In the CSS file, selectors in line 17-20 are aligning headings and data for columns containing numbers right. Is there a shorter or better way to target (select) them? Writing 4 lines for that feels like writing bad code.

Hi @user.dev and welcome to the community 👋

You could reduce all the left/right alignment rules to the code below, but I think that about the most reduction you could get.

```auto
tr :nth-child(2),
tr :nth-child(3),
tfoot th {
  text-align: right;
}

tr,
tfoot :nth-child(2) {
  text-align: left;
}

```

There’s another possibility to style entire columns, but only a few properties are supported (border, background, width, visibility). Therefore this wouldn’t work with `text-align`, but maybe it’s helpful in another situation: [`<colgroup>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/colgroup) and classes on individual `<col>`s inside.

I hope that helps, 🙂
