These little buttons were popular on blogs in the early 2000s. Often they were used to inform the website visitor of the blogger’s tech-saviness; that the website’s HTML code was “valid”.
The first known ‘Antipixel’ buttons originate from a blog of the same name. There was also a huge collection on George Taylor’s website. You can also find an archive on Príomh Ó hÚigínn’s Dribbble account.
They may have gone out of fashion, but I still think they’re cool.
Below are some I’ve made. Feel free to steal them, recolour them, edit them. I don’t mind.
I have one simple ask: Don’t hotlink. That means don’t link the image source to pathtoharmony.net, but rather upload to your own image storage. (Upload to something like Imgur if you must.)
