Critical CSS Optimization for a Faster First Load
A critical CSS optimization service pulls the styles needed for the top of each page into the HTML itself and loads the rest later. Omeiro extracts the above-the-fold CSS, inlines it and loads secondary stylesheets asynchronously, so pages start drawing without waiting on a stylesheet request.

How our critical CSS optimization works
Measure
We record current speed scores.
Extract
Above-the-fold styles are identified per template.
Inline and defer
Critical rules are inlined and other CSS loads later.
Check
We test for style flashes and rerun Lighthouse.
Critical CSS: what to know before it is built
Critical css behaves differently per template, because a home page, a product page and a blog post show different elements above the fold. That is why packages count templates rather than pages. Before ordering, list your main templates and tell us which theme or framework you use and whether stylesheets come from plugins. Third-party styles that load late are often the real cause of a slow first paint.
The trade-off is maintenance. Inlined styles add a little to the HTML size and can fall out of date when the design changes, so the extraction should be repeatable. We also check different screen widths, since above the fold on a phone is not the same as on a desktop. Done well, critical css gives the browser what it needs to paint immediately while the rest of the stylesheet arrives without blocking.

What happens when I change the theme?
