Are CSS reset pages (like this one) still necessary in today's age? I assume the answer is yes but looking to see if I get surprised.
I've read thoroughly the HTML5 BoilerPlate from Paul Irish but don't see myself adopting a standard that isn't necessarily standard. [Rhetorical] Isn't this at least some cause of what got us into this mess if you put aside the IE bashing?
Necessary? No.
Some developers like to use them, some don't, but they are definitely not necessary.
yes, the same reasons they were created still exist: several browsers have several different implementations of CSS, and this is one way to take care of them.
They are no less necessary than they ever were. IE6 still has a significant market share.
only if you want to have an easier time getting your site to look the same in all browsers.
If that is not a requirement, or if you don't mind having a hard time getting IE to follow suit then by all means. A lot of developers every day are making sites without css-resets.
