Accéder à la couleur de catégorie en SCSS

Soutien

Hi there,

this is my first try at creating a custom theme, so please be understanding.

I’m trying to customize the category list page, so it should look like this:

The idea is to remove the left border and to add “pills”.
SCSS for adding pills is quite easy:

.category-list tbody .category {
    border-left: none;
    position: relative;
    padding-left: 50px;

    &::after {
        content: "";
        width: 20px;
        height: 80%;
        position: absolute;
        background-color: red;
        border-radius: 20px;
        top: 50%;
        transform: translateY(-50%);
        left: 10px;
    }
}

but I’m unable to access the category color that is available here: discourse/index.html.erb at 1472e47aae5bfdfb6fd9abfe89beb186c751f514 · discourse/discourse · GitHub

is there an easy way to access that color from CSS?

At the moment there’s not an easy way to do this.

What we could do is move these colors to CSS custom properties instead of setting them inline, which would make the colors easily accessible in any CSS/SCSS. I don’t know when we’ll be able to get to that, but I’ll keep it on my list of to-dos.

That would be awesome :slight_smile:
BTW is there any other way to achieve the view I want?
I’ve read that I can override templates for specific parts of Discourse, which template file I must override and how should I do that in my custom theme?

My current workaround is to override components/parent-category-row template.
I’m adding extra div element like this:

{{#unless noCategoryStyle}}
<div class="pill" style="background-color:#{{category.color}}"></div>
{{/unless}}

I’d like to avoid overriding templates because they might change in the future.

@awesomerobot a build-in way to access category color would be awesome :slight_smile:

@tjot,

Il est possible de faire un hack CSS avec la bordure du pseudo-élément ::after pour obtenir l’effet que vous souhaitez.

.category-list tbody .category {
    border-left: none;
    position: relative;
    padding-left: 50px;

    > h3:first-child {
        border-width: 0;
        border-style: solid;
        border-color: inherit;

        &::after {
            content: "";
            width: 0px;
            height: 70%;
            position: absolute;
            border-radius: 20px;
            border-width: 10px;
            border-style: solid;
            border-color: inherit;
            top: 50%;
            transform: translateY(-50%);
            left: 10px;
        }
    }
}

Notez que j’ai appliqué le style directement à l’élément h3 du titre car il est enfant direct du td auquel le style en ligne a été appliqué. Donc, si le modèle s’en débarrasse un jour, vous devrez ajuster votre CSS.

Mais vous pouvez ignorer la surcharge de components/parent-category-row comme vous le souhaitiez.
