Easy jQuery Affix,Scrollspy And Reading Progress Plugin - newsAffix

newsAffix is a simple-to-use jQuery affix / scrollspy / reading progress plugin used to generate a sticky header navigation & scroll progress indicator for your long web content.


  • Highlights the nav items when you you scroll past their content sections.
  • Displays a progress bar to indicate the reading progress of current content section.
  • Scrolls smoothly between content sections by clicking on the nav items.

How to use it:

1. Create content sections where you want to apply the newsAffix plugin.

<div id="targeted-wrapper" class="content">

  <section class="content__section">
    <h2 class="content__title js-na-header-start" data-na-header="1">Header title 1</h2>
    <p class="content__text">Section 1</p>

    <h3 class="content__subtitle">This is sub-title 1</h3>
    <p class="content__text">Sub Section 1</p>

  <section class="content__section">
    <h2 class="content__title" data-na-header="2">Header title 2</h2>
    <p class="content__text">Section 2</p>

    <h3 class="content__subtitle">This is sub-title 2</h3>
    <p class="content__text">Sub Section 2</p>

  <section class="content__section">
    <h2 class="content__title" data-na-header="3">Header title 3</h2>
    <p class="content__text">Section 3</p>

    <h3 class="content__subtitle">This is sub-title 3</h3>
    <p class="content__text">Sub Section 3</p>

  <section class="content__section">


2. Load jQuery library and the jQuery newsAffix plugin at the end of the document.

<script src="//code.jquery.com/jquery.min.js"></script>
<script src="js/jquery.newsAffix.js"></script>

3. Initialize the plugin with default options.
