The Complete CSS Flexbox Guide With a Complete Project 2025

Explore how justify-content shapes alignment on the main axis by distributing remaining space with flex-start, flex-end, center, space-between, and space-around, also usable vertically in a column layout.

Explore how justify content behaves when the flex flow is row reverse or column reverse, demonstrating horizontal and vertical alignment changes with flex start and end.

Demonstrate how align-items controls flex container items along the cross axis, including flex-start, flex-end, center, and stretch, with row and column flows; compare to justify-content.

Learn how align-self applies to a single flex item to override align-items using values like flex-start, center, and stretch. See how this differs from aligning all items with align-items.

Control how multiple lines in a flex container are distributed using the align-content property, with values like center, flex-start, flex-end, space-between, and space-around to arrange lines.

Learn how the order property reorders flex elements without changing the source order, using default zero, positive values to shift items, and negative values to place an item first.

Explore how flex grow controls width in a row and height in a column, how remaining space is distributed, and how to make a single item expand.

Discover how flex shrink property governs how flex items shrink when space runs out, with default 1, zero or higher values, and how flex-wrap wraps items to the next line.

Define the flex basis to establish the initial main size of a flex item before space distribution, acting like width and accepting pixels, percentages, auto, or zero for equal widths.

Start using flex box to build two real-world menus with the properties learned in the previous videos, using the startup HTML, CSS, Font Awesome, and Google Fonts files.
