CSS Grid – Table layout is back. Be there and be square
I don't know how to say it politely but what has been achieved by using ad-hoc syntax such as this gem (and similar complex CSS syntax):<p><pre><code>    display: grid;
    grid-template-rows: 150px [nav-start]
        auto 100px [nav-end];
    grid-template-columns: [header-start]
        minmax(200px, 3fr) 9fr [header-end];
</code></pre>
CSS fans for some reason seem to think that its somehow better to have rendering/presentational properties in an ad-hoc language. Originally, plain markup attributes where designed to accomodate rendering properties, with type checking and all. The naive dichotomy established by putting "semantics" into markup and "presentational" properties into CSS was accidental, and it didn't make sense back then, nor does it now.
