Can’t figure out why CSS grid layout adds an unwanted extra space to content around the vertical cells, though margin and padding are zeroed out:
.grid {
display: grid;
grid-template-columns: 13fr 11fr 4fr 20fr;
grid-auto-rows: 12fr;
grid-gap: 4px;
align-items: center;
}
.grid figure {
outline: 1px solid red;
margin: 0;
padding: 0;
}
.grid figure img {
margin: 0;
padding: 0;
width: 100%;
display: block;
}
.grid .gi13x12 {
grid-column-start: 1;
grid-column-end: 2;
grid-row-start: 1;
grid-row-end: 13;
}
.grid .gi11x6.one {
grid-column-start: 2;
grid-column-end: 3;
grid-row-start: 1;
grid-row-end: 7;
}
.grid .gi11x6.two {
grid-column-start: 2;
grid-column-end: 3;
grid-row-start: 7;
grid-row-end: 13;
}
.grid .gi4x4.one {
grid-column-start: 3;
grid-column-end: 4;
grid-row-start: 1;
grid-row-end: 5;
}
.grid .gi4x4.two {
grid-column-start: 3;
grid-column-end: 4;
grid-row-start: 5;
grid-row-end: 9;
}
.grid .gi4x4.three {
grid-column-start: 3;
grid-column-end: 4;
grid-row-start: 9;
grid-row-end: 13;
}
.grid .gi20x12 {
grid-column-start: 4;
grid-column-end: 5;
grid-row-start: 1;
grid-row-end: 13;
}

Your image just wasn't occupying the entire height of its container and that's why it appeared you had a gap there. In your current solution your borders are uneven as your imgs have no height assigned to them.
By default, a grid item cannot be smaller than the size of its content. Grid items have an initial size of min-width: auto and min-height: auto . You can override this behavior by setting grid items to min-width: 0 , min-height: 0 or overflow with any value other than visible .
The row-gap CSS property sets the size of the gap (gutter) between an element's rows.
The vertical gaps are caused by the images not filling the vertical space in the grid items.
The problem is made worse with align-items: center
on the container, which removes the align-items: stretch
default.
Essentially, there are no gaps between grid items. They form a clean, neatly-arranged grid. But because the images are smaller than the items that contain them, and the items are then centered vertically with align-items
, there are lots of gaps.
Here's a more detailed explanation, using Firefox's grid overlay tool for illustration:
(1) This is your grid when grid-row-gap
and grid-column-gap
are 0:
The red lines represent the grid items. The images are the content of the grid items. The dotted lines represent the grid lines.
(2) There is no problem when grid-column-gap
is 10px:
(3) But look what happens when grid-row-gap
is 10px:
The grid items (red lines) neatly wrap their content (the images). This happens only because the container is set to align-items: center
.
(4) Now let's removes align-items: center
(which restores the default stretch
value) and keep grid-column-gap: 10px
and grid-row-gap: 10px
:
As you can see, the grid items (having red borders and yellow backgrounds) now expand full height. But the images, being smaller than the items, leave gaps.
(5) Here's the grid from (4) above without the indicators.
align-items: stretch
align-items: center
(same layout as in the question)
(6) So the key is to get the images to fill the grid items.
One simple solution is to apply display: flex
to the grid items, which will automatically assign align-items: stretch
to the images, causing them to take full height.
And then, depending on how you want the images to look, you can use object-fit
to manage their appearance.
Add this to your code:
.grid figure {
display: flex;
}
.grid figure img {
object-fit: cover; /* also try `contain` and `fill` */
}
With the adjustments above, the grid renders like this:

}

Cool grid overlay feature in Firefox
In Firefox dev tools, when you inspect the grid container, there is a tiny grid icon in the CSS declaration. On click it displays an outline of your grid on the page.

Note, this answer where posted prior to the latest update, and as such, answer the initial code sample (the one within the question) differently. The edited version of the question is brilliantly answered by Michael.
First, the inner space has nothing to do with CSS Grid, margin or padding, it comes from the fact that an img
is an inline element, which like characters has a white space, for descenders, below the baseline.
One solution for that is to add display: block
to the .grid figure img
rule.
.grid figure img {
display: block;
width: 100%;
}
Second, the outer space is caused by the grid-auto-rows
, so remove that from the .grid
rule.
.grid {
display: grid;
grid-template-columns: 13fr 11fr 4fr 20fr;
/*grid-auto-rows: 12fr; remove this */
grid-gap: 3px;
align-items: flex-start;
}

Regarding your Fiddle sample (and added screen dump), where neither matching the inner code sample, and after the above adjustments, there is still a small inner space, which is caused by the fact that the sum of the smaller elements height does not match the highest one, nor does its images, as the highest image is 123px, but smaller images are 120px (2*60) and 117px (3*39).
