# Material Design Lite
##Introduction
## Introduction
**Material Design Light (MDL)** is a library of components for web developers based on Google's **Material Design** philosophy: "A visual language for our users that synthesizes the classic principles of good design with the innovation and possibility of technology and science." Understanding the goals and principles of Material Design is critical to the proper use of the MDL components. If you have not yet read the [Material Design Introduction](http://www.google.com/design/spec/material-design/introduction.html), you should do so before attempting to use the components.
The MDL components are created with CSS, JavaScript, and HTML. You can use the components to construct web pages and web apps that are attractive, consistent, and functional. Pages developed with MDL will adhere to modern web design principles like browser portability, device independence, and graceful degradation.

To obtain the components, clone or download the [GitHub MDL repository](https://github.com/google/material-design-lite). Copy the entire package (the top-level folder and everything below it) to the project folder where you will write your HTML pages. This ensures that your project can access all of MDL's components and assets, and that you always have the original files for reference in case you break something. :-)

>**A note about HTML elements and MDL CSS classes**
>Material Design Lite uses CSS *independent classes*, which can apply to any HTML element, to construct components. For some components, you can use almost any element. For other components, some elements give better visual or behavioral performance than others. The examples in each component's README file use elements that perform well as that component. If you must use elements other than those shown in the examples, we encourage you to experiment to find the best combination of HTML elements and MDL CSS classes for your application.

The Material Design Lite (MDL) **badge** component is an onscreen notification element. A badge consists of a small circle, typically containing a number or other characters, that appears in proximity to another object. A badge can be both a notifier that there are additional items associated with an object and an indicator of how many items there are.
You can use a badge to unobtrusively draw the user's attention to items they might not otherwise notice, or to emphasize that items may need their attention. For example:

The Material Design Lite (MDL) **button** component is an enhanced version of the standard HTML `<button>` element. A button consists of text and/or an image that clearly communicates what action will occur when the user clicks or touches it. The MDL button component provides various types of buttons, and allows you to add both display and click effects.
Buttons are a ubiquitous feature of most user interfaces, regardless of a site's content or function. Their design and use is therefore an important factor in the overall user experience. See the button component's [Material Design specifications page](http://www.google.com/design/spec/components/buttons.html) for details.
The available button display types are *flat* (default), *raised*, *fab*, *mini-fab*, and *icon*; any of these types may be plain (light gray) or *colored*, and may be initially or programmatically *disabled*. The *fab*, *mini-fab*, and *icon* button types typically use a small image as their caption rather than text.

The Material Design Lite (MDL) **card** component is a user interface element representing a virtual piece of paper that contains related data &mdash; such as a photo, some text, and a link &mdash; that are all about a single subject.
Cards are a convenient means of coherently displaying related content that is composed of different types of objects. They are also well-suited for presenting similar objects whose size or supported actions can vary considerably, like photos with captions of variable length. Cards have a constant width and a variable height, depending on their content.
Cards are a fairly new feature in user interfaces, and allow users an access point to more complex and detailed information. Their design and use is an important factor in the overall user experience.

The Material Design Lite (MDL) **checkbox** component is an enhanced version of the standard HTML `<input type="checkbox">` element. A checkbox consists of a small square and, typically, text that clearly communicates a binary condition that will be set or unset when the user clicks or touches it. Checkboxes typically, but not necessarily, appear in groups, and can be selected and deselected individually. The MDL checkbox component allows you to add display and click effects.
Checkboxes are a common feature of most user interfaces, regardless of a site's content or function. Their design and use is therefore an important factor in the overall user experience. See the checkbox component's [Material Design specifications page](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-checkbox) for details.

The Material Design Lite (MDL) **data-table** component is an enhanced version of the standard HTML `<table>`. A data-table consists of rows and columns of well-formatted data, presented with appropriate user interaction capabilities.
Tables are a ubiquitous feature of most user interfaces, regardless of a site's content or function. Their design and use is therefore an important factor in the overall user experience. See the data-table component's [Material Design specifications page](http://www.google.com/design/spec/components/data-tables.html) for details.
The available row/column/cell types in a data-table are mostly self-formatting; that is, once the data-table is defined, the individual cells require very little specific attention. For example, the rows exhibit shading behavior on mouseover and selection, numeric values are automatically formatted by default, and the addition of a single class makes the table rows individually or collectively selectable. This makes the data-table component convenient and easy to code for the developer, as well as attractive and intuitive for the user.

The Material Design Lite (MDL) **footer** component is a comprehensive container intended to present a substantial amount of related content in a visually attractive and logically intuitive area. Although it is called "footer", it may be placed at any appropriate location on a device screen, either before or after other content.
An MDL footer component takes two basic forms: *mega-footer* and *mini-footer*. As the names imply, mega-footers contain more (and more complex) content than mini-footers. A mega-footer presents multiple sections of content separated by horizontal rules, while a mini-footer presents a single section of content. Both footer forms have their own internal structures, including required and optional elements, and typically include both informational and clickable content, such as links.
Footers, as represented by this component, are a fairly new feature in user interfaces, and allow users to view discrete blocks of content in a coherent and consistently organized way. Their design and use is an important factor in the overall user experience.

The Material Design Lite (MDL) **layout** component is a comprehensive approach to page layout that uses MDL development tenets, allows for efficient use of MDL components, and automatically adapts to different browsers, screen sizes, and devices.
Appropriate and accessible layout is a critical feature of all user interfaces, regardless of a site's content or function. Page design and presentation is therefore an important factor in the overall user experience. See the layout component's [Material Design specifications page](http://www.google.com/design/spec/layout/principles.html) for details.
Use of MDL layout principles simplifies the creation of scalable pages by providing reusable components and encourages consistency across environments by establishing recognizable visual elements, adhering to logical structural grids, and maintaining appropriate spacing across multiple platforms and screen sizes. MDL layout is extremely powerful and dynamic, allowing for great consistency in outward appearance and behavior while maintaining development flexibility and ease of use.

The Material Design Lite (MDL) **shadow** is not a component in the same sense as an MDL card, menu, or textbox; it is a visual effect that can be assigned to a user interface element. The effect simulates a three-dimensional positioning of the element, as though it is slightly raised above the surface it rests upon &mdash; a positive *z-axis* value, in user interface terms. The shadow starts at the edges of the element and gradually fades outward, providing a realistic 3-D effect.
Shadows are a convenient and intuitive means of distinguishing an element from its surroundings. A shadow can draw the user's eye to an object and emphasize the object's importance, uniqueness, or immediacy.
Shadows are a well-established feature in user interfaces, and provide users with a visual clue to an object's intended use or value. Their design and use is an important factor in the overall user experience.

## Introduction
The Material Design Lite (MDL) **spinner** component is an enhanced replacement for the classic "wait cursor" (which varies significantly among hardware and software versions) and indicates that there is an ongoing process, the results of which are not yet available. A spinner consists of an open circle that changes colors as it animates in a clockwise direction, and clearly communicates that a process has been started but not completed.
A spinner performs no action itself, either by its display nor when the user clicks or touches it, and does not indicate a process's specific progress or degree of completion. The MDL spinner component provides various types of spinners, and allows you to add display effects.
Spinners are a fairly new feature of most user interfaces, and provide users with a consistent visual cue about ongoing activity, regardless of hardware device, operating system, or browser environment. Their design and use is an important factor in the overall user experience.

## Introduction
The Material Design Lite (MDL) **switch** component is an enhanced version of the standard HTML `<input type="checkbox">` element. A switch consists of a short horizontal "track" with a prominent circular state indicator and, typically, text that clearly communicates a binary condition that will be set or unset when the user clicks or touches it. Like checkboxes, switches may appear individually or in groups, and can be selected and deselected individually. However, switches provide a more intuitive visual representation of their state: left/gray for *off*, right/colored for *on*. The MDL switch component allows you to add both display and click effects.
Switches, particularly as a replacement for certain checkboxes, can be a valuable feature in user interfaces, regardless of a site's content or function. Their design and use is therefore an important factor in the overall user experience. See the switch component's [Material Design specifications page](http://www.google.com/design/spec/components/selection-controls.html#selection-controls-switch) for details.
The enhanced switch component has a more vivid visual look than a standard checkbox, and may be initially or programmatically *disabled*.

## Introduction
The Material Design Lite (MDL) **tab** component is a user interface element that allows different content blocks to share the same screen space in a mutually exclusive manner. Tabs are always presented in sets of two or more, and they make it easy to explore and switch among different views or functional aspects of an app, or to browse categorized data sets individually. Tabs serve as "headings" for their respective content; the *active* tab &mdash; the one whose content is currently displayed &mdash; is always visually distinguished from the others so the user knows which heading the current content belongs to.
Tabs are an established but non-standardized feature in user interfaces, and allow users to view different, but often related, blocks of content (often called *panels*). Tabs save screen real estate and provide intuitive and logical access to data while reducing navigation and associated user confusion. Their design and use is an important factor in the overall user experience. See the tab component's [Material Design specifications page](http://www.google.com/design/spec/components/tabs.html) for details.

The Material Design Lite (MDL) **text field** component is an enhanced version of the standard HTML `<input type="text">` and `<input type="textarea">` elements.

The Material Design Lite (MDL) **tooltip** component is an enhanced version of the standard HTML tooltip as produced by the `title` attribute. A tooltip consists of text and/or an image that clearly communicates additional information about an element when the user hovers over or, in a touch-based UI, touches the element. The MDL tooltip component is pre-styled (colors, fonts, and other settings are contained in *material.min.css*) to provide a vivid, attractive visual element that displays related but typically non-essential content, e.g., a definition, clarification, or brief instruction.
Tooltips are a ubiquitous feature of most user interfaces, regardless of a site's content or function. Their design and use is an important factor in the overall user experience.

## Introduction
The Material Design Lite (MDL) **typography** component is a comprehensive approach to standardizing the use of typefaces in applications and page displays. MDL typography elements are intended to replace the myriad fonts used by developers (which vary significantly in appearance) and provide a robust, uniform library of text styles from which developers can choose.
The "Roboto" typeface is the standard for MDL display; it can easily be integrated into a web page using the CSS3 `@font-face` rule. However, Roboto is most simply accessed and included using a single standard HTML `<link>` element, which can be obtained at [this Google fonts page](http://www.google.com/fonts#UsePlace:use/Collection:Roboto).
Because of the many possible variations in font display characteristics in HTML and CSS, MDL typography aims to provide simple and intuitive styles that use the Roboto font and produce visually attractive and internally consistent text results. See the typography component's [Material Design specifications page](http://www.google.com/design/spec/style/typography.html) for details.
##Basic use
