Frequently Asked Questions

What is CSS Flexbox?
Flexbox (Flexible Box Layout) is a CSS layout model that provides an efficient way to lay out, align, and distribute space among items in a container, even when their sizes are dynamic.
What does align-content do vs align-items?
align-items controls how flex items are aligned along the cross axis within a single line. align-content controls how multiple lines are aligned when flex-wrap is enabled and there is extra space on the cross axis.
What is flex-wrap?
By default, flex items try to fit onto one line. flex-wrap: wrap allows items to wrap onto multiple lines when they exceed the container width.
Can I copy the generated CSS?
Yes. The tool shows the complete CSS declaration for your current configuration, which you can copy with one click.
