Custom styling individual letters
<p>I wanted to ask, if there is a way to style clean way ( without using for example <code>&lt;span&gt;&lt;/span&gt;</code> ) for each sign, numbers ?</p>

<p>In attachment some example. We can see, let's say "flip clock" effect.</p>

<p>I found some plugins as flipclock, but i don't need any JS for animations, etc...</p>

<p>I just need to style number, by adding some background to every sign...</p>
