Use btn-primary for the Save button

[scharf]

The save button is not an informational alert message but rather ... a successful or positive action. This can confuse users.

See the bootstrap documentation for the button classes:

<!-- Indicates a successful or positive action -->
<button type="button" class="btn btn-success">Success</button>

<!-- Contextual button for informational alert messages -->
<button type="button" class="btn btn-info">Info</button>

Hmm, maybe btn-primary is even a better choice for this button, because this is the primary action....

<!-- Provides extra visual weight and identifies the primary action in a set of buttons -->
<button type="button" class="btn btn-primary">Primary</button>
