This course is created and taught by the instructor. In this updated version, AI tools were used in a limited capacity to help refine introduction lecture articles. All explanations, concepts and teaching are original and based on the instructor’s own understanding and experience.

This course is designed to help you elevate your HTML webpage layouts using the power of CSS Flexbox, a layout model that gives you precise control over alignment, spacing, and responsiveness.

You’ll learn how each Flexbox property works through clear demonstrations, covering both parent container properties and child item properties.

Properties applied to the parent flex container:

• flex-direction – Set the direction items are laid out (row or column)

• flex-wrap – Control whether items wrap or stay on a single line

• flex-flow – Combine flex-direction and flex-wrap with a shorthand

• justify-content – Align items along the main axis (e.g., left, center, space-around)

• align-items – Align items along the cross axis

• align-content – Control spacing between multiple lines of items

Properties applied to individual flex items:

• flex-basis – Define an item’s initial size before space is distributed

• flex-grow – Distribute remaining space between flex items

• flex-shrink – Control how items shrink when space is limited

• flex – A shorthand for setting flex-grow, flex-shrink, and flex-basis

• order – Change the visual order of items

• align-self – Override alignment for a specific item

To build a deeper understanding, you’ll also see Flexbox in action across a range of scenarios, helping you clearly connect each property to its real-world effect.

By the end of this course, you’ll not only understand how to use Flexbox, you'll also know why it behaves the way it does, giving you greater confidence and control when building flexible layouts.
