Hello,
0) I have edited the first section of the Download page on the EN version of your site. Check now if this is suitable for you. If yes then I’ll be able to finish all the other sections on the page.
1) Edit pages and check the full-width option to make it 100% with also for the mobile device https://prnt.sc/QKh4_eccEAGM
Or add the below code to Theme Options > Custom CSS to make it full-width for the mobile device only
@media only screen and (max-width:480px){
.mpc-lightbox .mpc-button, .mpc-lightbox {width: 100%;}
}
Waiting for your reply.
Regards
