Bevels in CSS3

Yeah, yeah I know, bevels are soooo 1996. And I agree. However, it’s always good to know the capabilities of your tools. Talented designers will know when it’s suitable to use a certain effect and incapable ones will abuse whatever is given to them, so after a lot of thought, I decided to blog about my discovery.

CSS3 colors, today (MediaCampAthens session)

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 πŸ˜› . This caused some goofs:

  • When introducing myself, I said completely different things than I intended to and ended up sounding like an arrogant moron πŸ˜›
  • I tried not to look at the audience too much, in order to avoid sounding nervous, and this caused me to completely ignore 2 questions (as I found out afterwards)! How embarrasing!
  • At a certain point, I said “URL” instead of “domain” πŸ˜›

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 πŸ˜› ).

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 πŸ˜›

CMYK colors in CSS: Useful or useless?

As someone who dealed a bit with print design in the past, I consider CMYK colors the easiest color system for humen to understand and manipulate. It’s very similar to what we used as children, when mixing watercolors for our drawings. It makes perfect sense, more than HSL and definately more than RGB. I understand that most of us are so accustomed to using RGB that can’t realise that, but try to think for a moment: Which color system would make more sense to you if you had no idea and no experience at all with any of them?

Check whether the browser supports RGBA (and other CSS3 values)

When using CSS, we can just include both declarations, one using rgba, and one without it, as mentioned in my post on cross-browser RGBA backgrounds. When writing JavaScript however, it’s a waste of resources to do that (and requires more verbose code), since we can easily check whether the browser is RGBA-capable, almost as easily as we can check whether it suppports a given property. We can even follow the same technique to detect the support of other CSS3 values (for instance, multiple backgrounds support, HSLA support, etc).

Bulletproof, cross-browser RGBA backgrounds, today

UPDATE: New version

First of all, happy Valentine’s day for yersterday. πŸ™‚ 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.

CSS3 border-radius, today

This is the first one from a series of articles I’m going to write about using CSS3 properties or values today. I’ll cover everything I have found out while using them, including various browser quirks and bugs I know of or have personally filed regarding them. In this part I’ll discuss ways to create rounded corners without images and if possible without JavaScript in the most cross-browser fashion.
