Hi,
I am relatively new to the area, and still trying to sort out some
concepts .. any help would be appreciated.
CSS BROWSER SUPPORT
-------------------------------------
>From this site,
http://www.webreview.com/style/css1/charts/mastergrid.shtml
it would appear that 'most' CSS1 features are supported by Navigator 4.6
and above and anything above IE4 looks fairly safe. It also says, in the
FAQ that Navigator 3 has no CSS support.
As a broad statement, would it be fair to say that I should have
relatively few difficulties with a conservative usage of CSS1 - is it
reasonable to assume that the vast majority of browsers out there are at
NN4.6 and above or IE4 and above?
now, wrt CSS2 , it seems that Navigator4.6 and IE 4 are about on a par,
but that you really need to got to Navigator6 or IE5 or above for a fuller
implementation of CSS2.
I am interested in pagination support, but I don't know enough yet about
paged media CSS features to be able to figure out whether the CSS2
implementation table at
http://www.webreview.com/style/css2/charts/selectors.shtml
tells me which browsers support it.
Can anyone enlighten me?
Finally a dumb/newbie question on CSS. Is a CSS always 'safe'? as in, if
a page with a modern CSS is viewed in an older browser, will it look OK ..
as in, will the newer features be simply ignored. Or should I really think
about browser specific style sheets, and include them appropriately (I
don't even know if this is feasible).
DHTML
---------
I am really lost here. There are a couple of really basic things I don't
understand
a) is DHTML a Microsoft only gizmo? I went to W3C and saw no obvious
mention of it, but a search from the w3c site revealed various
newsgroup/email messages talking about it. So if I use DHTML, and it is
Microsoft specific, what happens in Netscape etc. Similar questions re
older browsers as for CSS.
b) why do I need it? in my brief acquaintance with it, it seems like
rebranded javascript. Or am I being more than usually obtuse.
Any comments, pointers to RTFM, elucidation of concepts .. would be
gratefully received.
Thanks
John Aitchison
