On the right, you can see image links to social networks. They are an html code inside a text widget. The problem is that awful black space/tab that you can see when the mouse goes over them.
How can I edit my style.css file in order to take it off from this widget only without taking off the effect in the other widgets (categories, archives, tags, etc.)?
I remember I followed some instruction in this forum but I couldn't solve the problem completely because the black background disappeared, but still there was a tiny red underline under the images.
I'm not an html/css expert, so please try to be very clear. Thank you.
