yeah, mostly for the design part and CSS quirks among browsers. I do want to start with just sass and flexbox only though, but don't know how much hassle it will be.

Thanks for mentioning BEM, do you use it with sass?

I use SASS mixins specifically instead of BEM: this keeps styling out of my HTML (no visual classes to change) at the expense of a few bytes.
