Remove light blue outline from Add to Cart hover

I've put in my own custom CSS for the Add to Cart button, but on hover there is always a 2px light blue outline around the button when I hover over it. How do I get rid of it? I tried adjusting the border, but the border shows up within the light blue outline.

See here: alcachofa

Currently, it is set to have a 2px black border on hover.

Thank you~

You need to go in the config under the tab display and edit the front end CSS file to remove the code below if you want to remove the blue outline from the button :

a.hikashop_cart_button:hover {
outline: 2px solid #92C1FF;
}

Thank you!
