Any feedback you can give would be appreciated ;)

Blaze doesn't mention Bootstrap specifically regards opt in. But Bootstrap does apply CSS to some elements without permission. Foundation even more so. SemanticUI too. Blaze is different than all of these in that it gives the power back to you!

Only what I addressed. Typography, which you can disable or override easily.

Let's be clear, Bootstrap is the most popular CSS framework in the world, whose Github issue threads have been pored over many times more than Blaze's are likely to be for a very long time, and Bootstrap 3 at least never took any power away.

There are some really cool looking elements to Blaze and I'm very interested in using it for some upcoming projects, but to infer that you should ditch Bootstrap for it, on the basis of opt-in vs opt-out is very misleading.

Fixed ;)

Mentioned above: It's un-opinionated as in styling is drawn back but not to the point of it being ugly. Look at a Blaze site and it doesn't look like a Blaze site. Everyone can tell when a site has been Bootstrapped. It's aiming for an un-opinionated solution rather than source code

Single Reaponsibility principal. Create a class called .button. The responsibility of that class is to define what a button looks like. Then create a class called .button--primary whose sole responsibility is to define what a primary button looks like. If you create a class called .primary it has multiple responsibilities spread over the solution making it harder to maintain and improve upon

Could raise an issue in the repo if it's still a problem?

Thanks! Worked hard on the grid!

From my experience this is a non-issue in the OSS environment, you got to pick your frameworks based on other criteria; popularity, fit for purpose, community engagement, learning curve to maintain yourself etc. All of which has nothing to do with company or individual ownership. Blaze benefits from an MIT licence so it's totally accessible
