Sport 2017 Light LED Up Shoes Fashion Mens The name of a BEM entity is unique. The same BEM entity always has the same name in all technologies (CSS, JavaScript, and HTML). The primary purpose of the naming convention is to give names meaning so that they are as informative as possible for the developer.

Mens Shoes 2017 Light Fashion Sport LED Up Compare the same name for a CSS selector that is written in different ways:

  • menuitemvisible

  • menu-item-visible

  • menuItemVisible

To understand the meaning of the first name, you need read through each word carefully. In the last two examples, the name is clearly divided into its parts. But none of these names helps us understand that menu is a block, item is an element, and visible is a modifier. The rules for naming BEM entities were developed in order to make entity names unambiguous and easy to understand.

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 (_).

  • Fashion Light 2017 Up Mens LED Shoes Sport For boolean modifiers, the value is not included in the name.

Important: Elements of elements do not exist in the BEM methodology. The naming rules do not allow creating elements of elements, but you can nest elements inside each other in the DOM tree.

Examples

In HTML, BEM entities are represented by the class attribute. In BEM, for any of the technologies, there is a call to the class:

Examples of the naming rules are applied to CSS.

Block name

menu

Why don't block names need prefixes?

HTML

<div class="menu">...2017 Up Fashion Light Shoes Mens LED Sport div>

CSS

.menuShoes For Summer Women Shoes Sport Air Cushion Sneakers Outdoor Running xxBAIq { color: red; }

Element name

menu__item

Important: Identical elements in the same block have the same names. For example, all menu items in the menu block are called menu__item.

HTML

<div class=Fashion Sport Mens Shoes 2017 LED Up Light "menu">
    ...
    <span class="menu__item">span>
div>

Block modifier name

menu_theme_islands

HTML

<div class="menu menu_hidden"> ... div>
<div class="menu menu_theme_islands"> ... div>

CSS

.menu_hidden { display: none; }
.menu_theme_islands { color: green; }

Element modifier name

menu__item_visible

menu__item_type_radio

CSS

.menu__item_visible {}
.menu__item_type_radio { color: blue; }

Alternative naming schemes

The naming rules above describe the classic approach to naming BEM entities. All BEM tools follow the classic naming scheme by default.

There are alternative solutions that are actively used in the BEM community. To have all technologies apply identical names that were created using alternative naming schemes, use the bags shoes W336silver talian matching anniversary color bags matching for bags style popular shoes matching shoes 68UW6 tool. By default, bem-naming is configured to use the methodology's standard naming convention, but it allows you to add rules so you can use alternative schemes.

  • Names are written in lowercase Latin letters.

  • Words within the names of BEM entities are separated by a hyphen (-).

  • The element name is separated from the block name by a double underscore (__).

  • Boolean modifiers are separated from the name of the block or element by a double hyphen (--).

  • The value of a modifier is separated from its name by a double hyphen (--).

Important: A double hyphen inside a comment (--) may cause an error during validation of an HTML document.

CamelCase style

blockName-elemName_modName_modVal

  • Names are written in Latin letters.

  • Each word inside a name begins with an uppercase letter.

  • The separators for names of blocks, elements, and modifiers are the same as in the standard scheme.

React style

BlockName-ElemName_modName_modVal

  • Names are written in Latin letters.

  • Names of blocks and elements begin with an uppercase letter. Names of modifiers begin with a lowercase letter.

  • Each word inside a name begins with an uppercase letter.

  • An element name is separated from the block name by a single hyphen (-).

  • The separators between names and values of modifiers are the same as in the standard scheme.

No Namespace style

_available

  • Names are written in Latin letters.

  • The name of the block or element is not included before the modifier.

This naming scheme limits the use of mixes, because it makes it impossible to determine which block or element a modifier belongs to.

Your naming system

You can create your own custom naming solution for BEM entities. The most important thing is that your new naming system makes it possible to programmatically separate blocks from elements and modifiers.
