Thanks to @chapel for sharing his customizations ☀

Is there a way to isolate the code that make the category bars coloured?

The css part would be something like this:

```css
$color1: #30A92A;
$category-opacity: 0.3;

.category-bar {
    margin: 0 !important;
    padding: 0 !important;
    width: 2px;
    
    .category-meta & {
        background-color: rgba($color1, $category-opacity);
    }
}

```

…but i tried different combinations on the header part and i can’t get this to work..
