This property defines the direction of the main axis. It controls how items are placed inside the flex container.
row – items are placed from left to right (default)column – items are placed from top to bottomrow-reverse – right to leftcolumn-reverse – bottom to topJustify-content aligns items horizontally. It is very useful for navigation bars and evenly spaced designs.
Align-items controls vertical alignment inside the container. It helps to center elements vertically without extra code.
When there are too many items in one row, flex-wrap allows them to move to a new row. This is great for mobile-friendly layouts.
The gap property defines the space between elements. It replaces older techniques like margins.
Flexbox is perfect for navigation bars because we can easily align items, manage spacing, and create responsive menus.
Multiple product cards or article blocks can be arranged using flexbox with equal spacing and alignment. This method is used in modern e-commerce and blog websites.
Forms become more clean and structured when flexbox is used to align labels and inputs.
Practice small layouts using Flexbox. Try building headers, footers, card sections, image galleries, and navigation menus. This visualizer tool will help you understand properties quickly and gain confidence in CSS design.
