To make Elements more generic to handle we need to wrap them in a kind of container (or wrapper) – in MPS this is called a ‘Block’.
It’s in a way the less exciting pattern – but a very important one – as we are able to approach all the Elements in a more generic way. These are the building blocks of Partials and part of the MPS core.
Designers won’t notice any difference as a button will be a button – and are a part of the Principles phase.
For developers this pattern is more interesting as all the different HTML Elements can be accessed as a generic Block – they are part of the Model (library).
