Note from student

This submission works straight out of the box - no need to run gulp first.

To view the first part of the assignement:

Clone repo
Open index.html

To view the second part:

Navigate to the 'views' folder
Open pizza.html

I used gulp to optimise the html, css and images. However I did so without using dev and dist folders.

Original readme content follows:

Website Performance Optimization portfolio project

Your challenge, if you wish to accept it (and we sure hope you will), is to optimize this online portfolio for speed! In particular, optimize the critical rendering path and make this page render as quickly as possible by applying the techniques you've picked up in the Critical Rendering Path course.

To get started, check out the repository and inspect the code.

Getting started

####Part 1: Optimize PageSpeed Insights score for index.html

Some useful tips to help you get started:

Check out the repository
To inspect the site on your phone, you can run a local server

$> cd /path/to/your-project-folder
$> python -m SimpleHTTPServer 8080

Open a browser and visit localhost:8080
Download and install ngrok to the top-level of your project directory to make your local server accessible remotely.

$> cd /path/to/your-project-folder
$> ./ngrok http 8080

Copy the public URL ngrok gives you and try running it through PageSpeed Insights! Optional: More on integrating ngrok, Grunt and PageSpeed.

Profile, optimize, measure... and then lather, rinse, and repeat. Good luck!

####Part 2: Optimize Frames per Second in pizza.html

To optimize views/pizza.html, you will need to modify views/js/main.js until your frames per second rate is 60 fps or higher. You will find instructive comments in main.js.

You might find the FPS Counter/HUD Display useful in Chrome developer tools described here: Chrome Dev Tools tips-and-tricks.

Customization with Bootstrap

The portfolio was built on Twitter's Bootstrap framework. All custom styles are in dist/css/portfolio.css in the portfolio repo.
