- ## Introduction
- 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.
- ## Basic use
- To use any MDL component, you must include the minified CSS and JavaScript files using standard relative-path references in the `<head>` section of the page, as described in the MDL Introduction.
- ### To include an MDL **mega-footer** component:
- 1a. Code a `<footer>` element. Inside the footer, include one `<div>` element for each content section, typically three: *top*, *middle*, and *bottom*.
- ```html
- <footer>
- <div>
- ...
- </div>
- <div>
- ...
- </div>
- <div>
- ...
- </div>
- </footer>
- ```
- 1b. Add the appropriate MDL classes to the footer and divs using the `class` attribute.
- ```html
- <footer class="mdl-mega-footer">
- <div class="mdl-mega-footer__top-section">
- ...
- </div>
- <div class="mdl-mega-footer__middle-section">
- ...
- </div>
- <div class="mdl-mega-footer__bottom-section">
- ...
- </div>
- </footer>
- ```
- 2a. Inside the top section div, code two sibling "inner" divs for the *left* and *right* content sections.
- ```html
- <footer class="mdl-mega-footer">
- <div class="mdl-mega-footer__top-section">
- <div>
- ...
- </div>
- <div>
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__middle-section">
- ...
- </div>
- <div class="mdl-mega-footer__bottom-section">
- ...
- </div>
- </footer>
- ```
- 2b. Add the appropriate MDL classes to the two "inner" left and right divs using the `class` attribute.
- ```html
- <footer class="mdl-mega-footer">
- <div class="mdl-mega-footer__top-section">
- <div class="mdl-mega-footer__left-section">
- ...
- </div>
- <div class="mdl-mega-footer__right-section">
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__middle-section">
- ...
- </div>
- <div class="mdl-mega-footer__bottom-section">
- ...
- </div>
- </footer>
- ```
- 3a. Inside the middle section div, code one or more sibling "inner" divs for the *drop-down* content sections. That is, for two drop-down sections, you would code two divs.
- ```html
- <footer class="mdl-mega-footer">
- <div class="mdl-mega-footer__top-section">
- <div class="mdl-mega-footer__left-section">
- ...
- </div>
- <div class="mdl-mega-footer__right-section">
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__middle-section">
- <div>
- ...
- </div>
- <div>
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__bottom-section">
- ...
- </div>
- </footer>
- ```
- 3b. Add the appropriate MDL classes to the two "inner" drop-down divs using the `class` attribute.
- ```html
- <footer class="mdl-mega-footer">
- <div class="mdl-mega-footer__top-section">
- <div class="mdl-mega-footer__left-section">
- ...
- </div>
- <div class="mdl-mega-footer__right-section">
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__middle-section">
- <div class="mdl-mega-footer__drop-down-section">
- ...
- </div>
- <div class="mdl-mega-footer__drop-down-section">
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__bottom-section">
- ...
- </div>
- </footer>
- ```
- 4a. Inside the bottom section div, code an "inner" div for the section heading and a sibling unordered list for the bottom section links.
- ```html
- <footer class="mdl-mega-footer">
- <div class="mdl-mega-footer__top-section">
- <div class="mdl-mega-footer__left-section">
- ...
- </div>
- <div class="mdl-mega-footer__right-section">
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__middle-section">
- <div class="mdl-mega-footer__drop-down-section">
- ...
- </div>
- <div class="mdl-mega-footer__drop-down-section">
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__bottom-section">
- <div>
- ...
- </div>
- <ul>
- ...
- </ul>
- </div>
- </footer>
- ```
- 4b. Add the appropriate MDL classes to the "inner" div heading and list using the `class` attribute.
- ```html
- <footer class="mdl-mega-footer">
- <div class="mdl-mega-footer__top-section">
- <div class="mdl-mega-footer__left-section">
- ...
- </div>
- <div class="mdl-mega-footer__right-section">
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__middle-section">
- <div class="mdl-mega-footer__drop-down-section">
- ...
- </div>
- <div class="mdl-mega-footer__drop-down-section">
- ...
- </div>
- </div>
- <div class="mdl-mega-footer__bottom-section">
- <div class="mdl-logo">
- </div>
- <ul class="mdl-mega-footer__link-list">
- ...
- </ul>
- </div>
- </footer>
- ```
- 5. Add content to the top (left and right), middle (drop-downs), and bottom (text and links) sections of the footer; include any appropriate MDL classes using the `class` attribute.
- ```html
- <footer class="mdl-mega-footer">
- <div class="mdl-mega-footer__top-section">
