1,736 PointsChecked VS Focus
Hey guys! I wonder what difference is there between :focus and :checked pseudo classes? As far as I understood :focus allows to modify appearance of an element that has been activated by a user (or simply clicked on). Seems like :checked does the same however is restricted to forms only.

Treehouse Teacher:checked
is for radio buttons and checkboxes
:focus
works with links, text form elements, select menus, text areas, buttons and any element with a tabindex
attribute. Try this little experiment
- Create a new web page and add a paragraph like this:
<p tabindex="1">
Then add this CSS:
p:focus { background-color: red; }
Preview the page in Chrome (not sure this works in ALL browsers) and press the tab button. The paragraph should turn red.
:active
applies to any tag that is clicked (but only when it's being clicked. Add this CSS to a page and click anywhere on the page:
:active { background-color: red; }

I believe that the :checked pseudo class is restricted to items that are "checkable".
e.g. checkboxes or radio buttons
So you are correct in how checked is restricted :)
