Soft Rejection.Need help to resolve some of the issues

I submitted a coming soon template called langtang.and Reviewer pointed out some issues regrding the template.
Template Link:

1)RESPONSIVE ISSUES: Your files are either inaccurately represented as responsive or have responsive layout issues. Please take a moment to make sure that your design layout looks correct at different breakpoints and that all text is scaled appropriately for smaller devices. -->

I did find that there is a issue with textblock called “Our Website Is Under Construction.Subscribe To Be Notified.” and subscribe form not being properly aligned in mobile view.but i am not being able to find out the issue with social icon .In my browsers it is looking fine in both mac browsers and windows.

and this one too’t know in which browser it has the issue.

2)JQUERY PERFORMANCE: Your jQuery code can benefit from some performance tweaks. Please make sure that your jQuery is properly formatted, commented and that you are caching and chaining whenever possible. For more information please read:

Thanks.Any help would be appreciated.
