I have grid-focus running.

currently my posts looks like the following…

I would like to make it look like following

basically I would like to have the “Posted by Author” after the title
and then after the post content, I would like to have a straight line followed by the date and then the “number of comments”

can this be done?

is it possible?

Can I have some help please?
