That doesn't actually work in pretty much any browser, since it allows for history-mining by a malicious site. :visited styling changed a couple of years ago to only honor color changes, thus preventing most ways of exploiting that issue.

http://dbaron.org/mozilla/visited-privacy is one of the better resources explaining the issue more fully.

I guess you could create the triangle solely with CSS borders, and then style the border-color to be the same color as the background when not :visited

There's eight links of "related content" underneath this article. Not all about this particular species, but pretty easy to filter through to see what's directly related:

In 2007, there were 14 of these rhinos left, 4 wild and 10 in captivity: http://www.theguardian.com/environment/2007/mar/04/conservat... - this article also cited a number of 30 back in 2000.

In October 2014, the second-to-last male died at the relatively young age of 34, leaving just 6 and removing the last realistic hope for breeding: http://www.theguardian.com/environment/2014/oct/18/northern-...

In December 2014, the next-to-last male died, of old age, leaving just 5: http://www.theguardian.com/environment/2014/dec/15/northern-...

It's painting a pretty dismal picture altogether. I guess conservation efforts were too little, too late, with the remaining population already too small and too aged to ever offer much hope for success. :(

My monitor brightness is indeed set very low (2/100), but increasing this to 100/100 doesn't change anything (nor does fiddling with the contrast). Don't think it's _purely_ a hardware problem anyway, since a regular terminal doesn't show it; only a terminal in which I'm running over SSH. Thanks for the suggestion, though!

With Fronteers (the Dutch trade organization for front-end web developers) we've been running a forum thread for such CSS logos for the last year and a half - http://forum.fronteers.nl/topic/24/the-css-challenge/ - conversation in Dutch, but the images and jsfiddle links should speak for themselves - and I personally think the chief benefit in this exercise comes from the process of _creating_ such a logo.

When you're looking at the end result, you might be mildly impressed by the versatility of CSS, or dismiss it as a rather pointless exercise for the real world (both of which are quite valid points of view), but when you're actually looking at a new logo and pondering how you'd approach the process of recreating it in pure CSS, you'll be triggered to dig deeper into CSS than you'd do during the ordinary course of web development work. The amount of value gained from that is hard to overstate.

I've recently been teaching someone completely new to web development the principles of HTML and CSS, and she's been picking it up pretty swiftly, but otherwise not doing much with it which was terribly noteworthy. Until I loosened restraints, and got her interested in just playing with some new techniques for the sake of playing (which included that CSS challenge). Suddenly she was doing things I'd never seen before, layering radial and linear gradients for some cool effects, transforming and animating the result, and just bringing it all together in wildly innovative ways. (It helps that she has no idea about the bad old days where we were all incredibly restrained by limited browser support.) :) For the CSS challenge she had a definite goal, and I could just see her conceptual thinking leaping ahead as she bounced ideas off of me on how to reach that goal. In the process of this all she discovered two browser bugs (will still get her to file them after making certain they won't be dupes), gained a much, much deeper understanding of the finer points of various CSS3 modules, and had her self-confidence boosted a lot by knowing that she could really figure out these things and create something which would've seemed like magic to her just weeks earlier.

I highly recommend any- and everyone to, when it's not immediately obvious how a particular logo was constructed, pick it apart and _see_ the way certain effects are combined. Expand your thinking. Yes, there's an obvious way to build up your basic CSS for a bread-and-butter website, which just works, and there's often not much challenge or versatility there (nor needed). But the techniques and capabilities at the forefront of CSS are changing and expanding rapidly, and more and more of these techniques do actually become quite applicable to ordinary websites. Not in the particular combinations found in a CSS logo, but still in forms which will bear an uncanny resemblance to them. Why not have some fun teaching yourself about them? It's good to every so often remind yourself that you're in a very creative field of work, which keeps changing rapidly.

Point. The equivalent dutch phrase didn't really have a good translation, and that sentence thus came our rather tortured. Let me see if I can make that a bit more palatable.

Edit: I turned it into "Fronteers is increasingly being looked at to provide best practices". It's still not quite what I meant to say, but comes closer.
