Hello!
I wanto make k2.css lighter 
in k2.css file there are some empty {} (196 occurrences) that could be deleted if i dont want to style it, right?

I can delete it without problems? Can I delete also the lines that have those empty {}?

And, if I can do it, must I delete also references in php files? 

thanks

Hi..
Why not just break up your k2.css file into multiple small one.
e.g:
k2.css @importa the following
k2comment.css
k2latestitems.css
k2categories.css
....
it works fine, load smooth and quick for me.

if I can do it, must I delete also references in php files?
sorry for the question

no. If you delete the style and the references from the html is still there the only thing that happens is that the html fragment isn't styled.

thank you,
with a template like quasar that load a huge quantity of css i need to break them until my site goes fastly

can you suggest me some other tricks to make it fastly?

I would consider trimming the css that is not needed in Quasar.
How many css files does it ship with, how many of the style variations do you need to use?

Both Troponin and Followeyes, hi guys, offer valid advise.
If you remove any css element or file, it will just use defaults set by Joomla or not appear correctly.
Remove any classes with {}.

There will also be some instances, where several classes use the same setting so they can be joined together.

Consider also, do you use the gzip functions in Joomla?

Also, the css will be a part of the factor of speed, you will also need to consider how many scripts are being loaded and the qty and size of images too.

You can use a css compressor (there are several in web) but be patient that they dont destroy your css (backup).
Another way would be to compress it with ob_gzhandler.

Never used something like this, so take care.
