Is Visible Directive

The is visible directive is a small libary to help the user add or remove classes to an HTML-Element (div / a / img / etc. ), if the Element is in the viewport.

Floating animations can be managed in a good way via Html and Css without a single line of javascript code

How to Use

the latest version is build and pushed in the dist/index.js folder and can be included on any Webseite.

Code Example

<div data-add-class="fade-in" class="box invisible" data-class-offset="1">
  <div>
    The Box!
  </div>
</div>

The data-add-class will manage which class needed to be added when the Box is in the view port

With the attribute data-class-offset the use can manage the offset, while an offset of 1 is if the Box is totaly in the viewport and 0.1 means that the fade-in class will be added when 10% of the Box is in the viewport

<div data-remove-class="red" class="box red" data-class-offset="1">
  <div>
    The Box 3!
  </div>
</div>

The data-remove-class will manage which class needed to be removed when the Box is in the view port
