“If you just sit and observe, you will see how restless your mind is. If you try to calm it, it only makes it worse, but over time it does calm, and when it does, there’s room to hear more subtle things. You see so much more than you could see before. It’s a discipline; you have to practice it.”
Steve Jobs

counters()

The counters() CSS function enables nested counters, returning a concatenated string representing the current values of the named counters, if there are any. The counters() function has two forms: counters(name, string) or counters(name, string, style). It is generally used with pseudo-elements, but can be used, theoretically, anywhere a <string> value is supported. The generated text is the value of all counters with the given name, from outermost to innermost, separated by the specified string. The counters are rendered in the style indicated, defaulting to decimal if no style is specified.
