Class Name Conventions

Infusion components use various conventions for defining CSS class names. These conventions prevent confusion, making it easier for developers and integrators to be clear on what's what when creating or using components.

CSS classnames

The template for CSS classnames (i.e. class names use for styling) take the form fl-[fluid:thing]-[fluid:role]-[fluid:state] with some guidelines:

  1. multiple words are in camelCase, so they might look like fl-[fluid:multiWordThing]-[fluid:multiWordRole]-[fluid:state]
  2. components are always the first "thing", so they would look like fl-[fluid:componentName]-[fluid:thing]-[fluid:role]-[fluid:state]

[fluid:thing] = required the concept the class name is referring to at the most general yet still meaningful level (eg. fl-tabs, fl-widget, fl-col, fl-container, etc)

[fluid:role] = optional the purpose or action of THING, which could be a more detailed version of THING (eg. fl-tabs-centered, fl-col-flex, fl-container-500, fl-widget-titleBar)

[fluid:state] = optional a modifier of the ROLE or THING, which is only temporary and dependant on other actions (eg. fl-button-left-disabled, fl-widget-content-draggable)

Some examples of these class names:

  • fl-col-flex: a flexible width column
  • fl-tabs-left: left-oriented tabs
  • fl-grid-caption: the caption of an image in a grid
  • fl-widget-titlebar: the titlebar of a widget

Infusion selectors

The template for Infusion selectors (i.e. classnames used for programmatic manipulation of the DOM) take the form


with the same guidelines as CSS selectors.

Some examples of component selectors:

  • flc-progress-label: the label for a progress bar (Progress component)
  • flc-reorderer-dropWarning: the drop warning used with the reorderer (Reorderer component)
  • flc-inlineEdit-textEditButton: the 'edit' button used with an inline edit (Inline Edit component
  • flc-pager-pageLink-skip: a page link that should be skipped (Pager component)

When combining class names for styling and class names for selectors, the convention is

<el class="flc-* fl-*">

so that the DOM selectors are before the CSS selectors.
