Of course, you’re not just restricted to the ready-made themes Weebly offers you – you can use the Code Editor in Weebly to create something of your own! The easiest way is to start with an existing theme and change it as you need. Simply open up the theme, and then click Edit HTML/CSS at the bottom of the Theme Page. You can either edit HTML, CSS, and JSON files directly in the editor, or export them to an external editor and re-import your new theme once you’re finished.
