Well I have most often seen bloggers removing the footbar of blog to hide the name of the templates. So i have found a way to know the name of template. Note it is not 100% effective but work in nearly all cases. e.g till now i have found no blog whoes template name i cannot Know.
1: SO first step is to open the blog's address. in this case I am doing it with myself.
2: Now Right click on the page and click view page source.
3: Now the source of the Blog will appear like this:
4: Now Scroll down to find the text like below:
NOW YOU CAN CLEARLY SEE THE TEXT WHICH TELLS THE NAME OF THE TEMPLATE , IT'S AUTHOR AND WEBSITE.
Hope you enjoyed!!!!
