Setting different lengths for grid gaps in CSS Grid

Question

I'm creating a layout using CSS Grids, and I want to have different space between each row.

I can create the layout fine by just using margin on each element, but this kind of obscures the simplicity of the code. Is there any grid tricks I can do achieve this, grid-row-gap only seems to take one value, which it uses for all rows.

What I'm trying to achieve is a layout like this:

https://jsfiddle.net/8swzgk0b/1/

.grid {
  display: grid;
  grid-template-columns: auto 25% 25%;
  grid-template-rows: auto auto auto;
  width 100%;
  margin: 20px;
  grid-column-gap: 40px;
  /* grid-row-gap: 40px 60px; */
}

div {
  background: #838383;
  height: 80px;
}

.wide {
  grid-column: 1 / span 3;
  margin-bottom: 5px;
}

.row-2 {
  background: green;
  margin-bottom: 10px;
}

.row-3 {
  background: blue;
  margin-bottom: 30px;
}

.row-4 {
  background: red;
  margin-bottom: 20px;
}

<div class="grid">
  <div class="wide"></div>
  <div class="row-2"></div>
  <div class="row-2"></div>
  <div class="row-2"></div>
  <div class="row-3"></div>
  <div class="row-3"></div>
  <div class="row-3"></div>
  <div class="row-4"></div>
  <div class="row-4"></div>
  <div class="row-4"></div>
</div>

Is there any grid trick I can do to achieve this, grid-row-gap only seems to take one value, which it uses for all rows.

With the grid-row-gap, grid-column-gap and grid-gap properties, you cannot apply different widths to different gaps. Like you noted, only one value can be used for each axis: One for row gaps and another for column gaps (spec).

You could use margins (or padding) to show extra space, but this doesn't actually change the width of the gap. It only expands the row.

In the example below (based on your code), grid-row-gap is set to 20px. Grid items have the margin-bottom variations you set. Notice how the grip-row-gap size never changes. All changes occur inside the row.

.grid {
  display: grid;
  grid-template-columns: auto 25% 25%;
  grid-template-rows: auto auto auto;
  grid-column-gap: 40px;
  grid-row-gap: 20px;
}

div {
  background: #838383;
  height: 80px;
}

.wide {
  grid-column: 1 / span 3;
  margin-bottom: 5px;
}

.row-2 {
  background: green;
  margin-bottom: 10px;
}

.row-3 {
  background: blue;
  margin-bottom: 30px;
}

.row-4 {
  background: red;
  margin-bottom: 20px;
}

<div class="grid">
  <div class="wide"></div>
  <div class="row-2"></div>
  <div class="row-2"></div>
  <div class="row-2"></div>
  <div class="row-3"></div>
  <div class="row-3"></div>
  <div class="row-3"></div>
  <div class="row-4"></div>
  <div class="row-4"></div>
  <div class="row-4"></div>
</div>
