Coloring every other row using CSS Grid

Question

I want to color every other row in a table i'm building using CSS Grid. I can't get it to work though, i'm only able to get every other column colored. Here's a picture of what I want to do. Would there be a better way of building this out? I'm only using CSS Grid because it's something new I wanted to learn.

Here's my current code:

  .wrapper {
  border-style: solid;
  border-color: rgb(230, 230, 230);
  font-weight: bold;
  text-align: center;
  display: grid;
  grid-template-columns: repeat(6, 1fr);
  grid-template-rows: repeat(18, 35px);
  grid-column-gap: 0px;
  grid-row-gap: 0px;
}

.wrapper>div:nth-child(odd) {
  background: #ddd;

Honestly for a table using a table element is the best choice. You can then use `tr:nth-child(even)` (or odd) to style your rows. If you want to learn grid then build a grid layout, not a table. Something like a sidebar, a grid of images in a gallery. — cloned, Oct 05 '19 at 19:25

if you have a six column grid, then you have a new row every 6+1 elements, for an alternative pattern on each odd rows, then your repeating patterns starts every 12+1 elements. :nth-child(n+n) will help you here :

.wrapper {
  border-style: solid;
  border-color: rgb(230, 230, 230);
  font-weight: bold;
  text-align: center;
  display: grid;
  grid-template-columns: repeat(6, 1fr);
  grid-template-rows: repeat(18, 35px);
  grid-column-gap: 0px;
  grid-row-gap: 0px;
}
/* 6 columns, odd rows starts every 12th element, a row is made of six elements, so here is 6 selectors to select an entire row*/
.wrapper>div:nth-child(12n+1),
.wrapper>div:nth-child(12n+2),
.wrapper>div:nth-child(12n+3),
.wrapper>div:nth-child(12n+4),
.wrapper>div:nth-child(12n+5),
.wrapper>div:nth-child(12n+6)
{
  background: #ddd;
  }

Note: if any of your elements spans more than 1 cell, the :nth-child(n+x) rule will break.

https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-child#examples

:nth-child()

The :nth-child() CSS pseudo-class matches elements based on their position in a group of siblings.

A link to information on `:nth-child(n+n)` (even if it seems obvious) would be helpful. It's difficult to search for something like this, since we aren't provided a name for the technique. — BBaysinger, Aug 31 '21 at 11:14

You are defining a fixed height for each row so you can easily consider a repeated gradient:

.wrapper {
  border-style: solid;
  border-color: rgb(230, 230, 230);
  font-weight: bold;
  text-align: center;
  display: grid;
  grid-template-columns: repeat(6, 1fr);
  grid-template-rows: repeat(18, 35px);
  background:
    repeating-linear-gradient(#ddd 0 35px,transparent 35px 70px);
}

<div class="container">
  <div class="wrapper">
    <div>Month</div>
    <div>Overtime Hours</div>
    <div>Compensation Hours</div>
    <div>Vacation</div>
    <div>Personal Hours</div>

this works, but how, what is repeating-linear-gradient doing? also gap will break this table? and you also cant justify-self on child items, as they would also break the table. — Ricky-U, Oct 22 '20 at 10:10
It worked so nicely until I scrolled my grid to the left within its scrollable div. On Chrome, it only shades the originally-visible portion, prior to scrolling. — Joe Lapp, Jun 02 '22 at 23:23
