Hi! It is similar, though obviously has a lot less functionality than, say, Bootstrap. We built it so we could control what we need/when we need it, to keep things as small and lean as possible! Thanks for posting this on Product Hunt!

CSS frameworks are all the rage these days. Between Zurb's Foundation new v.6, Bootstrap upcoming v.4 and now this, there's a lot to choose from. Solid does look fairly similar to the other two though. It would be interesting to hear the developers' thoughts.
