Informations about the package bem
BEM
BEM — is a methodology that helps you to create reusable components and code sharing in front‑end development
Usage
Create a class instance to represent your BEM model. Pass the "block" as the constructor argument.
All methods return an object instance that can be typecast to a string. Or, you can also call toString()
or toArray()
as appropriate; see \AKlump\Bem\Fluent\Interfaces\OutputInterface
for details. All of the following produce the same output.
For simplicity any remaining examples will show only the first form.

Convenience Syntax
There are some conveniences you should take note of; pay special attention to the plus*
methods.
"Global" Innovation
You'll find an innovation in this project called global. It can be used to target common parts across all blocks at once. Refer to the example below where component
and component__content
represent the global block and global element, respectively. This innovation, in this case, allows you to target all three components' content
in a single line of CSS. It can be thought of as a means of grouping. Use the the plusGlobal()
method for this feature.
Casting to Array
Given a complex chain as shown next, you can see the helpfulness of the plus*
methods and why you might want to use the toArray()
method.
Customizing Output Style
To alter the way the classes are formatted, create a new, custom class implementing \AKlump\Bem\Styles\StyleInterface
for control of the processing and output of the classes, including the division characters. Look to \AKlump\Bem\Styles\Official
for a model. Pass your custom style to \AKlump\Bem\Fluent\Bem
when constructing.
