So, Drupal is like a big toy box full of all kinds of toys for building websites! It has all the pieces you need to build a really great website, like blocks, modules, and themes.
Blocks are like building blocks that you can use to build different parts of your website. For example, you might use a block to make a menu or to add an image to your website.
Modules are kind of like add-ons for your toy box. They give you new tools and toys to play with! They help you do things like add a contact form to your website or add a shopping cart for people to buy things from your site.
Themes are like costumes for your website. They help you change the way your website looks, so it can be more fun and exciting! You can choose from lots of different themes, like superhero themes or princess themes.
The coolest thing about Drupal is that you don't have to be a grown-up to use it! Kids just like you can use Drupal to build really cool websites. Plus, it's free to use, so it won't cost you any money to build your own website!
