Thin Theme 6.00 is out, and 6.01 right behind it with the fixes that came out of the first day on our own demo stores.
The headline: the theme now comes with a new add-on, Fast Blocks.
It stops the storefront from building blocks it is not going to show. Blocks you hid on phones in the layout editor are no longer built for phones at all: no queries, no HTML, no cache entry. Heavy blocks below the first screen leave the first response and load as the visitor scrolls to them, behind a skeleton that repeats their shape.
The theme is ready for it out of the box: the shipped layouts already carry the lazy markup, so a fresh install needs nothing configured by hand. On our demo home page that is 373 KB → 186 KB on desktop and 360 KB → 170 KB on a phone.
Main content, product filters, breadcrumbs, the cart and every checkout step are never deferred, so nothing about the order flow changes.
Also in 6.00:
- product lists pick the picture size for the screen: sharp on retina, no oversized downloads
- theme colours are CSS variables now, so a shop can be restyled without recompiling the theme
- the carousel and animation libraries load only when a block really uses them
- the demo menu installs from the add-on settings, and its pictures and links stay inside your store
- a category without a picture shows a clean tile instead of a broken-image box
- language switcher links got accessible names
- the content of the shipped layouts is translated into every language of the theme
- fixed the price filter slider and the product filters block on the category page
- theme settings are grouped
6.01 fixes carousel pictures for stores with the HiDPI add-on (a lazy slide could show a broken picture), gives responsive sources to the single banner block, and makes scrollers keep their row while the page is still loading.
Both updates arrive through the Upgrade Center.
