I have a blogger blog and beside the sidebar, I inserted a html gadget for adsense codes. And because the ads automatically appear on the left sidebar, I inserted the to create space and move it further close to the middle. I used to work fine but lately I notice that the ads will appear at the left area even though there's  . I'm using firefox for viewing or is there something wrong with the way the codes are inserted?
Take a look with firebug, chances are theres a style putting the javascript in a specific location - and you should be using a div with a style to move the gadget over too. Much better than a space.
Since its Javascript, the $nbsp; should work. But if your CSS is conflicting with allocated space, it will be ignored and pushed around. In general, using the spaces is best avoided. CSS can move things around much more effectively.
Sorry, I really appreciate your reply. But I don't really get what you mean. Can you please help to rephrase the sentence? I'm a noob in this Any particular html code to use??
