I was wanting to add a new gadget to one of my blogger blogs, so I opened up the Templates - Edit HTML window and started browsing the template file. While in there, in the body of the template - blow the css coding - I noted a string of text that reads: <div id='main-wrapper'> <b:section class='main' id='main' showaddelement='no'> I changed the showaddelement to yes, thus so: <div id='main-wrapper'> <b:section class='main' id='main' showaddelement='yes'> In doing so, I was able to add new gadgets to the main body of the page, where it appears on every page of the blog. You can view the final output here: http://byte-sized-marketing.blogspot.com/ I hope you find it as useful as I did.
I discovered this little trick when I was searching for a way to put adsense between the header and the body. It's a cool trick! You can use it anywhere there is an 'add element'. The place to use it for the adsense trick is in the header. That way, you can put a gadget between the header and body.
