Attribute to compression

[irl]

There's a fascinating menu when we put a mouse on the element, it works attribute, hover, when we click on the element of the rolling list works:focus. I'm telling the border, none of it, but I see the blue frame when it's clicked like a slide menu and one of the list points:

I've already written in styles wherever the border can be:none;

.dropdown-menu li a:focus{
background: transparent ;
color: red ;
}
.dropdown-menu li :focus{
background: transparent ;
color: red ;
border: none;
}
.dropdown-menu :focus{
background: transparent ;
color: red ;
border: none;
} 

The color of the adjective changes to the red and the border does not disappear:D

This thing is called outline♪ Just add the following line to the style.

outline:0;
