Custom HTML template for images you insert in posts

How to Create Image Slider without Plugin (almost)

In this tutorial I am going to show you how you can easily create your own WordPress image sliders and carousels without overloading your website with tons of plugins.

A quick disclaimer though – if you’re using Gutenberg editor or Full Site Editing in WordPress, then probably a better idea would be to create a block for that purpose.

But in this tutorial we are going to use just custom fields (or options) and an external carousel JavaScript library.
