To Always Show Mobile Nav
For any design that requires the mobile icon to be showing at all times (even desktop, like this one is doing), please go to site-options > header > always show mobile nav. You just need to toggle this option to save writing code trying to fight the bundled stuff.
Clean Up
All the dummy data on this can be deleted in one go by going to FakerPress > Delete.
The dummy posts and images are helpful for quickly getting layouts done without worrying about assets.
Docs
There are docs being started for our setup that can be found here:
https://buildydocs.handmadeweb.com.au/
The docs will show you some of the hidden features here that you should look at before adding too much code, things might already be setup
Quick tips
Use template-parts for loops, look at the "content.php" one in there for the default postgrid. You can almost use the postgrid module for almost every custom loop by utilising template-parts.
Use PAGE ID's in URL fields (like buttons) rather than relative paths.
Read the "Module Styles" section of the docs.
