CSS Preprocessors (SASS/LESS) with Jonathan Verrecchia
- May 31, 2012 · 6:30 PM
About the Talk
During this talk, Jonathan Verrecchia (@verekia) will demonstrate the power of CSS preprocessors and explain why he believes these are a game changer for front-end development.
CSS preprocessors are used to enhance CSS with amazing new features (variables, functions, file concatenation and minification, color operations, etc.) and can dramatically improve your development workflow. Jonathan will shed light on some very common misconceptions about them and will help you understand how choose between SASS, LESS and Stylus for your next project.
The talk will cover the basics of CSS preprocessors but also more advanced techniques with concrete use cases. If you haven’t dived into CSS preprocessors yet, if you’re still skeptical, or if you want one more proof that they’re the way to go now, this talk is for you!

It was a good talk but I was expecting to learn some reasons that CSS pre-processors are significantly better than simply writing CSS files as server-side scripts in PHP or some other language. Unfortunately I didn't hear any reasons convincing enough to make me change to any pre-processor. Sure, a pre-processor can do a few things a little cleaner and may have some slick functions, but it can never be as flexible and extensible as your own code. Using a pre-processor changes work-flow and is yet another language to learn. On the other hand, using your favorite server-side scripting language such as PHP means you just write using the same language you usually use, and simply create variables and macros and write functions to do what you need to do to produce the stylesheet you want. And you don't have to worry about forgetting to run the pre-processor.

It is a very informative talk, it covers a broad range of topics in using CSS Preprocessors. The speaker is very good and clear in dividing the topics to make things easy to follow. It was also entertaining. I got some good tips from it. The part where OOCSS was discussed was a surprise to me, and I definitely enjoy the insight he provided, because it is very relevant to me. But I did expect a bit more in dept discussion on best practices and approaches, such as strategy on using version control and preprocessors.

Jonathan gave an excellent presentation. He obviously put a huge amount of work into his talk and i also appreciated his humor. I may try to incorporate SASS into some personal projects to experiment. I have been using php to include variables in my css files, and i am still confused as to why variables are not part of the css3 spec. I think these should be normal features you do with css, and you should not need to install separate things to output back to "normal" css.

I thought the presentation was very useful. I don't yet use preprocessors so it was at the right level of detail to provide a decent introduction.
