Social icons and shopping card icon not aligned properly for a mobile browser. I’d like to modify it.
Is this your URL? http://ellero.com/ (Summer2016)
Please tell us how you want to align the icons. I will try and see if it’s possible.
How can I add additional button to the header and re-arrange current icons for the mobile browser?
This requires modifying theme codes, which is not cover in our support scope.
You can open up social-buttons.php and add HTML code after the PHP foreach loop, or contact our developers for this customization. https://theme4press.com/theme-customization-service/
Which file is responsible for generating header on mobile browser?
No special mobile browser header file, only header file and they are located in evolve-plus/template/header_v… depending on which header you selected in theme options.
