CSS Preprocessor Madness (LESS/SASS)

With the advent of CSS3, supporting multiple browser prefixes and layout versions for Responsive design can mean greater redundancy and more difficulty in terms of creation and maintenance. We’ll be giving an overview of the major CSS preprocessors, LESS, SASS/SCSS/Compass and possibly Stylus if we have time. We’ll also be discussing the pros and cons of each and the advantages and disadvantages of preprocessing either locally or server-side.

Fair warning: You should probably have a passing familiarity with CSS and best practices. If you don’t, this presentation may make your eyes glaze over instead of adding a sparkle to them. On the other hand, if you’re planning on getting started on CSS, this may be good to learn since understanding general preprocessing will probably be considered a core must-have skill in the near future. I’d just recommend jamming on the basics before you come.

I'm actually going to try to keep the actual presentation fairly short and do more hands on in two's or three's instead if possible. Ideally, I'd like people ready and able to go back to their teams and inspire them to apply these approaches to their current work right away!

We're happy to have the event hosted and sponsored once again at in downtown! Apologies to Westsiders once again. We tried to find a large venue that was free closer to that side of town. We'll keep looking for future meetups.


We will be raffling off two CSS books donated by

The Book of CSS3: A Developer's Guide to the Future of Web Design

Pro CSS for High Traffic Websites

Location has offered some great perks for this meet-up. First of all, they are providing access to their 44th floor dining and training rooms, which includes wifi access and projection screens. You’ll be impressed with the scenic views of the mountains and downtown LA. They will also be providing pizza and soft drinks and they even have a pool table, ping pong table and wii available for some added fun. They are located at 515 S. Flower St. on the 44th floor of the Paul Hastings Tower at City National Plaza in Downtown Los Angeles.

* You must bring a valid I.D. to check-in with the building security.


You’ll be happy to hear that is providing validation for parking at the LA Central Library parking garage at 524 S Flower Street lot across the street (first come, first served); it’s literally across the street from the office building. The rate after 4pm is $8 without validation. Also, here is a map of the meters and free spots after 6/7/8pm (please check all signs) -

*Note: Do Not Park in the City National Parking parking structure downstairs at 500 S. Flower St. There is no validation provided there and per hour is more expensive than parking at the Library.

    I've worked with SASS/SCSS before and it's great. What I'd like to do is learn from someone who's done LESS. Just as a request, if anyone's available. Thanks! :-)

    So I'm vaguely thinking on doing something like paired programming, where two or three people work on a computer and try to practice using LESS or SASS/SCSS in a hands on. This is why I ask what platform (OSX, Win, Linux) people use during the RSVP. SASS installation requires Ruby, which comes preinstalled on OSX but needs a manual install on Win 7. It's still not that difficult. Any interest?
