[color=#000000ost_uid0]Eventually MathML will come standard in all browsers and then you can make complex mathematical notations in a browser easily.

For example, sqrt(12345) would be expressed:

[bost_uid0]HTML[/bost_uid0]

[color=#333333ost_uid0]$$ 12345 [/colorost_uid0]

But currently most browsers (and webpages) aren't designed for it, so for now we have to resort to CSS tricks. (By the way, I think overline looked the best of all the examples so far.)[/colorost_uid0]
