They became small again when i refresh my site (sometimes after 1 refresh, sometimes afret few). Do someone has this issue and find the solution? Please help.

ZenCart does not function correctly inside of a frame...
Why have you placed it inside of a frame?

The hosting company put it in the frame, but when I go to my site with the direct link to index page, the problem stay's in.

Your host does not know ZenCart very well
It is in a frame!!!
What direct link?

When using this link, site is no longer in the frame.

Looking at this in Firefox and IE6 I do not see what you describe??
What browser are you using?
I do see in IE6 that you have several broken image links

I use FF 3.0 (3 different versions, 3 different computers). Everywhere problem is the same. Quickest way to see the problem is choosing "wyprzedaże" and from there view some products.

Still do not see issue - all text size stays constant for me
Maybe another will be able to view the issue??

The problem really is not in my head :)

I still do not see where these change???

But add this to your stylesheet.css file and adjust to suit

h3.itemTitle a:link {
        font-size: 1em;
        font-weight: normal;
        }

For example: in good image categorie "wyprzedaże" looks fine, but in bad image this categorie do not fit to the "kategorie" frame

adding this code to stylesheet did not help't

The additional code is NOT in your stylesheet
Are you sure that you added it to the correct location?

If templates/classic/css is the right location than yes
I added it here:

h3 {
font-size: 1.3em;
}

h3.itemTitle a:link {
font-size: 1em;
font-weight: normal;
}

h4, h5, h6, LABEL, h4.optionName, LEGEND, ADDRESS, .sideBoxContent, .larger{
font-size: 1.3em;
}

If templates/classic/css is the right location than yes
That is the template and stylesheet that you are using BUT the code addition is not there
Using FTP - you have this stylesheet edited and on your local PC correct??

Then first delete the one on the server and upload the edited one from your local

Yes, I uploaded this file to the server. I'm thinking now if this could be problem with text encoding? MySQL base is set to utf8_unicode_ci, and the language file "UTF-8", maybe that is it?

Try downloading the copy on the server to another local location and open it and search for the addition

This is a file and not a mysql encoding issue

What editor are you using for file edits?

I rewrite it (i view file with winscp(ftp client) - the file on server has changed to file with addiction).

I'm using notepad pro with text encoding set to UTF-8.

Maybe zencart has problem with utf-8?
