Signatures are very smart way to show your trade mark or logo, you may simply write your name or add logo of your business.
Edit your signature by any image editor and make a jpg file
<div class='post-footer-line post-footer-line-1'>
if not found then try to find it:
<p class='post-footer-line post-footer-line-1'>
or this one
a) if only one person is writting as an author thenadd this below:
write your signature URL up there
b) if more then one are authors then
If you have more number of authors, you can repeat the blocks accordingly(here i have mentioned 2 blocks[blue and brown] one for each of the two authors).Codes should be edited with the author names and the signature image urls.
5.Save your template and you should see the signature in action 🙂
