HTML5 Slide Template

Configuring the slides

Much of the deck is customized by changing the settings in slide_config.js. Some of the customizations include the title, Analytics tracking ID, speaker information (name, social urls, blog), web fonts to load, themes, and other general behavior.

Customizing the #io12 hash

The bottom of the slides include #io12 by default. If you’d like to change this, please update the variable $social-tags: '#io12'; in /theme/scss/default.scss.

See the next section on “Editing CSS” before you go editing things.

Editing CSS

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 (see /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.

Installing Compass and making changes

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 /theme/scss 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 /theme/css. Slick.

By default, 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 _base.scss.

Running the slides

The slides can be run locally from file:// making development easy :)

Running from a web server

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 http://localhost:8000/template.html:

$ cd io-2012-slides
$ ./serve.sh

You can also specify a custom port:

$ ./serve.sh 8080

Presenter mode

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.
