CSS has gotten easier to write than it is different to write.

• use :is to group multiple selectors such as a:hover and a:focus
• using logical properties instead of marg
• margin-trim can help by removing the last margin child element of a list for example. It is experimental, so Flexbox with the gap property
• aspect-ratio to set only one dimension between the height and the width, while keeping proportions
• .card:has(:hover, :focus) is easier and straightforward than a.card-link:hover > .card
• an easier way to define color palette with --gray-dark: color-mix(in srgb, var(--primary-color), [#fff](https://shaarli.lyokolux.space/./add-tag/fff) 25%);. It is more maintainable!
• ch for managing line lengths; text-wrap: balance is a work in progress (65% of users can use it)

and more with cascade layers, container queries, <selectmenu> and CSS nesting
