I'm facing a problem in css of the <a> element, This page is using Bootstrap Tab component. All tabs are connected with their corresponded links. By default css of the page has some base styles for <a> element i.e.
a {
    color: black;
}
a:hover {
    color: red;
}
On Tab there is ul element which has some links. I changed the color of links that are in ul element. But why hover color of the link is not changing to its base hover color? I only change the normal color not hover state color Why this happening?
