Exclude children from :nth-child(n) / only include certain children<p>Is it possible to only select certain children?

<p>Key repeat is usually handled at the operating system level, and can be set by the user, so your code shouldn't rely on it happening at any particular speed.</p> <p>If you're okay with that, go ahead and use the OS-defined (and/or user-defined) key repeat.</p> <p>If you aren't, though, you can easily set up your own...
