Grid Gap Properties obsolete?

I use VSCode and as I was following along with the practice, I noticed that my editor gave me a tooltip about the following properties being obsolete and I should avoid using them:

  • grid-row-gap
  • grid-column-gap
  • grid-gap

It also mentioned that I should now be using the gap property to define these gaps.

Hi Jamie

That is correct, these prefixed properties are being replaced, you should use the new name when using these.

As you can see, its the same name without the prefix of 'grid'

Hope this helps!

MDN shares this note regarding the items mentioned:

"CSS Grid Layout initially defined the grid-row-gap property. This prefixed property is being replaced by row-gap. However, in order to support browsers that implemented grid-row-gap and not row-gap for grid, you will need to use the prefixed property as in the interactive example above."

Does this imply we need to use both? or just the older version until the browsers catch up?

Personally, I would use both.

First with the deprecated property and second with the new property. That way you are supporting all browsers and preparing for future known breaking changes.

#grid {
  ...
  grid-row-gap: 20px;
  row-gap: 20px;
}
