Arrow and close button underline issue with Jasper template

Hello Squarespace Forum, 

Going straight to the business: 

Have been using Japer theme for a while and recently realised the 'previous' and 'next' arrow in the gallery slideshow gets underlined when the mouse cursor hovers over it. The same applies to the 'close' button - have been trying to change it in Site Styles without any luck, so decided to email customer support and suggested creating a thread here.

Can anybody advise how I can disable the underline effect for both 'previous' & 'next' arrows and  'close' button? Would imagine we are talking custom CSS here...

Best Wishes, 

Darek

    border: none !important;
    background: none !important;
    text-decoration: none !important;
}
