As blogging evolves, standard widgets often don’t meet the specific needs of modern bloggers. Custom widgets allow you to:

2. Adding a New Widget

To add a custom widget:

1. Click the “Add a Gadget” button in your desired layout position
2. Select “HTML/JavaScript” from the widget gallery

Setting Up Homepage Widget Sections

Here’s the code you’ll need to add a new widget section to your homepage:

<b:if cond='data:blog.pageType == "index"'>

    <b:widget id='CustomHTML1' type='HTML' title='Featured Content'>
      <!-- Your widget content goes here -->
    </b:widget>
  </b:section>

• FeaturedContent: Your section ID - choose something descriptive
• maxwidgets='3': Controls how many widgets you can add
• showaddelement='yes': Allows adding new widgets through the layout interface
• CustomHTML1: A unique identifier for your widget

Setting Up Post Page Widgets

For widgets that appear only on individual post pages:

<b:if cond='data:blog.pageType == "item" or (data:view.isLayoutMode)'>
  <b:section id='PostContent' class='widget-area' maxwidgets='3' showaddelement='yes'>
    <b:widget id='CustomHTML2' type='HTML' title='Post Widget'>
      <!-- Your widget content goes here -->
    </b:widget>
  </b:section>
</b:if>

Advanced Widget Customization

For more interactive widgets, you can incorporate JavaScript:

<div class="dynamic-content" id="dynamicWidget">
  <h3>Latest Updates</h3>
  <div id="content"></div>
  <script>
    const messages = [
      "Welcome to our blog!",
      "Check out our latest posts",
      "Don't forget to subscribe"
    ];
    let current = 0;
    
    function rotateContent() {
      document.getElementById('content').innerHTML = messages[current];
      current = (current + 1) % messages.length;
    }
    
    setInterval(rotateContent, 3000);
    rotateContent();
  </script>
</div>
