items along the cross axis.

Basic Flexbox Example

<div class="container">
  <div class="item">Item 1</div>
  <div class="item">Item 2</div>
  <div class="item">Item 3</div>
</div>

<style>
  .container {
    display: flex;   
    flex-direction: row;
    justify-content: space-between;
  }

  .item {
    border: 1px solid black;
    padding: 10px;
    flex-grow: 1;
  }
</style>

In this example:

• The .container div is set to display: flex to establish it as a flex container.
• The flex-direction: row property arranges the items horizontally.
• The justify-content: space-between property distributes the items evenly within the container.
• The .item divs are set to flex-grow: 1 to make them expand to fill the available space.

• Order: Controls the order in which flex items appear.
• Align-self: Aligns a specific flex item along the cross axis.
• Flex-basis: Sets the initial size of a flex item before it grows or shrinks.
