Blocs is a web design app that helps build websites without knowing how to write code. This new version 2.3.1 is built on its predecessor app, bringing more fresh features to the table. Custom class editing is perhaps the biggest and most welcome improvement in this version. The feature lets you create a fresh class, specify various CSS attributes, and apply them to any item across a website. Long story short, if you liked the earlier Blocs, but hoped a few things could get better, this new version has addressed those minor qualms.
