Despite anchor tags having
HREF attributes which lead to other host names, browsers do not execute DNS lookups on those domains. Content prefetching can be invaluable in speeding up your websites, but did you know that you can also implement DNS prefetching? It's as easy as simple
<link rel="dns-prefetch" href="//somehost.tld" />
This technique can be very useful when your website links to related host names. Take Twitter for example; they implement two DNS prefetches:
<link rel="dns-prefetch" href="https://si0.twimg.com" />
<link rel="dns-prefetch" href="https://api.twitter.com" />
I'd be willing to bet that most of you didn't know this tag existed. It's an interesting idea with a very simple execution. What do you think? Do you manage websites that prefetching could be helpful for?

I spent a few months experimenting with different approaches for writing simple, elegant and maintainable media queries with Sass. Each solution had something that I really liked, but I couldn't find one that covered everything I needed to do, so I ventured into creating my...
With CSS border-radius, I showed you how CSS can bridge the gap between design and development by adding rounded corners to elements. CSS gradients are another step in that direction. Now that CSS gradients are supported in Internet Explorer 8+, Firefox, Safari, and Chrome...
Without a doubt, my least favorite form element is the
SELECT element. The element is almost unstylable, looks different across platforms, has had inconsistent value access, and disaster that is the result of
multiple=true is, well, a disaster. Needless to say, whenever a developer goes...
