Link Hover Transparent for Activello WordPress theme

Hello again,

Still tweaking my design and I just noticed that links in the body of my posts have a hover effect of being highlighted in a box of my accent color. I’d love to have the hyperlink change color discretely instead of having that huge bold box of color. I attempted adding the following codes to my CSS, but nothing worked. Any suggestions?

a:focus {
  color: #FFFF;
  text-decoration: none;
a:hover {
  background-color: transparent;

Thank you!
