CSS Classes

YetaWF uses numerous CSS classes and follows a strict naming convention to prevent collisions between different modules.

Naming Conventions

Module Class

Every module that is injected into a page receives a CSS class that is derived from the package and module name.

company_product_module

In addition, a CSS class derived from just the package name is also added to the module.

company_product

company is substituted by the company name of the package owner. product is substituted by the product name (of the package). module is substituted by the module name (without trailing "Module").

For example the Text module is implemented by the YetaWF Text package, so its CSS class would be "YetaWF_Text_Text", where YetaWF_Text is the company/product name followed by an underscore and the module name "Text". In addition the CSS class "YetaWF_Text" is also added to the module.

Local Classes

CSS classes with the prefix "t_" are intended for use within modules/components only and indicate a CSS class local to a module or component. Only modules or components should use "t_" CSS classes.

<div>s and other tags within any module or component use CSS classes with the "t_" prefix. These CSS classes may collide with CSS classes elsewhere. Therefor a t_xxxx CSS class must always be specified with the module or component CSS class.

Component Classes

CSS classes with the prefix "yt_" are used by components (combined with their area name and component name). Skins and modules should never define a CSS class with a leading "yt_".

<div>s and other tags within any module or component use CSS classes with the "t_" prefix. These CSS classes may collide with CSS classes elsewhere. Therefor a t_xxxx CSS class must always be specified with the module or component CSS class.

Skin Classes

Skins may define their own classes as long as they don't collide with the naming conventions above. These CSS classes are considered global for the skin.

As only one skin can be active in a page, no conflicts are possible between different skins.
