Hello,
As you can see the template of this blog has been given an overhaul. It was made possible because Blogger introduced a new feature a while ago. It is called 'template designer' and is accessible by going to Blogger Dashboard>Layout>Template Designer. It allows you to alter everything from the background colour of your blog to the colour links turn when the pointer hovers over them. Best of all you don't need any knowledge of HTML or CSS. It also comes with additional templates. However some of the older templates may not be compatible with the new template designer in which case you would have to switch templates. The template let me have gadgets along both sides. The right side is for third party and miscellaneous gadgets and the left side is for gadgets affiliated with this blog. The new template that I had to choose because of the problem I just highlighted allows me to insert more than one row of gadgets at the bottom of the page. I inserted two polls and a small note along with the Back to Top link that was there previously. Please do at least one of the polls.
The Blog Author :)
PS: None of your gadegets are deleted when you change your template.
