The source code is a kind of instruction that tells your browser how your website should be displayed and what content it has.
The homepage builder allows you to create a homepage within minutes and with a few mouse clicks. What you insert and see in your page editor is transformed by us into instructions for your internet browser.
If you want to take a look at the source code, visit your website and press the key combination Ctrl+U.
At first glance, you will see a lot of characters and letters next to the content you have written, which can be a bit confusing at first. However, without all these instructions, your web page would not look the way it does now.
These "confusing characters" are also called "HTML tags" in technical language. They are supplemented by javascripts and CSS instructions.
