Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

+ add another resource

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

    <summary>Notes on using Switches</summary>
    <p>
      A situation one should try to avoid is having "switches" that run full width of a browser's viewport. As rarely is the label of a switch alone an effective means to determine the current state of the control.  
    </p>
    <p>
      When they label and UI of the control are positioned on opposite ends of the viewport, people who may be using software to magnify portions of their screen at a time are likely not going to see the label and the state in the same magnified window.
    </p>
    <p>
      Keeping the label and the switch UI closer together will help ensure that the state and label will be easier to visually associate with each other. It also increases the likelihood that they may both be visible in a magnified portion of hte screen.
  </p>
    <hr>
    <p>
      While these elements are visually represented as switch controls, they're semantically conveyed as checkboxes.  Use caution when representing an element as one type of control to some people, but announcing it as a different control to others.
    </p>
    <hr>
    <p>
      Note that the example 2a and b "switches" will not render exactly as intended with IE11, or in earlier versions of Firefox (pre 60).

Checkbox inputs posing as "switches".

Ideally if needs to redesign a checkbox to look like a switch, then the control would also announce itself and act like a swtich to assistive technologies, such as screen readers.
