use CSS to add line numbers?

[evanwill]

something like:

<style> 
    body { counter-reset: section; }
    #contents-container .textline::before {
        counter-increment: section;
        content: counter(section);
    }
</style> 

The count is auto generated by counting some element selector, so would need to tweak which container it is counting to get line numbers that match what we want.

advantage = when you select text, you don't get the line numbers (is this good?). might simplify markup and layout and getting auto numbered lines for display.

disadvantage = potentially doesn't correspond to line # as listed in csv. However, that might get confusing in the text display if the line numbers are off in the csv in general anyway.
