After few recommendations, theme is finally changed to a child theme of Spacious. It is very light and responsive which makes it ideal for mobile devices. Also, I have decided to go with a dark theme this time. Slider with the applications is removed but I will add them as links to the sidebar by the end of the day. Website is tested also by Google bots and they found it mobile friendly. If you have any comments on how it can be improved let me know. Enjoy the refreshed website.
