For reasons that have always escaped me, web designers nowadays prefer
to write several versions of their code, each custom-tailored to one of
their favorite (familiar) browsers, instead of writing one W3C-compliant
version that works on all browsers. Then in order to make this
needlessly cumbersome system work, they have to "sniff" the browser (ask
it what it is) and then serve the appropriate version (if it's one of
the approved browsers) or an error message (if it's not).
I think it was in the olden days that web designers wrote several
versions of their code tailored to a favorite browser, and it is an old
habit that was passed on to new designers.
Standards compliant versions should work in any browser that supports
those standards and the new web technology.
