<header class="bar bar-nav">
  <a class="icon icon-left-nav pull-left" href="#"></a>
  <h1 class="title">Page Title</h1>
</header>
  1. Implementing a toggle switch:
<div class="toggle">
  <div class="toggle-handle"></div>
</div>
  1. Adding a segmented control:
<div class="segmented-control">
  <a class="control-item active" href="#item1">
    Item 1
  </a>
  <a class="control-item" href="#item2">
    Item 2
  </a>

Competitor Comparisons

Materialize, a CSS Framework based on Material Design

Pros of Materialize

  • More comprehensive and feature-rich framework with a wider range of UI components
  • Active development and community support, with regular updates and improvements
  • Better documentation and examples, making it easier for developers to implement

Cons of Materialize

  • Larger file size, which may impact page load times for smaller projects
  • Steeper learning curve due to more complex structure and customization options
  • May require more effort to override default styles for highly customized designs

Code Comparison

Materialize:

<div class="row">
  <div class="col s12 m6">
    <div class="card blue-grey darken-1">
      <div class="card-content white-text">
        <span class="card-title">Card Title</span>
        <p>Card content</p>
      </div>
    </div>
  </div>
</div>

Ratchet:

<div class="card">
  <ul class="table-view">
    <li class="table-view-cell">
      <a class="push-right" href="#">
        Card content
      </a>
    </li>
  </ul>
</div>

Both frameworks offer mobile-first responsive design, but Materialize provides a more modern and visually appealing set of components out of the box. Ratchet, while lighter and focused on mobile interfaces, has not been actively maintained in recent years, which may limit its compatibility with newer web technologies.

The most advanced responsive front-end framework in the world. Quickly create prototypes and production code for sites that work on any kind of device.

Pros of Foundation

  • More comprehensive framework with a wider range of UI components and features
  • Better documentation and community support
  • Regularly updated with new features and improvements

Cons of Foundation

  • Steeper learning curve due to its extensive feature set
  • Larger file size, which may impact page load times
  • More complex customization process

Code Comparison

Ratchet (HTML):

<header class="bar bar-nav">
  <h1 class="title">Title</h1>
</header>

Foundation (HTML):

<div class="top-bar">
  <div class="top-bar-left">
    <ul class="menu">
      <li class="menu-text">Title</li>
    </ul>
  </div>
</div>

Both frameworks provide ways to create navigation bars, but Foundation offers more flexibility and customization options. Ratchet's syntax is simpler, while Foundation's approach allows for more complex layouts and responsive designs.

Foundation generally requires more markup and CSS classes to achieve similar results, which can lead to more verbose code. However, this additional complexity often translates to greater control over the final output and better responsiveness across different screen sizes.

A lightweight and modular front-end framework for developing fast and powerful web interfaces

Pros of UIkit

  • More comprehensive framework with a wider range of UI components
  • Active development and regular updates
  • Extensive documentation and community support

Cons of UIkit

  • Larger file size and potentially heavier load on the browser
  • Steeper learning curve due to more complex structure
  • May require more customization to achieve a unique design

Code Comparison

Ratchet (HTML):

<header class="bar bar-nav">
  <h1 class="title">Title</h1>
</header>
<nav class="bar bar-tab">
  <a class="tab-item active" href="#">
    <span class="icon icon-home"></span>
    <span class="tab-label">Home</span>
  </a>
</nav>

UIkit (HTML):

<nav class="uk-navbar-container" uk-navbar>
  <div class="uk-navbar-left">
    <ul class="uk-navbar-nav">
      <li class="uk-active"><a href="#">Home</a></li>
    </ul>
  </div>
</nav>

UIkit offers a more modern and flexible approach to building UI components, with a larger variety of options and customization possibilities. However, this comes at the cost of increased complexity and file size. Ratchet, while simpler and more lightweight, is primarily focused on mobile interfaces and has a more limited set of components. The choice between the two depends on the specific project requirements, target devices, and desired level of customization.

Semantic is a UI component framework based around useful principles from natural language.

Pros of Semantic-UI

  • More comprehensive UI framework with a wider range of components and themes
  • Better documentation and community support
  • Modular architecture allowing for easy customization and extension

Cons of Semantic-UI

  • Larger file size and potentially slower load times
  • Steeper learning curve due to its extensive features
  • Less focused on mobile-first design compared to Ratchet

Code Comparison

Semantic-UI button example:

<button class="ui button">
  Follow
</button>

Ratchet button example:

<a class="btn">
  Follow
</a>

Both frameworks offer simple ways to create UI elements, but Semantic-UI provides more customization options out of the box. Semantic-UI uses class-based styling, while Ratchet relies on predefined classes for basic elements.

Semantic-UI is a more feature-rich framework suitable for larger projects with diverse UI needs, while Ratchet is lightweight and focused on mobile web apps. The choice between them depends on project requirements, target devices, and development preferences.

Modern CSS framework based on Flexbox

Pros of Bulma

  • More active development and maintenance
  • Larger community and ecosystem
  • Responsive design out of the box

Cons of Bulma

  • Larger file size
  • Steeper learning curve for beginners
  • Less focused on mobile-first design

Code Comparison

Bulma:

.button {
  background-color: #00d1b2;
  border-color: transparent;
  color: #fff;
}

Ratchet:

.btn {
  background-color: #428bca;
  border: 1px solid #357ebd;
  color: #fff;
}

Both frameworks provide pre-styled button classes, but Bulma uses more modern CSS properties and a flatter design approach. Ratchet's syntax is closer to Bootstrap, which may be more familiar to some developers.

Bulma offers a more comprehensive set of components and utilities, making it suitable for a wider range of projects. However, this comes at the cost of a larger file size and potentially more complex class structures.

Ratchet, being specifically designed for mobile prototyping, has a smaller footprint and simpler class names. This makes it easier to get started with, especially for mobile-focused projects. However, its limited scope and lack of recent updates may be a drawback for more complex or modern web applications.

Troubleshooting

A small list of "gotchas" is provided below for designers and developers starting to work with Ratchet.

  • Ratchet is designed to respond to touch events from a mobile device. In order to use mouse click events (for desktop browsing and testing), you have a few options:
    • Enable touch event emulation in Chrome (found in the overrides tab in the web inspector preferences)
    • Use a JavaScript library like fingerblast.js to emulate touch events (ideally only loaded from desktop devices)
  • Script tags containing JavaScript will not be executed on pages that are loaded with push.js. If you would like to attach event handlers to elements on other pages, document-level event delegation is a common solution.
  • Ratchet uses XHR requests to fetch additional pages inside the application. Due to security concerns, modern browsers prevent XHR requests when opening files locally (aka using the file:// protocol); consequently, Ratchet does not work when opened directly as a file.
    • A common solution to this is to simply serve the files from a local server. One convenient way to achieve this is to run python -m SimpleHTTPServer <port> to serve up the files in the current directory to http://localhost:<port>

Versioning

For transparency into our release cycle and in striving to maintain backward compatibility, Ratchet is maintained under the Semantic Versioning guidelines. Sometimes we screw up, but we'll adhere to these rules whenever possible.

Releases will be numbered with the following format:

<major>.<minor>.<patch>

And constructed with the following guidelines:

  • Breaking backward compatibility bumps the major while resetting minor and patch
  • New additions without breaking backward compatibility bumps the minor while resetting the patch
  • Bug fixes and misc changes bumps only the patch
