Rules related to checking the compatability of the CSS on the page ensuring the stylesheet works on older browsers too

Having an outline is important for accessibility. Without this certain users will never know which elements has focus. 

Taking this away because of ill-conceived aesthetics is bad.

# How to Fix
Do not remove the outline, but if you really have to you could modify it.

```css
/* BAD */
a:focus {
  border: 1px solid red;
  outline: none;
}

/* GOOD */
a:focus {
  border: 1px solid red;
  outline: 2px solid red;
}
```
