Anyone viewing this site from Internet Explorer on Windows will have noticed that the logo in the top left seemed to have a grey background rather than being the same colour as the rest of the page. This didn’t happen on other browsers, because Internet Explorer is the only modern, graphical, browser that doesn’t support transparency in PNGs.
Those of you that develop your own web pages may say, at this point, well, that’s not hard to fix, however the solutions that are out there at the moment deal with
<img> tags, whereas the logo on this site is done using a
background-image: setting on the CSS
If only Microsoft would fix its broken browser. Their Mac team did it, because transparent PNGs work fine on the Mac version of Internet Explorer, but, sadly, the PC version still isn’t fixed.
