Method 1 – display: grid
If you want the blocks placed in a grid using the display: grid property to have the same height, you can use the align-items property with the stretch value. For example:
1 2 3 4 5 | .grid-container { display: grid; grid-template-columns: 1fr 1fr 1fr; /* set three columns */ align-items: stretch; /* align blocks by height */ } |
This property stretches the blocks in each row to occupy the entire height of the row. However, if there is content inside the blocks with a fixed height or content that should not be stretched, additional adjustment may be required.
For example, if there are elements inside the blocks with absolute position, the position: relative property should be applied to the blocks to make them the context for the absolutely positioned elements.
If there are elements inside the blocks with a fixed height, the height: 100% property can be applied to make them occupy the entire height of the block.
Sometimes it may also be useful to set a fixed height for the blocks or use grid-auto-rows for the grid.
Method 2 – display: flex
If you use the display: flex property to arrange blocks in a row, to make them the same height, you can use the align-items property with a value of stretch. For example:
1 2 3 4 | .flex-container { display: flex; align-items: stretch; /* align blocks by height */ } |
Method 3 – JS
You can use JavaScript to align block heights. For example, you can write a function that finds the tallest block in a row and sets that height to all blocks in that row. Example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | function alignBlocks() { const rows = document.querySelectorAll('.grid-row'); rows.forEach(row => { let maxHeight = 0; row.querySelectorAll('.grid-item').forEach(item => { const height = item.offsetHeight; if (height > maxHeight) { maxHeight = height; } }); row.querySelectorAll('.grid-item').forEach(item => { item.style.height = maxHeight + 'px'; }); }); } // Call the function on page load and window resize window.addEventListener('load', alignBlocks); window.addEventListener('resize', alignBlocks); |
These are just some of the possible ways to align blocks by height. The choice of method depends on the specific task and requirements for compatibility and performance.
