sprite css background images ...

Hi,

I’ve build a small test page with 13 css background images (all the same size, but different images), a small portion of text plus 4 additional img resources at the bottom.

WPT doesen’t complain about “Combine images into CSS sprites” at all on testing this page.

Are there any rules in WPT which determine whether CSS spriting plays a role in the big picture?
My testpage scores at 97% - well, there is no much room for pss improvement :wink: But 13 sprite-able images are a thing which should count.

Thx,

The Page Speed part of the check isn’t something I control (WebPagetest proper focuses mostly on the waterfall and the grades at the top). If you have questions about the Page Speed checks it’s probably best to ask here: https://groups.google.com/forum/#!forum/page-speed-discuss (and maybe verify with Page Speed Insights which is running a newer version of their checks - https://developers.google.com/speed/pagespeed/insights ).

… ahh ok, thx for your reply :slight_smile: Also Pagespeed Insights gives me no hint to sprite my images … I will check with the guys there.
