+ 1 comment This is my solution in python but it failed test case 3, it happens for a bigger a number of input because of time out.
if name == 'main': t = int(input().strip()) for t_itr in range(t): n = int(input().strip()) fib1 = 0 fib2 = 1 count = 0 inp = 10000 num = set() num2 = set() while count < inp: if fib1 < n and fib1 % 2 == 0: num.add(fib1) fib3 = fib2+fib1 fib1, fib2 = fib2, fib3 count += 1 print(sum(num))

The browser is smart enough not to load that CSS file at all (unless you’re printing, natch).
You can also do this:
Butttttt, the browser will actually load both of those files regardless if the media matches or not. So no obvious immediate benefit, but that’s where Vadim’s research comes in. While all the files with non-matching media (queries) still load, the browser is smart enough to make the non-matching stylesheets load with a lower priority. At least in Chrome and Firefox — Safari has some bug that makes the priority levels not provide the perf benefits.
Pretty cool I think. Doing this kind of work by hand feels onerous though, I’d love to see build processes deal with it automatically.
Ya know I was scared for Mozilla & Firefox for a while. Those big layoffs in 2020 included many browser engine engineers and it seemed like it would be hard to continue to be a viable browser engine alternative without a strong team there. But I was essentially wrong. Since then they’ve shipped plenty of important web platform features at a decent pace, including the ever-important Container Queries and new color formats. Putting MDN on GitHub happened after the layoffs too and that seems like a massive thing to get shipped.
Last year WIRED asked Is Firefox OK? There wasn’t really an answer there, but some good information. We know Google provides the bulk of their income, but they showed really strong growth with their own products and services, saying 14% of all revenue was that back in 2021. They’ve clearly been trying new stuff to increase that, so things look on the right track to me.
I like to see little stories like this: Mozilla fixed an 18-year old CSS bug in the Firefox browser. So they aren’t just playing catch up, they are getting details right along the way too. Better late than never. This one was a weird bug with ::first-letter, the real ticket for doing drop caps:
examples of the first-letter CSS property in very old versions of the Firefox browser. They said it was kind of a bandaid for now but still cool. Speaking of drop caps though… ::first-letter was always fraught for this purpose. Much better would be to support initial-letter. C’mon Firefox, you can do it!
