Adding spacing between grid items using css gap property

Jul 13, 2025 am 12:58 AM

When using CSS Grid layout, the easiest and most effective way is to use the gap attribute to add spacing between grid items. Gap is an abbreviation property for setting row-gap and column-gap at the same time. For example, .grid-container { display: grid; gap: 20px; } can set a 20px spacing for all adjacent grid items; if you need to set it separately, you can use gap: 10px 20px;. Notes include: 1. The parent container must be set to grid layout; 2. The gap does not affect margins; 3. Good compatibility but old browsers may need to be prefixed. Common problems and solutions are: 1. If the container is not correctly set to grid layout, display: grid should be checked; 2. If the grid item has negative margins that affect the gap, you can use the developer tools to check the spacing; 3. If the fixed size causes the gap to be less obvious, you can try to increase the gap value to test the effect.

Adding spacing between grid items using css gap property

When using CSS Grid layout, the easiest and most effective way to add spacing between grid items is to use gap attribute. It allows you to easily control the gap between rows and columns without the need to set margin or padding.

Adding spacing between grid items using css gap property

What is gap attribute?

gap is an abbreviation property in CSS Grid, which is used to set row-gap and column-gap gap at the same time.
You can use it like this:

Adding spacing between grid items using css gap property
 .grid-container {
  display: grid;
  gap: 20px;
}

In the example above, all adjacent grid items will maintain a 20px spacing, whether horizontally or vertically. If you only want to set the spacing between rows and columns separately, you can also write it like this:

 gap: 10px 20px; /* row-gap column-gap */

Things to note when using gap

Although gap is simple and easy to use, there are several details to pay attention to:

Adding spacing between grid items using css gap property
  • The parent container must be grid layout : gap will only take effect when the element has display: grid set.
  • Will not affect margins : gap only controls the spacing between grid items and does not create additional white space at the edge of the container.
  • Good compatibility : Modern browsers basically support gap , but in some older versions -ms-grid-row-gap and -ms-grid-column-gap may be required.

Frequently Asked Questions in Practical Applications

Sometimes you will find that you have set up gap but you don’t see any effect. This may be caused by the following situations:

  • The container is not correctly set to grid layout
  • The grid term itself has a negative margin offsets the gap
  • Fixed sizes of grid-template-columns or grid-template-rows are used, resulting in visual inconspicuousness.

The solution is very simple:

  • Check if display: grid is written
  • Check the position and spacing of each grid item with browser developer tools
  • Try setting a larger gap value to test whether it takes effect

Let's summarize

It is very convenient to use gap to add spacing to grid, and it only takes one line of code to do it. Remember that it only acts between grid items and does not affect the external boundaries of the overall layout. If you encounter an invalid situation, first confirm whether the container has really become a grid layout. Basically that's it.

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
