I wanna make the product thumbnails clickable.

Hello, HB Themes!
I have two problems working with the theme and wish you could help.

1. Making product thumbnails clickable.
When I put my mouse over product thumbnails, I see two buttons – ‘view details,’ and ‘add to cart’. Instead of having these buttons, I would like to have nothing showing up and make the thumbnail itself clickable.

2. Clicking images on mobile devices
When I visit my WordPress site on my mobile, I have a hard time clicking on any kind of images. Every time I click on an image, text box shows up. I can even type some letters, but I cannot actually see the letters though.

Thank you for reading, and I hope I can find some answers. Thank you.
