themia lite change sidebar width

Search for #sidebar in css and under that look for width.
Can you post your website?

Thanks for the reply ??
for example here:
https://www.lauralempert.com.ar/?p=4
the video doesn′t appear complete because the main area is too small.. so is it possible to either make the sidebar take less space.. or make the whole thing bigger so the videos aren′t cut?

Also, here in the main blog:
https://www.lauralempert.com.ar/?page_id=244
I′d like to have it work so the videos show there, not having to click on “Continue reading” is that possible?
