Hi,
1/ To do that, please add more this code to Customize > Custom CSS:
\\
@media only screen and (max-width: 1170px){\
.container.penci_sidebar #main{ width: 75%; }\
.penci-sidebar-content{ width: 25%; }\
}\
Change number 25 & 75 on the above code to value you want. Make sure total of this 2 values is 100.
\Example: 24% and 76%
2/ You just need use smaller images and re-upload to your about me image.
You can use this site to crop/resize image before upload it to your site.
\Best Regards,
