hi all. probably a trifle put google didn't tell me much. I notice
there are size units such as 'pt' and 'px'. is there one that will
position the same regardless of browser size, screen resolution,
browser type?
Basically, no.
Read
http://www.w3.org/TR/CSS21/syndata.html#length-units for the
descriptions of all the different units.
In theory, if you use an absolute unit (in, cm, mm, pt or pc) it should
display the same size on all devices (although that may be a varying number
of physical pixels as resolution varies), but in practice different
browsers have different interpretations, and fixed sizes are pretty
unfriendly as far as accessibility is concerned.
Even if you think you have tied the sizes down pretty tightly (e.g. width
and font size specified in pixels) you will still find that text
displays at different sizes in different browsers and wraps differently on
different devices in the same browser.
The best thing is to make your layouts flexible so that they display well
over a wide range of conditions (and test over a wide range of systems as
well).
