How to Add the Announcement Widget or Scrolling Headline Widget to Blogger Blogs

   Today, I will like to produce another tutorial for Bloggers out there on How to add an announcement widget to your blogger blog; this announcement widget can be used for several purposes ranging from making an announcement on your blog, putting up a blog update notice, showing links to your featured posts etc.
 
   The Widget has scrolling headlines which start scrolling immediately your blog loads and
it stops scrolling the moment you point your mouse on the links in the widget so that you can easily read the headlines.You can see the widget and how it works here…

Wow!!! I like this Widget, How will I add it to my Blog?
1. Login to
Blogger > click on Layout.
2. And then click on Add a Gadget (wherever you want the widget to be) then scroll down and click on HTML/JavaScript Widget.
3. Now a new empty box opens, Paste the following codes into the box -

<style type="text/css">
/*Example CSS for the two demo scrollers*/
#pscroller2{
background:url(http://4.bp.blogspot.com/-7ZFQXCvcnjQ/TlfjPMxiBJI/AAAAAAAAEzM/jrV-qvI_xqM/s400/updates1.gif) no-repeat top left;
width: 450px;

4. You can make the following changes to make the widget match your blog perfectly –
  • To change the Loudspeaker image, replace http://4.bp.blogspot.com/-7ZFQXCvcnjQ/TlfjPMxiBJI/AAAAAAAAEzM/jrV-qvI_xqM/s400/updates1.gif with your preferred image’s URL.
  • If you want to increase or decrease the scroller width size, then adjust this 450px.
  • Replace StevenBergy.Com.Ng with anything you wish to write as the announcement or blog update.
  • Replace www.stevenbergy.com.ng with the announcement link or URL. On clicking this link, the visitors will be taken to the announcement page. But if you don't want to link your announcement to any URL then simply delete www.stevenbergy.com.ng next to each StevenBergy.Com.Ng that you don't wish to add a link to.
  • To change the speed at which the announcement changes, adjust 500 and note that the more you increase this value the slower the links will scroll and vice versa.
   5. After adjusting and customizing this widget to suit your taste, click on Save and now you are good to go!!! You will now see the beautiful widget scrolling and changing headlines on your blog.
