Adding custom DIV on the presentation page, LF help

Hello, i’ve been customizing my website with this theme, and most of the stuff is done, at least on presentation page.

Now, i’d like to add a div and write some text inside to indicate that blog posts are below, but i have no idea where to put that part of the code, or better say in which file.

I would want it to look like this:

Link to image.

So basicaly, the orange/red part is blank atm, but i would like to put a div on that spot. I guess it will have to be notepad work.

Thanks for reading.

NVM, solved this one after bit of playing.

I just had to add <div>Stuff</div> on top of wp-content\themes\tempera\content\content-frontpage.php and that solved my thing.
