What is sticky post ?
A sticky post means make any post remain at top of the page.
In wordpress blogging platform, you can do it on their dashboard. But in blogspot you can’t, because blogspot has no option like sticky post.
So we have to play with date.
Create a post that you want to make remain on the top, and publish it. Then immediately edit the post. Now while editing, you need not have to edit anything in the content zone, but you have to change the date of publishing – to any future date.
this date format : mm/dd/yr
