To remove all doted outline, including those in bootstrap themes.

a, a:active, a:focus, 
button, button:focus, button:active, 
.btn, .btn:focus, .btn:active:focus, .btn.active:focus, .btn.focus, .btn.focus:active, .btn.active.focus {
    outline: none;

}

input::-moz-focus-inner {

}

Note: You should add link href for bootstrap css before the main css, so bootstrap doesn't override your style.
