Nucleus .Net Core CMS: Web application framework and content management system for .Net Core

CSS Reference

Admin

Admin CSS classes in Resources/css/admin.css can be used by Settings views and Control Panel Extensions.

.nucleus-button-panel Class used to wrap buttons at the bottom of a form. Buttons are rendered side-by-side with a small gap between them and a small top and bottom margin.
.flex-fill Specifies that a control should fill the available width. Controls within a <SettingsControl> already fill the available width by default.
.nucleus-index-wrapper This class is intended to be used on a div which wraps a list of entries and an editor panel, which are rendered side-by-side.
.nucleus-index-items This class is intended to be used on a div which is a child of .nucleus-index-wrapper, and which wraps an ul element. It sets styles on the list and list items so that "items lists" are presented consistently.
.nucleus-editor-panel When applied to a div which wraps an editor, applies flex styles to the panel (div), and any child forms or fieldsets so that they fill the available space.
.nucleus-modal-caption When applied to a heading h1,h2,h3,h4,h5,h6 element, specifies the caption for your settings page. The content of the element is moved to the heading area of the dialog which contains your settings page.

Shared

CSS classes in Resources/css/shared.css are always available. CSS Classes which are used by Nucleus but are not intended for use by extensions are not included here.

.fs-small Render text at 0.9rem.
.fs-smaller Render text at 0.8rem.
.btn.btn-none Render a plain button control with no background, padding, border or margin.
.nucleus-material-icon Use the Google Material Icons font.
.ValidationError The ValidationError class is automatically applied when a controller action returns a BadRequest(ControllerContext.ModelState) response. It highlights controls with invalid content.
.modal-auto-size.modal-dialog When applied to a bootstrap modal (.modal-dialog), the .modal-auto-size class overrides Bootstrap's modal width constraints and renders a modal that uses 80% of available screen width. It also stretches content elements so that button rows are displayed consistently at the bottom of the dialog
.w-min-fit-content The w-min-fit-content class is intended for table cells. It applies width: 1px; white-space: nowrap; which causes the table cell to use the minimum width possible but still fit content without wrapping.
.progress .indeterminate When applied to a Bootstrap progress bar ().progress) the .indeterminate class renders the progress as an indeterminate progress bar, so you can use a progress indicator when you don't know how long the operation will take.
.nucleus-small-cell When applied to a table cell, renders the cell with width: 20px. Use this class for table cells which contain a single small button.
.ToggleSwitch Apply the .ToggleSwitch class to an input[type=range] control to automatically enable the ToggleSwitch plugin.

Forms

Forms CSS classes can be used by any part of Nucleus, including extensions, but Viewer views must include forms.css by adding a call to @Html.AddStyle("~/Resources/css/forms.css") as forms.css is only automatically included in admin pages.

.nucleus-flex-fields When applied to a <div> or another wrapper element, child elements are rendered in the same row (side-by-side).
.settings-control This class is used to style elements which are rendered by the <SettingsControl> tag helper. It applies styles to present input, select and other controls consistently.
.nucleus-form-tools Class used to wrap buttons in the body of a form. Buttons are rendered side-by-side with a small gap between them.
.nucleus-form-buttonrow Class used to wrap buttons at the bottom of a form. Buttons are rendered side-by-side with a small gap between them and a small top margin.
