Part 8: sidebar.php
This is also a very simple file. Here is the file: sidebar.txt.
It’s actually really simple, the same as php includes. You have the div for sidebar which is part of your container and after that you have the content of your sidebar. You customize it as you want. And then you close the sidebar div and that’s it.
The sidebar.php file will be linked to the rest of your theme in footer.php
