Remove outlines globally

Some elements like textarea and button are using outline as default. Do you reset them everytime you see them? It's possible to do that globally.

:focus {
  outline: 0;
}

HTML

<textarea></textarea>

Implement an alternative

To remove the outline on all elements may not be a good thing on mobile devices, unless you implement an alternative like below.

textarea:focus {
  background: #eee;
}
