# Class-naming Convention

In plain words

The naming system a developer uses to organize and label the styles across a website. A solid system — like Lumos — keeps a site maintainable long-term. The absence of one is a sign of future technical debt.

Example

Classes like card\_title and card\_title--large make it clear what each style does, so another developer can edit the site without breaking the layout.
