Consider this HTML snippet using Tailwind CSS classes:
<div class="grid grid-cols-3 gap-4"> <div class="row-span-2 bg-blue-500 text-white p-4">A</div> <div class="bg-red-500 text-white p-4">B</div> <div class="bg-green-500 text-white p-4">C</div> <div class="bg-yellow-500 text-white p-4">D</div> </div>
What will you see rendered in the browser?
<div class="grid grid-cols-3 gap-4"> <div class="row-span-2 bg-blue-500 text-white p-4">A</div> <div class="bg-red-500 text-white p-4">B</div> <div class="bg-green-500 text-white p-4">C</div> <div class="bg-yellow-500 text-white p-4">D</div> </div>
Remember that row-span-2 makes the element cover two rows vertically in the grid.
The element with row-span-2 covers two rows in the first column. The next grid items fill the remaining cells in row-major order. So B and C fill the first row's second and third columns, and D fills the second row's second column.
You want a grid item to cover three rows vertically in a Tailwind CSS grid. Which class should you use?
Think about the difference between row-span and col-span.
row-span-3 makes the element span 3 rows vertically. col-span-3 spans columns, and row-start-3 or row-end-3 control grid line placement, not span.
When using row spanning in CSS grids, what should you keep in mind to maintain good accessibility?
Think about how screen readers read content versus how it looks visually.
Screen readers read content in the order it appears in the HTML. If the visual layout uses row spanning, the HTML order should still be logical to avoid confusion.
row-span2 instead of row-span-2 in Tailwind?Consider this Tailwind class: row-span2. What happens when you use it in your HTML?
<div class="grid grid-cols-3"> <div class="row-span2 bg-blue-500">A</div> </div>
Tailwind classes must match exact patterns to apply styles.
row-span2 is not a valid Tailwind class. The correct class is row-span-2. Invalid classes are ignored silently.
row-span-3 col-span-2 in a 4x4 grid?Given a 4 rows by 4 columns grid, an element has classes row-span-3 col-span-2. How many grid cells does it cover?
<div class="grid grid-cols-4 grid-rows-4 gap-2"> <div class="row-span-3 col-span-2 bg-purple-600 text-white p-4">X</div> <!-- other grid items --> </div>
Multiply the number of rows spanned by the number of columns spanned.
The element spans 3 rows and 2 columns, so it covers 3 × 2 = 6 grid cells.
