Everything I am going to show here could have been done by creating my own template but as I wanted to ensure that it would be future proof I have done it with CSS, a tiny bit of javascript, and existing Cassiopeia template options.
Over the last few weeks I have been rebuilding a joomla website that was built with a pagebuilder using just core Joomla and the core Cassiopeia template. This wasn't for a client, it was just as an exercise to satisfy my own belief that you don't need a pagebuilder.
Why are you using a so-called page builder when Joomla has everything you probably need right in the box? Don't know what I am talking about - well it's a fairly hidden feature of the TinyMCE editor called Content Templates.
