# Toolbars
The v-toolbar component is pivotal to any graphical user interface (GUI), as it generally is the primary source of site navigation. The toolbar component works great in conjunction with v-navigation-drawer and v-card.
# Usage
A toolbar is a flexible container that can be used in a number of ways. By default, the toolbar is 64px high on desktop and 56px high on mobile. There are a number of helper components available to use with the toolbar. The v-toolbar-title is used for displaying a title and v-toolbar-items allow v-btn to extend full height.
# API
# Caveats
When v-btns with the icon prop are used inside of v-toolbar and v-app-bar they will automatically have their size increased and negative margin applied to ensure proper spacing according to the Material Design Specification. If you choose to wrap your buttons in any container, such as a div, you will need to apply negative margin to that container in order to properly align them.
# Examples
# Props
# Background
Toolbars can display a background as opposed to a solid color using the src prop. This can be modified further by using the img slot and providing your own v-img component. Backgrounds can be faded using a v-app-bar
# Collapse
Toolbars can be collapsed to save screen space.
# Dense toolbars
Dense toolbars reduce their height to 48px. When using in conjunction with the prominent prop, will reduce height to 96px.
# Extended
Toolbars can be extended without using the extension slot.
# Extension height
The extension’s height can be customized.
# Floating with search
A floating toolbar is turned into an inline element that only takes up as much space as needed. This is particularly useful when placing toolbars over content.
# Light and Dark
Toolbars come in 2 variants, light and dark. Light toolbars have dark tinted buttons and dark text whereas dark toolbars have white tinted buttons and white text.
# Prominent toolbars
Prominent toolbars increase the v-toolbar's height to 128px and positions the v-toolbar-title towards the bottom of the container. This is expanded upon in v-app with the ability to shrink a prominent toolbar to a dense or short one.
# Misc
# Contextual action bar
It is possible to update the appearance of a toolbar in response to changes in app state. In this example, the color and content of the toolbar changes in response to user selections in the v-select.
# Flexible and card toolbar
In this example we offset our card onto the extended content area of a toolbar using the extended prop.
# Variations
A v-toolbar has multiple variations that can be applied with themes and helper classes. These range from light and dark themes, colored and transparent.
