What is the CSS Grid Layout Generator?
The NexTools CSS Grid Layout Generator is a visual design environment created for web developers to effortlessly design two-dimensional responsive web layouts using the modern W3C CSS Grid specification.
CSS Grid is the most powerful layout system available in native CSS, enabling simultaneous row and column track alignments. However, computing fractional units (`1fr`), minimum and maximum boundaries (`minmax()`), and track gutter gaps (`grid-gap`) by hand can be counter-intuitive. Our visual tool provides immediate visual feedback as you adjust sliders, outputting clean, semantic CSS and HTML markup ready for production websites.

Frequently Asked Questions (FAQ)
What is the difference between CSS Grid and CSS Flexbox?
CSS Flexbox is primarily a one-dimensional layout model (handling content along either a row or a column), whereas CSS Grid is two-dimensional, allowing you to simultaneously coordinate rows and columns into a structured layout matrix.
What does the 'fr' unit mean in CSS Grid?
The `fr` (fractional) unit represents a fraction of the available free space within the grid container. A track definition like `1fr 2fr` allocates twice as much space to the second column as the first.
Is CSS Grid supported on all mobile and desktop browsers?
Yes. CSS Grid is supported natively across 99%+ of global browsers including Chrome, Safari, Edge, Firefox, and mobile Android/iOS browsers.
