Here's my portfolio, created as Udacity's "Frontend Developer Nanodegree" project and then improved little by little. I've used my HTML and CSS skills to build a full responsive website
This portfolio is 100% responisve for all the devices. There are major and minor breakpoint for 4 main screen sizes:
- smartphone
- phablet
- tablet
- desktop
The layout grid is made with flexbox and I've used "scrset" to render different images for different viewport width.
