Much of the deck is customized by changing the settings in
Some of the customizations include the title, Analytics tracking ID, speaker
information (name, social urls, blog), web fonts to load, themes, and other
The bottom of the slides include
#io12 by default. If you'd like to change
this, please update the variable
$social-tags: '#io12'; in
See the next section on "Editing CSS" before you go editing things.
Compass is a CSS preprocessor used to compile SCSS/SASS into CSS. We chose SCSS for the new slide deck for maintainability, easier browser compatibility, and because...it's the future!
That said, if not comfortable working with SCSS or don't want to learn something
new, not a problem. The generated .css files can already be found in
/theme/css). You can just edit those and bypass SCSS altogether.
However, our recommendation is to use Compass. It's super easy to install and use.
First, install compass:
sudo gem update --system sudo gem install compass
Next, you'll want to watch for changes to the exiting .scss files in
and any new one you add:
$ cd io-2012-slides $ compass watch
This command automatically recompiles the .scss file when you make a change.
Its corresponding .css file is output to
config.rb in the main project folder outputs minified
.css. It's a best practice after all! However, if you want unminified files,
run watch with the style output flag:
compass watch -s expanded
Note: You should not need to edit
The slides can be run locally from
file:// making development easy :)
If at some point you should need a web server, use
serve.sh. It will
launch a simple one and point your default browser to
$ cd io-2012-slides $ ./serve.sh
You can also specify a custom port:
$ ./serve.sh 8080
The slides contain a presenter mode feature (beta) to view + control the slides from a popup window.
To enable presenter mode, add
presentme=true to the URL: http://localhost:8000/template.html?presentme=true
To disable presenter mode, hit http://localhost:8000/template.html?presentme=false
Presenter mode is sticky, so refreshing the page will persist your settings.
