Tailwind CSS Gap Classes such as gap-[size], are used to define the gap or spacing between grid or flex container child elements. These classes simplify the management of spacing, creating consistent layouts by controlling the space between elements horizontally (with gap-x-[size]) and vertically (with gap-y-[size]).

Syntax:

<div class="grid grid-cols-2 gap-4">
  <!-- Child elements with a horizontal gap of 4 units -->
</div>

<div class="flex gap-6">
  <!-- Child elements with a horizontal gap of 6 units -->
</div>

Here, the gap-[size] Class defines the gap or spacing between child elements. Replace [size] with spacing values like 4, 8, px, etc. Here (size) values range from 0 to 96.

Key Features:

• Grid and Flex Spacing: Use gap-[size] classes in both grid and flex containers to control the spacing between child elements.
• Consistent Layouts: Easily maintain consistent spacing between elements, ensuring a clean and organized design.
• Responsive Design: Employ responsive variants (sm:, md:, lg:, xl:) for adaptive gap sizes at different screen sizes.
