Wanted to ask a question, about how to add custom code to css to get alternating colors in table rows, but I think I found an answer myself, by adding this code to the custom css in the J51 Classic template. Or do you suggest another solution? (This seems to work).

tr:nth-child(odd) { background-color:#eee; }
tr:nth-child(even) { background-color:#fff; }

However, one other question. If I want to change the H1 font/size (and for that matter the other H-tags as well), I can't seem to do it in the template itself (when I change the font to i.e. Economica, it only works on H2, not on H1 - and the font size becomes way too big). Which css-style sheet do I need to open, to change it throughout the site, as I found multiple style sheets.

Thanks in advance for your support.
