This CSS Flex Generator is a free visual tool for creating Flexbox layouts directly
in your browser. It helps you experiment with Flexbox container properties such as
display, flex-direction, justify-content,
align-items, flex-wrap, row-gap and
column-gap.
You can also adjust individual flex item properties including flex-grow,
flex-shrink, flex-basis, align-self and
order. The tool updates the preview and generated code in real time,
making it useful for both learning Flexbox and quickly prototyping interface layouts.
Flexbox is ideal for horizontal navigation bars. Use display: flex,
align-items: center and justify-content: space-between
to align a logo, navigation links and buttons in one row.
A common Flexbox pattern is centering content both horizontally and vertically with
justify-content: center and align-items: center.
Flexbox can create equal-width columns by applying flex: 1 to each
item. This is useful for feature blocks, pricing sections and simple card rows.
Use flex-wrap: wrap and gap to create button groups,
tags or filters that wrap naturally on smaller screens.
CSS Flexbox, also called Flexible Box Layout, is a one-dimensional CSS layout system. It is designed to arrange items in a row or a column and gives you precise control over alignment, spacing, order and flexible sizing.
To create a flex layout, set display: flex on the parent element. All
direct child elements become flex items.
.parent {
display: flex;
}
The flex-direction property defines the main axis. Items can flow in a
row, reversed row, column or reversed column.
.parent {
display: flex;
flex-direction: row;
}
The justify-content property controls how flex items are distributed
along the main axis.
.parent {
display: flex;
justify-content: space-between;
}
The align-items property controls alignment along the cross axis. It is
commonly used to vertically center items in horizontal layouts.
.parent {
display: flex;
align-items: center;
}
By default, flex items stay on one line. With flex-wrap: wrap, items can
move onto additional lines when there is not enough space.
.parent {
display: flex;
flex-wrap: wrap;
}
Modern Flexbox supports the gap property. This is usually cleaner than
adding margins to individual items.
.parent {
display: flex;
gap: 1rem;
}
Individual flex items can grow, shrink and define their initial size using
flex-grow, flex-shrink and flex-basis.
.item {
flex-grow: 1;
flex-shrink: 1;
flex-basis: 200px;
}
The flex shorthand combines grow, shrink and basis values into one
property.
.item {
flex: 1 1 200px;
}
The order property changes the visual order of flex items. The
align-self property overrides align-items for a single item.
.item {
order: 2;
align-self: flex-end;
}
Flexbox is best for one-dimensional layouts, such as rows, columns, navigation bars, toolbars and aligned groups of items. CSS Grid is better for two-dimensional layouts where you need to control rows and columns at the same time.
