Today I needed to quickly find the Gravatars that corresponded to a bunch of email addresses for some reason (don’t ask). After a bit of googling and wandering around in Gravatar’s official site and others, I firgured out it’s probably much quicker to write a short PHP script for that myself, than keep looking.
Here it is, in case someone ever needs to do something similar: (click on the screenshot)

It’s been a while since I posted my little server-side solution for cross-browser RGBA colors (in a nutshell: native rgba for the cool browsers that support it, a PHP-generated image for those that don’t). For features, advantages, disadvantages etc, go see the original post. In this one I’ll only discuss the new version.
So, since it’s release I’ve received suggestions from many people regarding this script. Some other ideas were gathered during troubleshooting issues that some others faced while trying to use it. I hope I didn’t forget anything/anyone

Yesterday, I had a session at MediaCampAthens (a BarCamp-style event), regarding CSS3 colors. If you’ve followed my earlier posts tagged with “colors”, my presentation was mostly a sum-up of these.
It was my first presentation ever, actually, the first time I talked to an audience for more than 1 minute . This caused some goofs:
Also, I had prepared some screenshots (you’ll see them in the ppt) and the projector completely screwed them up, as it showed any dark color as black.
Apart from those, I think it went very well, I received lots of positive feedback about it and the audience was paying attention, so I guess they found it interesting (something that I didn’t expect ).
Here is the presentation:
Please note that Slideshare messed up slide #8 and the background seems semi-transparent grey instead of semi-transparent white.
By the way, I also thought afterwards that I had made a mistake: -ms-filter is not required if we combine the gradient filter with Data URIs, since IE8 supports Data URIs (for images at least). Oops, I hate making mistakes that I can’t correct.
Here are some photos from my session. If I did it correctly, every facebook user can see them. If I messed things up, tell me
First of all, happy Valentine’s day for yersterday. This is the second part of my “Using CSS3 today” series. This article discusses current RGBA browser support and ways to use RGBA backgrounds in non-supporting browsers. Bonus gift: A PHP script of mine that creates fallback 1-pixel images on the fly that allow you to easily utilize RGBA backgrounds in any browser that can support png transparency. In addition, the images created are forced to be cached by the client and they are saved on the server’s hard drive for higher performance. (more…)
