Hi just did my first project can you please tell what to do better

why can i not copy and paste it has now all disappeared?

It looks like you tried to copy your code into the FCC template without forking the pen. For the projects , you need to have a codepen account (which is free) and then fork the template.

Here are some directions on how to do that.

An alternative method, would also be to still create your own account but instead of forking the pen you could just use the FCC CDN link within the script tag like this.

<script src="https://cdn.freecodecamp.org/testable-projects-fcc/v1/bundle.js"></script>

You can find this link on the instructions page for the project.

Hope this helps.
