Guidelines

  • use rem instead of px

CSS naming

We use the BEM methodology.

Block

Standalone entity that is meaningful on its own.

Element

A part of a block that has no standalone meaning and is semantically tied to its block.

Modifier

A flag on a block or element. Use them to change appearance or behavior.

Naming rules

block-name__elem-name_mod-name_mod-val

  • Names are written in lowercase Latin letters.
  • Words are separated by a hyphen (-).
  • The block name defines the namespace for its elements and modifiers.
  • The element name is separated from the block name by a double underscore (__).
  • The modifier name is separated from the block or element name by a single underscore (_).
  • The modifier value is separated from the modifier name by a single underscore (_).
  • For boolean modifiers, the value is not included in the name.
