You'll need a post's ID is you want to display a Featured Post on the homepage using Jefferson.
Appearance > Customize > Homepage > Featured Post.
For me, the quickest and easiest way to find a post ID is done from the All Posts screen – found by logging into the WordPress dashboard and clicking Posts > All Posts.
From here, simply hover your mouse over the post you want to find the ID for. Now, take a look in the bottom left-hand corner of the screen.
See that pop-up box? That contains the post ID.
More specifically, the post ID is the number that comes after the “post=” and before the “&”.
See what I mean in the above screenshot? In this instance, my post ID is 668.
You can also find a post ID by clicking on the post you want, to open up the WordPress editor.
When done this way, the post ID is in the address bar. The URL shown will be exactly the same, and the post ID is again sandwiched between the “post=” and the “&”.
