How do you set alternating colors in the list of topics? It helps usability a lot, but it is all white by default. example: [image]

You can achieve this with a CSS customization. Here’s an example to get you started: .topic-list-item:nth-child(even) { background-color: #EEE; } .topic-list-item:nth-child(odd) { background-color: #FFF; } Here’s how this looks on Meta: [image]

And for those who are looking to change the background of topics, here’s the solution: div.topic-post:nth-child(odd), div.small-action:nth-child(odd) { background-color: #FAFBFF; } div.topic-post:nth-child(even), div.small-action:nth-child(even) { background-color: #F6F6FF; }

And here’s the discussion about why it isn’t the default anymore: https://meta.discourse.org/t/the-death-of-the-grey-no-more-tiger-striping-rows-by-default/28664?u=falco

@fefrei Care to extract this into a super simple theme component? :blush: @Silvanus same for your topic tweak. I was thinking maybe we’d just include it in the “tiger striping component” but commented out by default, but we might as well make it a component of its own as they really are two completely separate pieces of styling.

[image] erlend_sh: Care to extract this into a super simple theme component? :blush: Sure! Can you tell me why I cannot use $primary-low in the theme component? It’s used all over the place in core (e.g. as the background color of buttons), and I think it’s a good color for the darkened rows, but it’s undefined: Error: Undefined variable: "$primary-low". on line 2 of theme_field.scss >> background-color: $primary-low; ----------------------^

I’ve run into the same problem. What solved it for me was adding this at the top: @import "common/foundation/variables"; And then you can use those colors. That’s the short story, the long story is here: [image] Use Discourse Core Variables in your Theme Developer Guides Discourse is incredibly customizable! The goal of this topic is to show you how make use of all the amazing options that are available to you as a theme developer. You know… so that you don’t have to reinvent the wheel smile Variables? What variables? Variables cover a large number of things, from font sizes to colors to z-index values. You can use and override the vast majority of variables in your theme editor.

That did it, thanks :heart: Here you go: https://github.com/fefrei/discourse-tiger-stripes

Why not :zebra: stripes? I guess :tiger: stripes are less… black and white?
