Archive page shows 2 columns instead of 3 at certain media queries

[milana_cap]

CSS used for these columns should be changed to something more reliable and up to date. This is what we have now:

@media (min-width: 48em)
.three-up .archive-block, .three-up > div {
    display: inline-block;
    vertical-align: top;
    width: 30%;
    margin-right: 4.5%;
    font-size: 0.8rem;
}

.three-up .archive-block:nth-child(3n), .three-up > div:nth-child(3n) {
    margin-right: 0;
}

Using either Flexbox or CSS Grid would make columns behave better.

In order to avoid the column issue, a list-format is better to show an index of all articles in a category.

There are several advantages:

• List can grow as needed
• no issues if one description is larger than another since there will be only rows and one column
• will simplify user interaction as the list will present 1 to 2 pages with articles instead of having to click through 6 screens to find what is needed

This patch looks fine to me.

Alternatively, we could give the inner container a width of 33.3333333% and add padding within that container, but that's just preference.

@estelaris Maybe we want to start a new ticket with your proposed changes to keep this one true and actionable? Adding a patch to fix the columns could improve experience while we figure out the best approach for this page.

@milana_cap I applied the patch although I recognize there are more instances that should be addressed. There are a few tickets that have advanced far enough to suggest real changes will happen to these layouts. So with that in mind, I have closed this out.
