There is an issue with the hover effect that only appears on Safari 10.0.
The web is this: Manu Caballero
What is happening is that the effect is working radomly, or not working at all:
To see it working, you can use Chrome or Firefox.
The most strange thing is that, on Safari 10.0, if I try to use the inspector, the hover effect works...
On Safari 10.1 and other common browsers like Chrome, Firefox... is working perfectly.
