I actually prefer the white ring in dark mode. I think it differentiates the records MUCH more clearly than a darker ring. Perhaps we could use a light grey, rather than white/“black”?

The intent of the box shadow is to separate near-by records. The fact that some records get it but not others makes the white jarring. The color of the record itself makes it clear that there is a record at all.

NIT: I'd make this name more specific (e.g. `--timeline-record-bar-box-shadow-color`) so its indented usage is clearer.

Could we just use `--selected-background-color-unfocused` instead (as in remove this variable entirely and use that instead)?

> Source/WebInspectorUI/UserInterface/Views/OverviewTimelineView.css:67
> +.timeline-view.overview > .data-grid tr:nth-child(even) {

This makes me think that the box-shadow's color should match the background color of that row, which doesn't seem to be the case in the screenshots.  That's what the Network timeline does in the overview, and I personally like that quite a lot.  Perhaps we can just use `--even-zebra-stripe-row-background-color` and `--odd-zebra-stripe-row-background-color` instead?

r-me, nice fix!

We spoke about this in person, but I think we should switch it such that the first row is the one with the "odd" background color (e.g. it's different from the background color of the surrounding content, like a navigation bar).  This way, it's easier to identify where the table begins, because the first row has a different background color.  I'm also fine with that being a followup.

I think this is missing a `* UserInterface/Views/Main.css:`

> Source/WebInspectorUI/UserInterface/Views/DataGrid.js:1145
> +        this._dataTableElement.classList.toggle("even-first-zebra-stripe", !!(topHiddenRowCount % 2));

We should probably add a comment like "if there are an odd number of rows hidden, meaning that the first visible row must be an even row".

> Source/WebInspectorUI/UserInterface/Views/OverviewTimelineView.css:97
> +        --timeline-record-bar-selected-inactive-box-shadow-color: hsla(0, 0%, 35%);

This can just be `hsl()`.

> Source/WebInspectorUI/UserInterface/Views/OverviewTimelineView.css:101
> +        --timeline-record-bar-selected-inactive-box-shadow-color: hsla(0, 0%, 38%);

Ditto (97).

> Source/WebInspectorUI/UserInterface/Views/Table.js:1130
> +        this._listElement.classList.toggle("even-first-zebra-stripe", !!(topHiddenRowCount % 2));

Ditto (DataGrid.js:1145).
